THE ENVIRONMENTAL CRISIS AND THE SAFEGUARDING OF THE POPULATION'S HEALTH HAS LED TO RESEARCH INTO DIFFERENT WAYS OF MITIGATING HARMFUL GASES. AMONG THE EMISSIONS THAT THE WOOD INDUSTRY HAS SOUGHT TO REDUCE ARE THOSE OF FORMALDEHYDE, WHICH IS WHY NEW GREEN ADHESIVE METHODS FOR WOOD PANELS HAVE BEEN INVESTIGATED IN RECENT YEARS. IN THIS RESEARCH, PARTICLEBOARD WITH TWO BIO-BASED WOOD ADHESIVE (PB-BBWA) FORMULATIONS. THE FIRST PB-BBWA FORMULATION, BASED ON PROTEINS OBTAINED FROM COMPOUNDS FROM THE ALCOHOLIC BEVERAGE INDUSTRY, AND THE SECOND PB-BBWA FORMULATION, BASED ON PROTEINS FROM A MIXTURE OF COMPOUNDS FROM THE ALCOHOLIC BEVERAGE AND FOOD INDUSTRIES, WERE MANUFACTURED AND TESTED TO EVALUATE THE PHYSICAL?MECHANICAL, THERMAL AND FORMALDEHYDE EMISSION PROPERTIES OF UNTREATED AND UV-TREATED FORMULATIONS AT A LABORATORY SCALE. THE RESULTS OF THE PHYSICAL PROPERTIES OBTAINED IN THE PB-BBWA WERE SIMILAR OR EVEN BETTER THAN THOSE OF THE CONTROL PB. ADDITIONALLY, PB-BBWAS IMPROVE ON THE CONTROL PB SAMPLE?S JANKA HARDNESS BY LEAST 28%, AND A DECREASE IN THERMAL CONDUCTIVITY IN THE EDGEWISE POSITION AND FORMALDEHYDE EMISSIONS BY 12% AND 88%, RESPECTIVELY, IN COMPARISON TO THE CONTROL PB. THE TESTS PERFORMED EVIDENCED THAT PB-BBWAS SHOWED COMPARABLE PERFORMANCE AGAINST THE CONTROL PB MADE WITH UREA-FORMALDEHYDE AND SATISFIED INTERNATIONAL STANDARD REQUIREMENTS.

THIS PAPER INVESTIGATES THE APPLICATION OF A PROBLEM-BASED LEARNING (PBL) TEACHING METHODOLOGY TO A COURSE ON ENGINEERING PROJECT SCHEDULING, WHICH INTRODUCES THE CRITICAL PATH METHOD (CPM). DURING THIS COURSE, STUDENTS SOLVED REAL-LIFE CIVIL ENGINEERING PROBLEMS USING PBL TO COMPARE PBL WITH TRADITIONAL PROBLEM-SOLVING METHODS. IN THE EXPERIMENTAL DESIGN, THE STUDENTS WERE RANDOMLY DIVIDED INTO TWO GROUPS. TRADITIONAL TEACHING SESSIONS WERE IMPARTED TO THE FIRST GROUP, WHICH WAS DESIGNATED AS THE CONTROL GROUP, WHEREAS THE CPM WAS TAUGHT TO THE SECOND GROUP VIA THE PBL TEACHING METHODOLOGY. AFTER THE CLASSROOM SESSIONS, AN EVALUATION TOOL WAS APPLIED: RESPONSES WERE ANALYZED USING WILCOXON AND FISHER STATISTICS, AND A SET OF OPEN-ENDED QUESTIONS WERE QUALITATIVELY ANALYZED VIA A PATTERN-MATCHING TECHNIQUE. THE RESULTS FOR THE GROUP THAT UTILIZED PBL WERE FAVORABLE; THIS FINDING DEMONSTRATED THE EFFICIENCY OF THIS TOOL FOR TEACHING CPM. IN ADDITION, THE RESULTS FOR THE STUDENTS THAT APPLIED PBL METHODOLOGY DEMONSTRATED A HIGH DEGREE OF ACCEPTANCE OF THE CPM METHODOLOGY, WHICH MOTIVATES ITS IMPLEMENTATION INTO TEACHING OTHER SUBJECTS RELATED TO PROJECT SCHEDULING IN CIVIL ENGINEERING.

THIS PAPER PRESENTS THE RESULTS OF A SIMULATION MODEL REGARDING THE PRODUCTIVITY AND SAFETY WORKING SPACE FOR CONSTRUCTION WORKERS THROUGH THE FLOORS OF A BUILDING USING SWARM INTELLIGENCE (SI), A FIELD OF ARTIFICIAL INTELLIGENCE (AI), AND SPECIFICALLY USING ARTIFICIAL BEE COLONY (ABC) OPTIMIZATION. AFTER DESIGNING THE ALGORITHM USED TO BUILD THE SIMULATION MODEL, THE SIMULATION WAS USED IN AN ACTUAL BUILDING PROJECT BY COMPARING THE TRAVEL TIMES OF WORKERS CONVENTIONALLY TRANSPORTING MATERIAL WITH ANOTHER GROUP WORKING ON ROUTES OPTIMIZED BY THE ALGORITHM. THUS, THE PROPOSED ALGORITHM PROVIDES ROUTES COMBINING SHORTER TRAVEL TIMES AND CORRECT DISTANCES BETWEEN WORKERS WHEN TRANSPORTING MATERIALS IN A CONSTRUCTION SITE, HANDLING THE INTERFERENCE BETWEEN CREWS. AFTER VALIDATING THE ALGORITHM ON-SITE, NO STATISTICALLY SIGNIFICANT DIFFERENCES WERE FOUND BETWEEN THE TRAVEL TIMES OF WORKERS AND THE TIMES DELIVERED BY THE ALGORITHM. ADDITIONALLY, THE TRAVEL TIMES USING THE ROUTES OBTAINED THROUGH THE ALGORITHM WERE SIGNIFICANTLY LOWER THAN THOSE MADE BY WORKERS WHO MOVED FREELY WITHOUT A PREDEFINED ROUTE. IN SUMMARY, THE ALGORITHM PROPOSED MAY HELP CONSTRUCTION PRACTITIONERS MAINTAIN SAFE MOVEMENTS THAT RESPOND TO HAZARD CONTEXTS IMPOSED BY ANY RESTRICTION THAT DEMANDS A SAFETY DISTANCE.

THIS ARTICLE STUDIES THE FORT LA PLANCHADA, LOCATED IN SOUTHERN CHILE. CONSIDERING THE NATURE OF THIS NATIONAL MONUMENT, THE STUDY FOCUSES ON THE ANALYSIS AND CHARACTERIZATION OF ITS CONSTRUCTION ASPECTS: DESIGN, GEOMETRY, MATERIALITY AND CONSTRUCTION TECHNIQUES; ASPECTS THAT ARE PART OF THE POLIORCETICS (OR MILITARY ART) PERSPECTIVE. FROM A METHODOLOGICAL POINT OF VIEW, USING TECHNICAL HISTORICAL RESOURCES, RECONSTRUCTION OF THE FORT UNDER STUDY CULMINATED THROUGH A COMPREHENSIVE LITERATURE REVIEW AND ASSOCIATED FIELDWORK. THE ART OF POLIORCETICS AND CONSTRUCTION TECHNIQUES, AS USED BY MAJOR WRITERS OF THE 17TH CENTURY ABOUT FORTIFICATIONS AND THEIR PRINCIPLES, WERE APPLIED TO THE ORIGINAL CONSTRUCTION OF THE FORT, CONSIDERING THE DIFFICULTIES AND SOLUTIONS OF ITS TIME. THE CHARACTERISTICS OF THE ORIGINAL FORT AND THE ANALYSIS OF SUCCESSIVE REPARATIONS REVEALED THE EXISTENCE OF THREE DIFFERENT DESIGNS THROUGHOUT ITS HISTORY.

THE CONSTRUCTION INDUSTRY IS EXPERIENCING CHANGES IN ITS PROCESSES AND WORK METHODS, AND THE ADVANCEMENT OF NEW TECHNOLOGIES IN RECENT DECADES HAS LED TO A NEW CONCEPT KNOWN AS CONSTRUCTION 4.0, COINED IN 2016 IN GERMANY. SINCE ITS DEFINITION IS STILL DIFFUSE, IT WAS DEEMED NECESSARY TO CONDUCT A REVIEW ON THE PUBLICATIONS IN THIS FIELD TO GRASP HOW THIS CONCEPT IS BEING UNDERSTOOD. FOR THAT PURPOSE, A BIBLIOMETRIC ANALYSIS WAS CONDUCTED AMONG 260 RESEARCH ARTICLES USING SEVEN KEYWORDS. THE RESULTS REVEAL THAT THE NUMBER OF PUBLICATIONS IS GROWING EXPONENTIALLY, WITH THE USA, THE UK, AND CHINA BEING LEADERS IN THIS FIELD; BESIDES, FOUR TECHNOLOGIES ARE ESSENTIAL TO UNDERSTAND CONSTRUCTION 4.0 AT PRESENT TIME: 3D PRINTING, BIG DATA, VIRTUAL REALITY, AND INTERNET OF THINGS. THE RESULTS OF THIS REVIEW SUGGEST THAT FURTHER REVIEWS SHOULD BE CONDUCTED EVERY 3 YEARS TO GRASP THE RAPID EVOLUTION OF CONSTRUCTION 4.0.

VIBRATIONS ON TIMBER FLOORS ARE AMONG THE MOST COMMON SERVICEABILITY PROBLEMS IN SOCIAL HOUSING PROJECTS. THE PRESENCE OF LOW DAMPING LEVELS ON THESE FLOORS COULD CAUSE EXCESSIVE VIBRATIONS IN A RANGE OF FREQUENCY AND AMPLITUDE THAT GENERATE DISCOMFORT IN USERS. THIS STUDY FOCUSES ON THE INFLUENCE OF THE DAMPING RATIO IN THE DYNAMIC SERVICEABILITY OF SOCIAL HOUSING TIMBER FLOORS DUE TO WALKING EXCITATIONS. MORE THAN 60 HUMAN-WALKING VIBRATION TESTS WERE CONDUCTED ON BOTH LABORATORY AND IN-SITU TIMBER FLOORS. THE FLOORS WERE INSTRUMENTED WITH ACCELEROMETERS, AND FUNDAMENTAL MODAL DAMPING RATIOS WERE ESTIMATED BY APPLYING ENHANCED FREQUENCY DECOMPOSITION DOMAIN (EFDD) AND SUBSPACE STOCHASTIC IDENTIFICATION (SSI) METHODS. THE VIBRATION DOSE VALUE (VDV) WAS USED TO ESTIMATE THE DYNAMIC SERVICEABILITY OF FLOORS. THE RESULTS INDICATED THAT TIMBER FLOORS HAD AN IMPULSIVE-TYPE VIBRATION RESPONSE, WITH FUNDAMENTAL DAMPING RATIOS BETWEEN 1.9% AND 14.8%, DEPENDING ON THEIR CONSTRUCTIVE CHARACTERISTICS. THE IN-SITU FLOORS HAD DAMPING RATIOS BETWEEN TWO TO THREE TIMES GREATER THAN THE LABORATORY FLOORS DUE TO THE PRESENCE OF NON-STRUCTURAL ELEMENTS. FINALLY, IT WAS POSSIBLE TO DEMONSTRATE THAT THE FLOORS WITH THE HIGHEST DAMPING RATIOS REACHED LOWER VIBRATION DOSE VALUES AND, THEREFORE, A BETTER DYNAMIC SERVICEABILITY PERFORMANCE.

THIS STUDY AIMED TO EVALUATE THE EFFECT OF WATER IMMERSION ON THE RELEASE OF GROWTH STRESSES IN 17-YEAR-OLD EUCALYPTUS NITENS LOGS. A TOTAL OF 18 OF 90 TREES EVALUATED IN THE FIELD WERE SELECTED. THE AVERAGE DIAMETER AT THE HEIGHT BREAST OF ALL THE TREES WAS 37 CM. THE FIRST SECTION OF THE TREE, FROM THE STUMP TO 2.44 M, WAS USED. THREE STRESS LEVELS (LOW, MEDIUM, AND HIGH) WERE ESTABLISHED. SIX LOGS WERE STUDIED FOR EACH LEVEL, WHICH WAS DIVIDED INTO TWO GROUPS: THREE FOR CONTROL AND THREE FOR WATER IMMERSION. PERIPHERAL LONGITUDINAL STRAINS ON STANDING TREES, FRESHLY FELLING, AND AFTER THE IMMERSION PROCESS WERE DETERMINED BY AN EXTENSOMETER. THE DEFLECTION OF THE SAWN TIMBER AND LOG-END SPLITTING BEFORE AND AFTER AIR-DRYING WERE EVALUATED. IN ADDITION, THE DISTRIBUTION OF GROWTH STRESSES WAS DETERMINED. THE RESULTS SHOWED THAT DEFLECTION, THE LOG-END SPLITTING INDEX, AND STRESS DISTRIBUTION WERE REDUCED IN THE THREE LEVELS. THE WATER IMMERSION METHOD ALLOWED A REDUCTION OF GROWTH STRESSES IN EUCALYPTUS NITENS LOGS.

UNREINFORCED MASONRY WALLS (URM) ARE STRUCTURAL ELEMENTS USUALLY OBSERVED IN HERITAGE BUILDINGS IN CHILE. THE ASSESSMENT OF THE ELASTIC PROPERTIES OF THIS KIND OF STRUCTURES IS GENERALLY A CHALLENGING TASK, BECAUSE OF ITS ORTHOTROPIC BEHAVIOUR AND THE DIFFICULTIES TO EXTRACT AND TO HANDLE IN SITU SAMPLES FOR DESTRUCTIVE EXPERIMENTAL TESTS. THE STUDY PRESENTED HERE AIMS TO ESTIMATE THE ELASTIC MECHANICAL PROPERTIES OF URM WALLS BY APPLYING VIBRATION BASED NON-DESTRUCTIVE TECHNIQUES. A REPRESENTATIVE SEGMENT OF URM WALL WAS BUILT IN THE LABORATORY AND SUBJECTED TO A SERIES MODAL TESTS USING LOW ENERGY IMPACTS AS EXCITATION SOURCE. MODAL PROPERTIES OF THE WALL WERE ESTIMATED THROUGH ENHANCED FREQUENCY DOMAIN DECOMPOSITION (EFDD) AND STOCHASTIC SUBSPACE IDENTIFICATION (SSI) METHODS. AN ORTHOTROPIC FINITE ELEMENT MODEL OF THE WALL WAS SUCCESSIVELY UPDATING THROUGH GLOBAL SENSITIVITY ANALYSIS TECHNIQUES UNTIL THE DIFFERENCES BETWEEN EXPERIMENTAL AND NUMERICALLY SIMULATED MODAL PROPERTIES WERE MINIMAL. THE RESULTS SUGGEST THAT THIS APPROACH CAN BE EXTENDED TO MORE COMPLICATED STRUCTURAL CONFIGURATIONS.

IN CHILE, THE CONSTRUCTION SYSTEM OF CROSS-LAMINATED TIMBER PANELS (CLT) IS EMERGING AS AN ALTERNATIVE TO ACHIEVE THE GOALS OF SUSTAINABLE CONSTRUCTION IN A COUNTRY WITH HIGH SEISMICITY. THE STIFFNESS OF THIS STRUCTURAL SYSTEM DEPENDS MAINLY ON ITS CONNECTIONS, WHICH GENERALLY CONSIST OF STEEL ELEMENTS OF SMALL THICKNESS THAT ARE NAILED OR SCREWED TO THE WOOD. WHEN SEISMIC MOVEMENTS OCCUR, THESE JOINTS LOSE STIFFNESS DUE TO THE DAMAGE CAUSED BY THE FLUENCE OF THE CONNECTORS AND CRUSHING IN THE WOOD. THESE DAMAGES ARE USUALLY HIDDEN BY THE FINISHING BOARDS OF WALLS AND SLABS, SO IT IS DIFFICULT TO INSPECT THEM AFTER A SEISMIC EVENT. THE OBJECTIVE OF THE PRESENT WORK IS TO ESTIMATE THE LOSS OF STIFFNESS OF CLT WALLS THROUGH NON-DESTRUCTIVE VIBRATION-BASED TESTS. TWO CLT WALLS OF TWO-STORY HEIGHT (SECTION H 2400MM X 4200MM X 1200MM) ARE CONSTRUCTED, WITH THEIR RESPECTIVE CONNECTORS, AND THEN SUBJECTED TO NON REVERSIBLE CYCLIC HORIZONTAL LOAD TESTS. THE WALLS ARE INSTRUMENTED WITH ACCELEROMETERS, AND MODAL IMPACT TESTS ARE APPLIED AFTER EACH HORIZONTAL LOAD CYCLE, OBTAINING THE VARIATION OF THEIR DYNAMIC PROPERTIES. THE EXPERIMENTAL RESULTS SHOW THAT WHEN THE GLOBAL TANGENT STIFFNESS OF THE WALL REACHES 28% OF THE ORIGINAL VALUE, THE FUNDAMENTAL PERIOD OF VIBRATION INCREASE BY 1.52 TIMES. IN THIS WAY, THE POTENTIAL OF THIS NON DESTRUCTIVE TECHNIQUE FOR SEISMIC INSPECTION AND REHABILITATION OF BUILDINGS WITH CLT PANELS IS OBSERVED.

WOOD IS A GREAT MATERIAL, IT HAS A DISADVANTAGE OF EARLY DETERIORATION DUE TO EXTERNAL AGENTS. FOR THIS REASON, IT IS INTERESTING TO CREATE A NEW WOODEN PRESERVATIVE. IT WAS STUDIED ONE BASED ON A NATURAL POLYMER (CHITOSAN) AND NANOPARTICLES (SI AND TI). TESTS WERE CARRIED OUT TO CHARACTERIZE PHYSICAL (DENSITY, MOISTURE CONTENT, SWELLING AND ABSORPTION) AND MECHANICAL PROPERTIES (FLEXION, COMPRESSION AND HARDNESS) OF WOOD SPECIMENS WITH AND WITHOUT IMPREGNATION, AND THEIR JOINTS WITH TWO TYPES OF SELF-DRILLING SCREWS. SIMPLE AND LATERAL EXTRACTION TEST WERE CARRIED OUT. IMPROVEMENTS IN HARDNESS AND PERPENDICULAR COMPRESSION ARE HIGHLIGHTED OBTAINED, RESULTS INDICATE A STIFFENING OF THE FIBERS. THIS TREATMENT ACHIEVES THE MATERIAL CROSS SECTION HARDENING, COATING IT WITH COMPONENTS THAT HELP TO DELAY THE IGNITION AND PROVIDE GREATER DURATION AGAINST EXTERNAL AGENTS. FROM THE EXTRACTION OF SCREWS, THE IMPREGNATED WOOD ALLOWED MORE RIGID UNIONS, WITH SMALLER DISPLACEMENTS IN COMPARISON TO THE WOOD WITHOUT TREATMENT.

CROSS-LAMINATED-TIMBER (CLT) STRUCTURES HAVE GAINED POPULARITY IN THE FIELD OF MEDIUM-RISE BUILDINGS DUE TO THE QUICK FABRICATION AND ASSEMBLY OF THE PANELS. HOWEVER, CONNECTIONS IN RADIATA PINE CLT SHEAR WALLS AND THE BEHAVIOR OF CLT STRUCTURES UNDER LATERAL LOADS IS STILL NOT WELL UNDERSTOOD. IN THIS CONTEXT, THIS PAPER STUDIES THE STRUCTURAL BEHAVIOR OF HOLD-DOWN CONNECTIONS ON RADIATA PINE CLT WALLS BY MEANS OF EXPERIMENTAL TESTS AND NUMERICAL SIMULATIONS UNDER STATIC AND DYNAMIC CONDITIONS. THE TEST RESPONSE OF CONNECTIONS WAS REPLICATED BY CALIBRATING TWO HYSTERETIC MODELS ON OPENSEES. THE MAIN RESULTS SHOWED THAT APPLIED MODELS CAN REPRODUCE THE HYSTERETIC BEHAVIOR OF HOLD-DOWN CONNECTIONS WITH HIGH PRECISION. IT WAS OBSERVED THAT HOLD-DOWN CONNECTIONS ON RADIATA PINE CLT WALLS REACHED A LOADING CAPACITY SIMILAR TO OTHER WOOD SPECIES, BUT THE STRENGTH AND STIFFNESS DEGRADATION WAS QUICKER, AND NO SIGNIFICANT DIFFERENCE WITH THE PARALLEL TO GRAIN CAPACITY OF ANGLE BRACKET CONNECTIONS WAS NOTICED. IN ADDITION, IT WAS FOUND THAT RADIATA PINE CLT WALLS CAN ACHIEVE SUITABLE CYCLIC LOADING PERFORMANCE WITH LOW DAMAGE LEVEL IN CONNECTIONS AND REACH HIGH LEVELS OF DISPLACEMENT DUCTILITY. FINALLY, THE IMPORTANCE OF FRICTION IN THE LOAD CAPACITY OF THE WALL WAS ALSO SHOWN.

THIS STUDY EXAMINES THE FLEXURAL PERFORMANCE OF SIX 9-M FULL-SCALE TWO-SPAN NAIL-LAMINATED TIMBER CONCRETE (NLTC) COMPOSITE SLABS. THE SLABS WERE MADE WITH LUMBER BEAMS EDGE-JOINED WITH DOUBLE NAILING, END-JOINED WITH BUTT JOINTS, AND THE REINFORCED CONCRETE TOPPING CONNECTED WITH A SET OF NOTCHES, INCLINED SCREWS, OR A COMBINATION OF BOTH. THE MULTI-SPAN CONFIGURATION OF SLABS REDUCES THEIR DEFLECTIONS SIMPLY AND EFFECTIVELY. FIVEPOINT MONOTONIC BENDING TESTS WERE CONSIDERED FOR ALL SLABS. BEFORE FULL-SCALE SLABS, COMPRESSIVE AND TENSILE PULLOUT TESTS OF TIMBER-CONCRETE COMPOSITE (TCC) SHEAR CONNECTIONS WERE PERFORMED, INCLUDING NOTCHES AND INCLINED SCREWS. TENSILE PULL-OUT TESTS OF SHEAR CONNECTIONS WERE ALSO INCLUDED TO EMULATE THE NEGATIVE BENDING MOMENTS THAT OCCUR IN THE MIDDLE OF THE SLABS. FAILURE MODES, LOAD-MID-SPAN DEFLECTION RELATION, BENDING STIFFNESS, AND TIMBER-CONCRETE SLIP WERE EVALUATED FOR ALL SLABS. A DETAILED 3D MICRO-FINITE ELEMENT (FE) MODEL OF THE SHEAR CONNECTIONS WAS BUILT IN ANSYS SOFTWARE, WHEREAS A MACRO-FE MODEL OF NLTC SLABS WAS MADE IN SAP2000, DEMONSTRATING A GOOD FIT FOR THE TIMBER-CONCRETE INTERACTION AND THE LOAD-CARRYING CAPACITY OF THE COMPOSITE SLAB AT THE SERVICEABILITY RANGE. MOREOVER, AN ANALYTICAL ELASTIC TCC BEAM WITH THE GIRHAMMAR METHOD WAS ASSESSED AND DEMONSTRATED AS MORE PRECISE THAN THE TRADITIONAL GAMMA-METHOD. FINALLY, AN ACCURATE PREDICTION OF THE NUMERICAL AND ANALYTICAL (GIRHAMMAR) MODELS FOR THE BENDING STIFFNESS AT SERVICE LOADS UP TO 30% OF CAPACITY IS OBSERVED, WITH ERRORS IN A RANGE OF 2-23% AND 9-74%, RESPECTIVELY.

SINCE THE LARGE SEISMIC DEMANDS IN CHILE, THERE IS A HIGH LEVEL OF UNCERTAINTY REGARDING THE SEISMIC SAFETY BEHAVIOR OF TIMBER STRUCTURES. BESIDES, IN THE LAST DECADE, THERE HAS BEEN A WORLDWIDE RISE IN THE CONSTRUCTION OF CROSS-LAMINATED TIMBER (CLT) BUILDINGS, EXPLAINED BY THE EASE OF INDUSTRIALIZATION OF CLT PANELS AND FOR BEING A SUSTAINABLE MATERIAL. HOWEVER, ITS MASSIFICATION IN HIGH EARTHQUAKE-PRONE ZONES IS STILL UNDER DEVELOPMENT. THIS RESEARCH ANALYZES THE SEISMIC FRAGILITY OF A 5-STORY CLT BUILDING. THE AIM OF THIS RESEARCH IS TO DETERMINE THE SEISMIC SAFETY LEVEL OF A CLT MIDRISE BUILDING DESIGNED BY CHILEAN FORCE-BASED CODE REGULATIONS BY MEANS OF STATIC NONLINEAR ANALYSIS AND INCREMENTAL DYNAMIC ANALYSIS. FOR IDA CURVES, A SET OF 540 NONLINEAR TIME-HISTORY ANALYSES WERE PERFORMED USING PARALLEL COMPUTING TOOLS. THE MAIN RESULTS SHOW THAT FOR THE COLLAPSE OF THE BUILDING TO OCCUR, LARGE PSEUDO-ACCELERATION VALUES NEED TO BE REACHED. BESIDES, THE COLLAPSE MARGIN RATIO (CMR) IS CALCULATED FOR THE TWO PRINCIPAL DIRECTIONS, ACHIEVING VALUES LARGER THAN 3 FOR 50% COLLAPSE PROBABILITY. THESE RESULTS SUGGEST A LARGE MARGIN OF SEISMIC SAFETY OF THE CLT BUILDING DESIGNED IN THIS RESEARCH.
