PURPOSE: RGA 01-21 ORDINARY STRUCTURAL WALLS SUBJECTED TO WIND AND SEISMIC LOADING PROTOCOLS: THIS RESEARCH INVOLVED LARGE SCALE TESTING ON ORDINARY REINFORCED CONCRETE WALLS WITH C-SHARPED AND RECTANGULAR CROSS-SECTIONS TO DEVELOP PERFORMANCE-BASED WIND DESIGN RECOMMENDATIONS FOR ACE COMMITTEES 375 AND 318.

PURPOSE: RGA -5-22 PERFORMANCE BASED STRUCTURAL FIRE DESIGN FOR AUTHORITIES HAVING JURISDICTION OFFICIALS: THIS PROJECT WILL DEVELOP EDUCATIONAL TRAINING MATERIALS TO INTRODUCE AJH TO THE TOPIC OF PERFORMANCE-BASED STRUCTURAL FIE DESIGN PBSFD. THESE MATERIALS WILL ASSIST AHJ TO GAIN AN UNDERSTANDING OF THE GOALS OBJECTIVES FIRE SCENARIOS THERMAL AND STRUCTURAL ANALYSES FOR PBSFD. AFTER COMPLETING THE TRAINING AHJ WILL BE ABLE TO REVIEW PBSDF DESIGNS ALONG WITH THEIR ASSUMPTIONS LIMITATIONS CAN CAVEATS. THEY WILL BE ABLE TO EFFECTIVELY MANAGE RELATIONSHIPS BETWEEN THE ENGINEERING TEAM AND THE PEER REVIEW PANEL AND MAKE FINAL DECISIONS BASED ON BUILDINGS CODES FOR STEEL CONCRETE MASONRY AND WOOD STRUCTURES. THE EDUCATIONS MATERIALS WILL INCLUDE SLIDES RECORDED PRESENTATIONS GUIDELINE DOCUMENTS RECORDINGS OF LIVE WORKSHOPS SEMINARS AND DISCUSSIONS BY EXPERT PANELS IN THE FIELD OF STRUCTURAL FIRE ENGINEERING FIRE PROTECTION ENGINEERING AND PERFORMANCE-BASED DESIGN.

PURPOSE: A-101.3 THIS RESEARCH PROJECT LOOKS TO ADVANCE METHODS FOR THE EFFICIENT ESTIMATION OF THE RELIABILITY OF POST-ELASTIC HIGH-RISE WIND-EXCITED STRUCTURES WITHIN A PERFORMANCE-BASED DESIGN PBD FOR HIGH-RISE BUILDINGS. PROFESSOR SEYMOUR SPENCE IS THE PRINCIPAL INVESTIGATOR AND IS QUOTED AS FOLLOWS: CURRENT HIGH-RISE STRUCTURAL WIND DESIGN IS HAMPERED BY DIFFICULTIES IN EFFICIENTLY MODELING THE POST-ELASTIC NON-LINEAR STRUCTURAL BEHAVIOR OF THE SYSTEM THEREFORE LEADING TO CHALLENGES IN ESTIMATING THE RELIABILITY OF THESE SYSTEMS AGAINST SEVERE WINDSTORMS. THIS RESEARCH SEEKS TO DEFINE A NEW PARADIGM FOR SOLVING THIS PROBLEM THROUGH THE DEVELOPMENT OF PROBABILISTIC DYNAMIC SHAKEDOWN FRAMEWORKS FOR THE INELASTIC ANALYSIS OF WIND-EXCITED STRUCTURES. THESE METHODS HAVE THE POTENTIAL TO PROVIDE TOOLS THAT ENABLE THE RAPID EVALUATION AS COMPARED TO TIME-HISTORY INTEGRATION OF THE POST-ELASTIC RELIABILITY OF A WIDE CLASS OF HIGH-RISE STRUCTURES."

PURPOSE: RGA #04-23 STEEL MASS TIMBER HYBRID DIAPHRAGMS AND VIBRATION: AIMS TO INVESTIGATE THE DIAPHRAGM AND VIBRATION BEHAVIOR OF STEEL-CROSS LAMINATED TIMBER CLT FLOORS. THIS RESEARCH WILL CATALYZE INNOVATION WITHIN THE BUILDING CONSTRUCTION FIELD BY ENABLING EFFICIENT AND EFFECTIVE DESIGNS OF STEEL-CLT FLOORS. STEEL-CLT BUILDINGS ARE CURRENTLY BEING CONSTRUCTED THROUGHOUT THE US. HOWEVER THE EXISTING DESIGN GUIDES FOR DIAPHRAGM AND VIBRATION DESIGN HAVE NOT BEEN DEVELOPED THROUGH EXPERIMENTAL DATA. THEREFORE THE DESIGN OF STEEL-CLT BUILDINGS MAY BE OVERLY CONSERVATIVE.

PURPOSE: FOUNDATION MATS WITH HIGH STRENGTH STEEL REINFORCEMENT #01-19: THE RESEARCH AIMS TO 1 OBTAIN ADDITIONAL DATA FOR A DEEP MEMBER WITH HIGH-STRENGTH LONGITUDINAL REINFORCEMENT AND WITHOUT SHEAR REINFORCEMENT THEREBY PROVIDING ADDITIONAL DATA FOR VERY DEEP MEMBERS THAT CAN INFORM THE ACI 318 ONE-WAY SHEAR EQUATIONS FOR VERY DEEP MEMBERS WITH LOW FLEXURAL REINFORCEMENT RATIO. 2 OBTAIN DATA FOR A SOIL-SUPPORTED DEEP MEMBER TO ADDRESS THE QUESTION OF WHETHER THERE ARE FUNDAMENTAL DIFFERENCES BETWEEN THE BEHAVIOR OF SOIL-SUPPORTED DEEP BEAMS AND SIMPLY SUPPORTED DEEP BEAMS.
