Since the mid-1990s, a type of steel column that commonly features slender cross-sectional elements has become more prevalent in buildings along the West Coast

Projects and Programs

Seismic Performance of Steel Buildings in the Central and Eastern United States

Completed

Objective - This project will assess the seismic performance of structural steel SFRSs in buildings located in regions of moderate seismicity in the CEUS. The design of these building systems is commonly governed by wind demands. Two synergetic activities will be undertaken in this project: (1)

Advancing the Seismic Implementation of High Strength Reinforcement Bars in Reinforced Concrete Structural Wall Systems

Completed

Objective - To conduct a series of tests on wall and coupling beam components reinforced with Grade 60 A706 reinforcement and high-strength Grade 100 reinforcement. Cyclic tests will be conducted on isolated walls and on coupling beams. Individual walls are often joined together by coupling beams

Energy-based collapse assessment of framed structures for performance-based seismic engineering

Completed

Objective - The objective of this project is to develop a framework for evaluating structural performance and collapse due to seismic excitations based on an energy approach. The structural response obtained from nonlinear dynamic analysis is evaluated based on the amount of energy stored in the

Validation of ASCE 41 Procedures in PBSE

Completed

Objective - The objective of this study is to advance first-generation performance-based seismic engineering (PBSE) methods by assessing the performance of a set of code-compliant buildings using ASCE/SEI 41 methodologies. This study focuses on steel buckling-restrained braced frames (BRBFs) and
