RISCyclic Testing of Two-Story Steel BRBFs for Evaluating Performance of Moderately Ductile Built-Up Box Columns under Varying Axial Load
Publisher: American Society of Civil Engineers
Abstract: A built-up box column is commonly used for the seismic resistance in buckling-restrained braced frames (BRBFs) in Asia. This research aimed to study the lateral cyclic performance of different compact built-up box columns ...
Effects of Continuity Plate and Transverse Reinforcement on Cyclic Behavior of SRC Moment Connections
Publisher: American Society of Civil Engineers
Abstract: Two exterior moment connections with a steel-encased reinforced concrete (SRC) column and a steel beam were tested to evaluate the cyclic performance. Continuity plates were eliminated in the first specimen, and about 60% ...
Development of a Compression-Only Self-Centering Brace with Buckling-Restrained Bars for Energy Dissipation
Publisher: American Society of Civil Engineers
Abstract: A steel brace is effective to retrofit old reinforcement concrete (RC) buildings by increasing the horizontal load capacity of structures. However, concrete cracks that easily occur in the surrounding RC members under ...
Effects of Section Compactness and SCWB Condition on Moment Redistribution and Plastic Hinging in SMF Built-Up Box Columns
Publisher: ASCE
Abstract: Steel special moment frames (SMFs) with built-up box columns and I-shaped beams commonly are used for seismic design, especially in Asian countries. Modern seismic design codes assume that plastic hinging will occur near ...
