RISComparative Seismic Response Evaluation of Steel Multistory and Multitiered Ordinary Concentrically Braced Frames
Publisher: ASCE
Abstract: Concentrically braced frames (CBFs) are widely used to resist lateral loads in buildings because they are relatively simple and economical to design and construct. In tall, single-story construction, it is often practical ...
Seismic Collapse Performance of Multitiered Ordinary Concentrically Braced Frames
Publisher: American Society of Civil Engineers
Abstract: In tall, single-story buildings with steel concentrically braced frame (CBF) lateral force resisting systems, it is more efficient to replace a single brace or pair of braces between the base and the story (roof) level ...
Seismic Response of Single-Degree-of-Freedom Systems Representing Low-Ductility Steel Concentrically Braced Frames with Reserve Capacity
Publisher: American Society of Civil Engineers
Abstract: Steel concentrically braced frames (CBFs) are used widely as a seismic lateral force–resisting system. Although modern CBFs designed for high seismic regions have considerable ductility, CBFs in moderate seismic regions ...
Strength and Ductility of HPS-100W I-Girders in Negative Flexure
Publisher: American Society of Civil Engineers
Abstract: In current AASHTO LRFD bridge design specifications, the nominal flexural strength of I-girders made from steel with a yield stress >345 MPa (>50 ksi) is limited to the yield moment rather than the plastic moment and ...
Seismic Design and Analysis of Steel Plate Shear Walls with Coupling
Publisher: American Society of Civil Engineers
Abstract: Special steel plate shear walls (SPSWs) are an economical seismic lateral force resisting system used throughout North America and Japan. Architectural constraints often encourage the designer to place a pair of planar ...
Innovations in Steel Design: Research Needs for Global Sustainability

Strong-Axis Stability of Wide Flange Steel Columns in the Presence of Weak-Axis Flexure
Publisher: American Society of Civil Engineers
Abstract: Column stability during seismic events is a critical consideration for all steel-framed structures, but is of particular importance for a unique class of steel frames called multitiered braced frames (MT-BFs). A MT-BF is ...
Large-Scale Cyclic Testing of Steel-Plate Shear Walls with Coupling
Publisher: American Society of Civil Engineers
Abstract: The steel-plate shear wall with coupling (SPSW-WC) system is a natural extension of the conventional steel-plate shear wall (SPSW) seismic force–resisting system. The SPSW-WC configuration is created by linking a pair of ...
Cyclic Flexural Testing of Concentrically Braced Frame Beam-Column Connections
Publisher: American Society of Civil Engineers
Abstract: This research investigates the cyclic flexural behavior and performance of concentrically braced frame beam-column connections in the context of evaluating the reserve lateral load-resisting capacity in concentrically ...
Field Behavior of Integral Abutment Bridges under Thermal Loading
Publisher: ASCE
Abstract: Integral abutment bridges (IABs) have become popular with departments of transportation throughout the United States due to their lower maintenance and construction costs and longer service life. Nevertheless, IAB design ...
