RISCyclic Quasi-Static Testing of Hollow Structural Section Beam Members
Publisher: American Society of Civil Engineers
Abstract: The efficient compression, torsion, and bending behavior of hollow structural sections (HSS) combined with their high strength-to-weight ratio provide an opportunity to further their use in seismic applications and improve ...
Cyclic Testing of Welded HSS-to-HSS Moment Connections for Seismic Applications
Publisher: American Society of Civil Engineers
Abstract: Hollow structural sections (HSS) are currently underutilized in seismic moment frame systems as possible alternatives to typical wide-flange members. To explore the potential use of HSS moment connections in seismic moment ...
Experimental Investigation of Foam-Filled CHS Braces under Cyclic Loading
Publisher: ASCE
Abstract: The performance of seismic braced frames can become compromised due to premature local buckling–induced fracture of the hollow structural section (HSS) steel braces. A strategy to delay the fracture of the braces is to ...
Influence of Seismic Design Evolution on the Seismic Collapse Behavior and Losses of Prototype Steel Buildings with Moment-Resisting Frames
Publisher: ASCE
Abstract: Seismic design provisions for steel moment frame buildings have undergone substantial changes over the past half century. Despite the anticipated benefits of enforcing newer codes, it is not yet fully known how the evolution ...
Seismic Vibration Control Using Superelastic Shape Memory Alloys
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Superelastic NiTi shape memory alloy (SMA) wires and bars are studied to determine their damping and recentering capability for applications in the structural control of buildings subjected to ...
Seismic Assessment of Concentrically Braced Steel Frames with Shape Memory Alloy Braces
Publisher: American Society of Civil Engineers
Abstract: The use of special concentrically braced frames has increased since the 1994 Northridge and 1995 Hyogoken–Nanbu Earthquakes. However, past performance suggests limited ductility and energy dissipation in braced frame systems ...
Cyclic Properties of Superelastic Shape Memory Alloy Wires and Bars
Publisher: American Society of Civil Engineers
Abstract: This study evaluates the properties of superelastic Ni–Ti shape memory alloys under cyclic loading to assess their potential for applications in seismic resistant design and retrofit. Shape memory alloy wire and bars are ...
Dynamic Modeling of In-Event Interdependencies in Community Resilience
Publisher: ASCE
Abstract: A simulation-based model designed to conduct in-event simulation for the assessment and quantification of seismic resilience of communities is presented. The proposed simulation approach employs a dynamic analysis that ...
Modeling Interdependencies between the Building Portfolio, Transportation Network, and Healthcare System in Community Resilience
Publisher: ASCE
Abstract: A community resilience model that takes into account the mutual interdependencies between the building portfolio, transportation network, and healthcare system both during and after a seismic event is presented. The model ...
Integrating Household Decisions in Quantifying the Seismic Resilience of Communities Subjected to a Sequence of Earthquakes
Publisher: ASCE
Abstract: A distributed simulation model is presented that integrates post-earthquake household decisions into quantifying the seismic resilience of communities subjected to a sequence of earthquakes. A simple multi-attribute rating ...
