Seismic excitation can cause significant energy to be released within structures. By using special devices, this consumed and dissipated without deforming structural members significantly. Due this, damage is minimized, casualties are prevented during earthquakes, structures extended in their useful life. Over the past five decades, it has been widely acknowledged that steel yielding dampers am...

Title of Document: NUMERICAL STUDY OF SEISMIC BEHAVIOR OF HIGH STRENGTH STEEL REPLACEABLE SHEAR LINKS Huiling Hu Master of Science, 2015 Directed By: Yunfeng Zhang, Professor Department of Civil and Environmental Engineering Eccentrically Braced Frames (EBFs) have been widely used in seismic protection and remediation in the recent years. However, the seismic behavior of shear links made of hig...

Received: November 02, 2017 Revised: January 12, 2018 Accepted: January 17, 2018 Abstract: Introduction: Retrofit interventions are often performed by introducing in structures dissipative devices able to improve the global seismic response particularly in terms of energy dissipation capacity. In the case of Concentric Braced Steel Frames (CBF), these devices are generally introduced in the for...

experimental tests were performed to study the seismic behavior and performance ofmodified steel chevron braced frame systems, which incorporate a vertical slotted connection(vsc) detail between the top of the braces and the floor beam above. the vsc detail isintended to prevent vertical load transfer to the beam and limit brace forces to thecompressive resistance of the members. full-scale qua...

Abstract A computational study was conducted to examine the seismic performance of steel moment‐resisting frames (MRFs) provided with chevron concentric braces. Such systems are widely used for buildings in Japan. Nonlinear finite‐element‐method models were validated against data and observations from previously tested chevron‐braced MRF specimens. The conduct a parametric understand how cyclic...

To reduce carbon emissions, holistic approaches to design, plan, and build our environment are needed. Regarding multi-story residential buildings, it is well-known that (1) material choices construction typologies play a fundamental role in the reduction of footprint, (2) shifting from concrete timber will significantly (3) building designed be disassembled increase potential achieving zero-ca...
