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...

This paper suggested a new connection protocol, adding cover-plate between shear links and column, which was used to enhance moment and shear carrying capacity of beam, relax the restriction and assure the sufficiency development of plastic deformation of the link, and dissipate more earthquake energy. Considering the scale ratio of 1:3, the experimental data was achieved by a specimen under cy...

This paper reviews selected recent innovations that expand the range of applicability of a number of new and emerging structural steel systems that can provide effective seismic performance. Focus is on recent developments on: (a) Steel Plate Shear Walls having light gauge infill plates; (b) Perforated Steel Plate Shear Walls; (c) Buckling Restrained Braced frames designed to meet Structural Fu...

Previous studies have underlined the importance of establishing a database high-fidelity benchmark experimental test results under random loading histories such as earthquake excitations for both existing structural systems well newly proposed ones. Such are useful understanding limitations previously developed numerical models, proposing new models more recently systems, better assessing ultra...

Seismic codes were developed to reduce the structural vulnerability and risk associated with earthquakes in earthquake-prone regions of world. The effectiveness code preventing damage is dependent on performance level defined construction technology employed. seismic fragility curves for two recent versions Iran are determined by using hybrid method. probability levels visualized these curves. ...
