Verification of Real-Time Hybrid Simulation With Shake Table Tests for a Three Story Structure Equipped with MR Damper
0.0 out of 5 stars
29 Jul 2014 | Publications | Contributor(s): Ali Irmak Ozdagli, Wang Xi, Gaby Ou, Shirley Dyke, Jian Zhang, Bin Wu
In the last few decades, Real-time hybrid simulation (RTHS) has become a recognized testing methodology for evaluating performance of structural components under potentially catastrophic events...
IMPROVING STEEL PLATE SHEAR WALL CODE DESIGN METHODOLOGY
11 Apr 2014 | Publications | Contributor(s): James T Enright
Current code based design of steel plate shear wall (SPSW) systems does not take into account the lateral force resistance provided by the moment resisting frame which bounds the web-plate. The...
