Prefabricated beam–column connections are the most vulnerable components of prefabricated buildings during earthquake events. The seismic performance connection is functional as critical component plays a key role in structural safety. This study aimed to develop novel hybrid concrete (HPC) connection, combining with wet and dry techniques, enhance frames. A quasi-static experimental investigat...

Abstract: Reduced Beam Section (RBS) and Drilled Beam Section (DBS) are seismic moment resistant frame connections, introduced after 1994 Northridge earthquake. RBS connection has been tested under cyclic loading and showed acceptable performance. In this paper, seismic behavior of Drilled Beam Section (DBS) connection is studied numerically using finite element method. A drilled beam section ...

To avoid the damage of connection due to overstrength beam strength, and alternation strength hierarchy in structural system, a novel precast concrete beam-to-column is proposed herein. In connection, replaceable energy-dissipation connector (REDC) was placed at bottom hidden corbel. addition, narrow vertical slot adjacent corbel reduce overstrength. First, features mechanical mechanism were di...

moment-resisting frames have extensive usage in earthquake-prone areas and high ability in energy dissipation.after the earthquake in northridge 1994,kobe 1995 fixed connections of steel structures have shown poor performance and generally they were caught brittle fracture of beam flange weld to the column.in order to remedy to avoid similar situations in future earthquakes,researchers introduc...

In this study, the behavior characteristics of I beam-to-concrete filled tube (CFT) column connection is studied through experiment and finite element models under the monotonic loading. To validate the finite element modeling, at first, an experimental model is made and experimented. After validation of the finite element modeling, different models were created in the software. The studied par...

Geometry of eccentrically braced frames (EBFs) in some cases causes the connection of link beam to the column. The details of such conditions should be studied carefully due to the full plastic rotation in the link beam. In this research, the behavior of link-to-column connection is modeled and the failure modes are considered. Based on the previous researches shear link can exhibit better beha...
