Seismic characteristics of a T-shape resistant system

A particular structural lateral resistant system called „T-shape resistant system? (TRS) is introduced. This new form of framing system is constructed through a deep I-shaped steel beam vertically placed in the middle of span, connected with two other deep I-shaped beams to the columns at each storey level. In this paper, the R factor components including ductility reduction factor and over strength factor are extracted from inelastic pushover analysis of TRS having different heights and configurations. Then, by developing a nonlinear finite element model of a simple TRS system, the other properties of this system, such as energy dissipation characteristics, are properly investigated.
