EXPERIMENTAL STUDY ON COMPARISON OF PLASTIC DEFORMATION CAPACITY OF STEEL BEAM-TO-COLUMN CONNECTIONS

-COMPARISON BETWEEN THROUGH DIAPHRAGM TYPE CONNECTION AND BOLTED CONNECTION TYPE CONNECTION-

Abstract

This paper discusses the effect of connection details on plastic deformation capacity of steel beam-to-column connections. The subjects are beam end connection with either through-diaphragms, exterior-diaphragms or knee brace dampers. It is clarified from the experimental results that connections with exterior-diaphragms and knee brace dampers have two or three times plastic deformation capacity of connections with through-diaphragms, whose capacity have been improved more by many researches than before the Kobe earthquake.
