Experimental Study on Frame Behaviors of Connections with Eccentricity between Steel Beams and Concrete-filled Square Tubular Steel Column Reinforced with Through Diaphragm

Abstract

This paper presents an investigation of the experimental studies on structural behaviors of connections, especially through diaphragm connection and connection panel, with eccentricity between steel beam and concrete-filled square tubular steel column subjected to incremental cyclic reversal loading. Four subassemblage specimens were tested with experimental variables of eccentricity, thickness of tube and connection type. The estimation methods for the strengths of through diaphragm connection and connection panel are proposed.
