Seismic Performance of Welded Exterior Beam-Column Joint without Stiffeners

Abstract

This paper presents a static cyclic loading test of beam-column joint specimens made with H-section columns and beams. The features of the structures are; 1) beams and columns are connected by fillet welds, 2) No stiffeners are provided in the panel zone. Specimens are provided 2.5mm (FW25), 5.0mm (typical length in old Japanese construction, named as FW50), and 7.5mm (FW75) of the leg length, respectively. In addition, FW75_CPL specimen is tested which has cover plate for making H-section square. Test results showed that higher seismic performance when leg length increased and cover plate existed.
