Abstract

The purpose of this research is to develop the seismic reinforcement for PEB structure system and evaluate the seismic performance of PEB frames under cyclic load. The final goal of this research is to propose PEB system as steel ordinary moment frame system. Finite element analysis is performed before the experiment to develop the seismic joint reinforcement details of PEB structure system, called PI joint(${\pi}$ joint). PI joint has two types of joint details. One is tapered plate on the inner flange of rafter and column connection and the other is C-plate on the panel zone combined with tapered plate type. In this paper, the cyclic loading test is performed with three 3/8 scaled down PEB sub-assemblage frame specimen. The seismic performance of the specimens is evaluated by energy dissipation capacity, strength and response modification factor(R factor). As a result, it could be figured out that PEB can be categorized as steel ordinary moment frame and PI joint can enhance the seismic capacity of PEB structure.
