EFFECTS OF LOADING METHODS ON RESTORING FORCE CHARACTERISTICS OF SHEAR WALLS IN TIMBER-FRAME-CONSTRUCTION AND THEIR MODELING METHODS : Study on restoring force characteristics of shear walls in timber-frame-construction for wind performance Part 1

Abstract

In this paper, two kinds of statically cyclic loading experiments are carried out in order to obtain the restoring force characteristics of timber framed shear walls for evaluation of wind resistance performance. The cyclic loading programs are made in consideration of features of wind forces. One of loading programs is carried out under displace control state and the other is carried out under load control state. The restoring force characteristics obtained from those experiments are modeled for response analyses. Although the basic idea of modeling is based on the combination of a normal bilinear model and a slip model, the reduction of stiffness and energy absorption ability, or shift of displacement are also taken into consideration.
