THE OUTLINE AND THE POSSIBILITY OF THE SYSTEM AND THE EXAMINATION OF THE LOAD CONTROL JOINTS : The Studies on Exchangeable Earthquake Resisting Walls with The Load Control Joints Made of Precast Reinforced Concrete Part 1

Abstract

In order to secure the multistoried steel structures against earthquakes, the structural engineer have often used steel braces embedded in reinforced pre-cast concrete walls for the earthquake resisting element. We have devised the precast earthquake resisting walls for the object of the mid to high rise steel framed structures those had been made of the precast reinforced concrete, and fastened to the steel girders by high tension bolts through the load control joints at the head of the walls, not so as to produce the hindrance such as cracks. In this report, the authors have described the outline and the possibility of these system and the examination results of some load control joints.
