A STUDY OF POSSIBILITY OF PIN JOINED RC STRUCTURE WITH SHEAR DEVICES WHICH SHARE ALMOST WHOLE HORIZONTAL FORCE

摘要

A multi-story structural system composed of pin-jointed RC frame and passive response control devices is proposed in this paper. Story collapse caused by bending failure of continuous columns is serious problem in this structure. The purpose of this study is to clarify the conditions of the structural elements required to avoid story collapse. Dynamic response analyses are performed, and optimum strength distribution is found by trial-and-error method that determines strength distribution so that each story drift is as much as the others when earthquake motion is inputted to series-connected devices. And it is confirmed that optimum strength distribution is effective in avoiding story collapse.
