Abstract: PCa concrete curtain wall panels are attached to the structural frames by the jointing methods that enable the walls to rock or to sway, so as to be able to follow the horizontal displacement of the frames without sharing shear force. But, it was discovered from the results of the damage investigation caused by the Hanshin-Awaji earthquake, 1995 in Japan that some cracks occurred around the anchor bolts in concrete curtain walls.
The anchor bolts receive not only tensile force caused by negative wind pressure, but also shear force shared by the dead weight and seismic inertia force. While they are apt to be located near the corner of the thin walls, that is, the end distances or edge distances are short because of design details.
In this paper, the authors present the results of the experiments on the tensile and the shear strength of the anchor bolts with several kinds of anchor bolts shapes, that were embedded at short end distances or short edge distances in the full size walls. And propose the estimating method of the strength of these anchor bolts, then introduce the cautions and the measures on the occasion of the installing fasteners.
