Shear Resistance Mechanisms of High-Panelized Sheet Walls With Burring Holes

Abstract

High-panelized shear walls are employed in flat-buildings in seismically active regions. The walls that receive in-plane shear force allow shear stress to concentrate in intervals between the burring holes. Experiments and analyses showed that the values of shear stiffness without bending effects of 3.53~4.53-m-height walls were almost same and gradually decreasing according to the deformation increasing. The values of ultimate strength of the walls were also almost same, using cross-rails which were installed at equal pitches. Design values were estimated by the tension fields between the holes. The formulas of the allowable and ultimate strength were developed using the mechanisms.
