EXPERIMENT ON IN-PLANE BEHAVIOR OF ALC PANEL EXTERIOR WALL SUBJECTED TO INERTIAL FORCE

Abstract

Autoclaved lightweight concrete (ALC) panel exterior walls are widely used in Japan, because they are expected to have high deformation capacity. However, during an earthquake, not only the in-plane deformation but also the out-of-plane inertial force are likely to act on the exterior walls. In this paper, combined in-plane and out-of-plane loading tests were conducted on ALC panel exterior walls. It was found that the deflection due to the out-of-plane load resulted in the earlier bearing state when the wall deform in the in-plane direction and the damage to the ALC panel exterior wall depends on the mounting hardware.
