EXPERIMENTAL STUDY ON STRUCTURAL PERFORMANCE OF RC DAMAGE-CONTROLLED FLAT WALLS

Abstract

This study focuses on the RC secondary flat walls used as exterior/partition walls in typical residential buildings in Japan and proposes a new rebar arrangement for the walls, which removes wall vertical rebar anchorage to reduce earthquake damage. A series of cyclic loading tests of four full-scale RC secondary flat wall specimens was performed with two experimental parameters: presence or absence of the wall vertical rebar anchorage and quantity of confining reinforcement in the wall ends. Consequently, the performance limits were improved by removing the wall vertical rebar anchorage and increasing the quantity of confining reinforcement in the wall ends.
