As　one　of　new　types　of　structural　systems,　the　cast-in-place　reinforced　concrete　grid　shear　wall　systems　have　functions　of　formwork,　strength　and　heat　preservation　at　the　same　time.　The　grid　shear　walls　consist　of　horizontal　members　and　vertical　members.　This　system　is　suitable　for　residential　buildings　in　seismic　and　non-seismic　areas　and　sustainable　development　of　construction　industry　in　China.　Four　reinforced　concrete　grid　walls　with　aspect　ratio　of　about　2　were　tested　under　the　combined　action　of　constant　axial　and　cyclic　lateral　loads,　Among　them　one　specimen　had　rectangular　cross　section,　one　had　T-shaped　cross　section,　and　the　other　two　walls　were　built　with　L-shaped　cross　sections.　This　research　was　conducted　to　assess　the　seismic　behavior　of　the　grid　shear　walls,　such　as　failure　mode,　hysteretic　characteristics,　deformation　capacity　and　bearing　capacityThe　test　results　indicated　that　all　the　specimens　failed　in　an　approximately　similar　way,　the　hysteretic　loops　of　the　lateral　load-displacement　were　asymmetric　and　pinch,　Drift　ratio　at　substantial　loss　of　lateral　load　capacity　was　2.8%　for　grid　structural　walls　with　flange　and　2%　for　rectangular　specimen.　The　deformation　capacity　was　the　largest　for　the　case　with　the　flange　in　compression,　while　deformation　capacity　was　the　smallest　for　the　exterior　vertical　member　in　compression.　©　International　Conference　on　Advances　in　Experimental　Structural　Engineering.　All　rights　reserved.
