連層耐震壁付鉄筋コンクリート架構の履歴性状に及ぼす基礎浮上りの影響(その2)

Abstract

High rise building structures with shear walls are, recently, constructed for apartmenthouses and it is important to make clear anti-seismic safety of such buildings subjected tosevere earthquakes. In our former paper 1), up-lifting effects of the foundation of a shear wallwere examined statically and dynamically by using 1/20 scale test frame of reinforced con-crete structures. Two types of model structures similar to the former paper are added in thispaper: one is rigidly fixed to the base floor and the other is freely supported with a horizon-tal constraint. Test results as well as the results of former test are compared with the resultsof earthquake response analysis obtained by considering the restoring force characteristics ofthe reinforced concrete members.
