Model Tests and Numerical Tests of In-Plane Seismic Property of Foam-In-Place Cavity Wall
摘要
Abstract
In order to study on the in-plane seismic property of foam-in-place cavity wall,and seek the effective measures to improve deformation capacity and overall performance of the cavity wall,13 patches of cavity walls and 1 patch of solid wall are built,and the model tests and numerical tests of the in-plane seismic property of foam-in-place cavity wall are carried out.The comparison indicates that the failure patterns,carrying capacity,deformation ability and coordination deformation ability of the numerical tests of foam-in-place cavity wall are agree with the data of model tests,and the validity and accuracy of the model tests and numerical tests are both verified.The experimental research shows that reinforced concrete strip ears play an important role in guaranteeing out-planes stability of the external wall.When wall crack seriously,the ties can play an important role in supporting and drawing the wall and preventing wall collapse.The reinforced concrete strip ears and ties are the main construction measures to coordinate the internal and external wall work together.Moreover,deformation capacity the cavity wall is improved efficiently with constructional column.According to working interactively between the internal and external wall of foam-in-place cavity wall,beneficial effects of external wall of foam-in-place cavity wall should be considered when anti-seismic shear resistance capacity is calculated.The results of model tests and numerical tests show that foam-in-place cavity walls have high bearing capacity and good coordination deformation capacity.关键词
