| Abstract: | In order to study the in-plane deformation behavior of a new energy-saving wall,namely the foam-in-place cavity wall,13 patches of cavity walls and 1 patch of solid wall were built and tested.The dynamic hysteretic loop curves,the backbone curves and time history curves of displacement were obtained considering the variation of heights,ductility,energy dissipation and stiffness degradation.The effects of axial compression ratio,shape and layout of ties,and insulation layer thickness on structural seismic be... |
