Abstract:Holes for placing pipelines are usually opened on the building. In order to study impacts of the hole position on the seismic performance of short pier shear wall, six short-pier shear wall finite element models with the same opening hole sizes and different opening positions are built. The influences of the hole positions on seismic performances of hysteretic behavior, bearing capacity, ductility, energy dissipation of short pier shear wall are investigated under low cycle repeated loading, and through changing opening position under different axial compression ratio, the impacts of hole position on the seismic performance of short pier shear wall are discussed. The calculated results show that different opening positions affect the bearing capacity and the seismic performance of short pier shear wall remarkably. Under the same axial compression ratio, the nearer the hole opening position to the wall bottom, the greater the impact on the structure performance will be. And the axial compression ratio is higher , the influence will be more obvious.
