偏压作用下混凝土夹芯墙板理论研究

摘要

混凝土夹芯承重墙板其应用对我国墙体改革有着重要的意义.目前,该墙板在轴心受压情况下的力学性能已得到充分研究.但是,对于偏压作用下其力学性能的研究很少,故采用大型通用有限元分析软件ANSYS,对偏压作用下混凝土央芯承重墙板的力学性能进行非线性分析,研究了其在竖向偏压荷载作用下的变形特性和受力性能,提出了在偏压作用下混凝土夹芯承重墙板承载力计算公式.%Concrete sandwich wall-panel is a new developed building material. Its application in our country has important meaning to our national panel reform. At present, the mechanical properties of the wall panels under axial compression have been adequately studied. However, for the eccentric compression, the mechanical properties of the wall-panels are rarely studied. In this paper, by using nonlinear finite element program ANSYS, the mechanical behavior of the sandwich load-bearing panels under eccentric compression is analyzed. The calculated results, such as the characters of the deformation and stress, are discussed in detail. The formula for calculating bearing capacity under eccentric compression is obtained.
