For new large space plate-wall structure, the out-of-plane problems of shearwall caused by vertical loads cannot be ignored. The out-of-plane stiffness can be increased by introducing Hollow-shearwall. However, currently rare attention has been focused upon research on the out-of-plane problems of hollow-shearwall. Based on the theory of elastic thin plate，the hollow-shearwall is regarded as an orthotropic plate in this paper. According to the actual situation of the loading on the shearwall, it is the first time that the analytic solution of the hollow-shearwall with different boundary constraints under the combined action of the end moment and vertical pressure has been derived in this paper. The numerical results by the program developed with Mathematical based on the analytic solution are compared with those obtained with ANSYS and it shows that this method is correct and reliable. Under various operating conditions, it is easy to apply this program for the out-of-plane force analysis, which can provide reference for the further research on the out-of-plane capacity and a reliable basis for engineering design.
