College of Civil Engineering , Beijing University of Technology, Beijing 100022, China A numerical analysis method for elastic-plastic seismic response of concrete block masonry is presented based on open system for earthquake engineering simulation system. The method simulates concrete block masonry by using equivalent frame model with rigid offsets; the space beam-column elements are simulated by force based nonlinear beam-column elements.

More precisely, we use the spherical coordinates for independent variables in space, and so avoid the approximation of boundary conditions on the surface, which is required, if we use the Descartes coordinates. Next, we use the Descartes coordinates for the components of velocity, which simplifies the actual computation and numerical analysis essentially.

The article covers the full research on such aspects as mathematic description, numerical analysis method and their practical applications. The diphase heating surface is divided into a hot water section, a evaporation section and a micro overheat section , the problems of model switching are avoided successfully between subcritical and supercritical working condition in the model of The diphase heating surface, and the model can be used for between subcritical and supercritical working condition without causing the model stiff infinity prick up problem. The mathematical model and dynamic characteristic account is unified and predigested for the diphase heating surface of once—through boiler under subcritical and supercritical pressure, and propose that the working conditions at phase change point could be used as divide criterion between water region and steam region under supercritical pressure, the problems are solved successfully between water and steam phase change point under supercritical pressure.
