The R/C frame structures were modeled with bar system and the column was modeled with multi-springs. The concrete and steel bars in column were considered as springs in order to reflect the coupling influence between the axial force and the moment-rotation relationship, the hysteresis of springs is based on the material properties and the rotation of column section is followed the plane assumption. The moment-rotation of beam section was modeled with trilinear hysteresis model.

Slipper type universal coupling"s fork joint and palm end are the weak parts of the main transmission system. In this article, the two parts" intensity values are obtained through finite element analysis . After making three-dimensional computer simulation analysis by ANSYS, the results show that the middle arc of the fork joint in loaded side and the intersection of fork bore and the arc are the danger location, where the stress is largest and stress concentration is serious.

T . There are six dependent variables; the pressure p , density r , and temperature T (which is contained in the energy equation through the total energy Et ) and three components of the velocity vector ; the u component is in the x direction, the v component is in the y direction, and the w component is in the z direction, All of the dependent variables are functions of all four independent variables.
