Although the form of the new structure is like space truss,the member behavior is entirely different from the truss member which mainly bearing axial force,the polyhedron space frame member is like the beam with rigid connection in.

Optimization of geometric constitution of new polyhedron spatial frames;

Study on basic cells of new polyhedron spatial frames;

Modeling methods for polyhedron space frame structures;

The mechanics calculation of parabolic space rigid frame is v ery complicated,without being dealt with in issued directories,documents and tex tbooks.

The authors introduce the format of the data file and programming technique of the rigid frames,including the main program and general program of space rigid frame and node detail drawing.

Three-dimensional stiffness equations of uniform cross section bar are used so that the monent distribution coefficients for space frame without linear joint displacements are obtained.

The central rotational circular altar of Zhonghua Century Altar is a special dynamic structure of full steel and closed space frame.

In the present paper the non-linear static and dynamic post-buckling analysis of spatial frames is conducted.

The stationary random responses of tow layer spatial frame subjected to spatially coherent excitations are investigated and the pseudo static, the dynamic, and the total response variations are calculated.
