In this paper the single curvature suspended roofs with transverse rib is discussed. It is composed of flexible cables and stiffening components. The transverse rib-stiffening components can be space trusses or space girders. Here the space trusses are taken as transverse rib. The cable is discretized into space linear cable element and it is assumed that the cable can transmit tension only. The nonlinear finite element equations are deduced. The trusses are discretized into space bar elements. In the part of dynamic analysis, the undamped forced vibration of structure under seismic loading is considered. And the influence of variation of structural designing parameters for the structure is discussed, from which some helpful conclusions are given.
