    Abstract:

    It presented a kind of nets forms,whose top boom was replaced by concrete slab and the bottom chord bar was replaced by pre-stressed cables.Structure model was framed and the structure's static characteristics were analyzed with ANSYS finite element software.When model was found,the structure was dispersed with slab elements,beam elements,pole elements and cable elements.And these elements interconnected with nodes while framing structure model.The conclusion is that the node displacement reaches the largest value in the center of the structure.And the node position is farther away from the center,the less of the node displacements.Also some plate elements have tension and others have pressure,so as the belly bars.The tension and pressure elements' positions are alternative.When the structure is forced by pre-stress and external load,the cables have tension.
