摘　　要：为解决斜拉网架结构减震装置造价高,位置和数量难以确定的问题,提出了斜拉局部三层网架的结构形式,利用ANSYS分析了这种结构的动力特性,并和斜拉双层网架对比,结果表明这种结构形式的抗震性能明显提高。It is difficult to solve the numbers,place and higher-prices about reduce seismic device with cable-stayed spatial gird structure.Cable-stayed partial three-layer spatial gird structure was presented,it＇s characteristic of dynamics was analyzed by ANSYS,compared with cable-stayed double-layer spatial gird structure.The conclusion is that anti-seismic capability of new style structure is better than that of the old structures.
