摘　　要：通过对江西新余文化健身中心训练馆网架的设计,对两个不同曲率的旋转曲面网架是否搭接计算进行论证,经过详细的计算比选,确定两网架应搭接计算,以达到受力合理、位移协调、经济美观的目的,且连接形式采用空间杆件连接为宜。同时介绍多义线旋转曲面网架的建模过程。According to the design of the grid frame for the training hall of Jiangxi Xinyu Cultural Fitness Center, it is demonstrated that the connection of two grid frames with different curvature should be calculated, so as to reach the target of reasonable force, displacement compatibility, economy and beauty, moreover, the space chord connection should be used. In the meantime, it is also introduced the modebbuilding process of rotatory grid frame with poly-line curved surface.
