摘　　要：为研究不同索结构形式拉索索力识别测试方法,满足不同类型空间结构模型试验的需要,开发了一种建筑空间结构通用模型试验平台,该模型试验平台包含主体结构及其增强装置和平台位移监测系统,主体结构采用正放四角锥螺栓球网架结构,增强装置为双向布置预应力拉索。利用有限元软件midas Gen对各类结构进行了模拟计算分析,该模型试验平台变形在合理范围内,应力分布较均匀,整体稳定性良好。In order to research the identification and testing methods of cable force in different cable structures and meet the test needs of different spatial structures models,a test platform for general model of building spatial structures is developed,including the main structure with normally placed quadrangular pyramid bolts grids,reinforcement devices of bidirectional prestressed cables and displaced monitoring system for platforms.Simulations and analysis on various structures are made with the help of the finite element software midas Gen,displaying the reasonable-level deformation of the model test platform,relatively well-proportioned stress distribution as well as satisfactory overall stability.
