摘要
江苏省科学历史文化中心工程预应力吊拉多层外挑结构施工中,利用大型通用有限元软件ANSYS建立该结构及优化的关键节点有限元模型。在此基础上,采用合理的施工流程、张拉时机、测控方法、张拉控制应力、预应力损失和理论伸长值,为施工提供依据,社会经济效益良好。
In construction of prestress suspension muhilayer cantilever structure ol science, History anu Culture Center in Jiangsu Province, general-purpose finite element software ANSYS is adopted to establish the structure and optimized key node finite round model. On this basis, appropriate methods are adopted to deter- mine values of construction flow, stretching opportunity, control method, stretching control stress, prestress loss and theoretical expansion, so as to provide basis for construction. In this way, favorable socioeconomic perfor- mance has been achieved.
