摘要
提出了利用铰支座解决复杂受力预应力框架结构内力不明确、柱子普矩过大、预应力张拉对结构产生的次内力难以确定等问题的方法,并在光华长安大厦剧场二层看台的设计、施工中实现。
A method is presented in the paper to solve the problem of undifinite internal form under complex loads, large bending moment of column and undifinite secondary force during prestressing of prestressed concrete frame structure using sliding bearings.The method was applied in the design and construction of the plateform of Guanghua Changan Building.
