摘要
介绍双向预应力张弦梁结构的施工过程。根据有限元分析软件MIDAS的施工阶段分析结果,控制每个阶段的结构位移量,以实现最终的建筑形态,结合现场试验段的实际测量位移值,修正各施工阶段的预应力值,指导后续单元的施工。
The construction process of dual-direction BSS were introduced in this paper.According to the finite element analysis software ＂MIDAS＂ construction phase analysis results,control every stage of structural displacement quantity,in order to achieve the ultimate architectural form,combined with the practical measurement in the test section of displacement value,correction of construction stage of prestress value,guiding the follow-up unit construction.
