摘要
预应力索张拉控制技术是张弦梁结构成型的关键,采用有限元技术对无安装支撑的中小型张弦梁预应力索进行施工模拟分析,得到初始状态至荷载状态各索具控制应力及对应变形(应力)值,计算结果指导实际施工,实测值满足结构要求,验证方案合理有效。
Prstressed cable tension control is a key technique for forming beam string structure. In this paper, we use FEM to simulate the construction of small and medium sized beam string prestressed cable without supported, and obtain the control stress and strain of each cable from initial stage to load stage, then using the calculation results to guide practical construction, the measured values meet the structural requirements, the scheme is verified reasonable and effective
