摘要
某工程利用框架结构特性,对托梁及待加固柱先利用体外索进行卸载,对托梁实施预应力加固处理以及增大柱子截面。针对高层结构托梁拔柱工程进行简化建模以提高非线性计算效率。
According to the character of the frame＇s structure, The external cable is used to unload the beam and the column, whick are needed reinforcement in this project. The joist is strengthened by pre-stressed steel and the pillar＇s section is increased. In order to enhance the efficiency of nonlinear computation ,the model is simplified in the project of supporting beam and removing column related to high structure.The practice indicates that, the unloading and its computation are reliable.
