张弦梁结构实测和数值计算分析

On beam string structure's survey and numerical calculating analysis

采用实验和数值分析两种方法,分别对实际张弦梁进行现场实测和理论研究,在实测中,主要是监控施工中张弦梁的预应力大小,并测量结构在施加预应力前后的变形情况,重点研究该结构的预应力合理取值,并采用时程分析方法,研究整体结构的地震响应。

The paper, adopting the experimental and numerical methods, has the field survey and theory research on the beam string structure, indicates the prestress of the beam string structure is the main aim for the supervision construction, and the deformation situations before and after the implementation of the prestress of the structure is measured in the factual survey, and mainly researches the reasonable value for the structural prestress of the structure, and the time history analysis is used to research the earthquake response of the whole structure.
