摘要
以确定建筑物变形观测的允许变形值为目标,通过将建筑物的变形观测误差作为等效荷载纳入荷载组合,运用有限单元理论,求得最不利荷载组合值下的极限变形值,从建筑物上部结构受力特点出发,介绍建筑物变形观测精度指标的确定方法。
By taking the building deformation observation error as equivalent loads in the finite element theory, this paper focuses on the identification of a building deformation observation allowed. The most unfavorable load combination is used to obtain the limit value of deformation values. By analysis of upper structure stress characteristics of buildings, the exact method of determining building deformation observation accuracy index is given.
