| Abstract: | 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. |
