摘要
某档案馆由于使用功能的改变,导致结构承受的荷载性质发生了改变,因此对其进行了加固。为了检验加固的效果,按照现行规范的有关规定对采用增大截面法加固后的某次梁进行原位荷载试验。根据结构在各级荷载作用下的挠度变形与裂缝开展情况,判断结构是否满足相关规范要求以及评价结构的加固效果;同时将挠度与裂缝宽度的实测值与理论值进行比较。
The load property that the structure bears is changed due to the changed function,so we need to strengthen the archives.We should take a situ load test about secondary beam in accordance with the relevant provisions of the existing norms on the use of increasing a beam＇s section.According to the deflection deformation and fracture of the structure under the loads at all levels,to determine whether the structure meet the relevant regulatory requirements as well as evaluating the structure of the reinforcement effect and compare the measured values with the theoretical value of deflection and crack width.
