Abstract:
By using total reaction force of jack to denote the uplifting force, and the top average decrease of temporary supporting tower to denote sinking during unloading process, a simulation and calculation method of unloading process of long-span steel structures was proposed. The study results show that the method can effectively eliminate the effects of various factors, such as the deviation of uplifting and sinking amount of each jack, and be convenient for comparing the measured values with the theoretical calculation values. The method can provide scientific references for guiding unloading construction of long-span steel structures.
