手算与PKPM内力对比及电算正确性研究

ombined with the practical project, this paper introduces the hand-calculation method and process of the internal force under the vertical dead load and the horizontal seismic load of a reinforced concrete frame residential structure. Horizontal seismic load calculation using base shear method, internal force calculation under the vertical dead load and the horizontal seismic load respectively using second moment distribution method and d-value method. It obtained that load calculation method, internal force calculation method and human factors are the reasons for differences beween results by contrasting hand-calculation with PKPM computerization. Then, according to some problems that the PKPM results may occur errors and whether results can be used directly to construction drawing design, this paper puts forward reasons for mistakes of PKPM computerization and the accuracy of judgment basis of PKPM computerization.
