用奇异函数分析高层建筑水平加强层的作用

应用奇异函数分析受水平荷载作用的高层建筑中设置加强层和不设加强层的结构，导出水平位移、变形能的函数计算式。由于加强层的位置是随荷载位置变化的，因而这一位置只能限制在一定范围内。提出以顶层单位位移的能耗评价加强层的作用，并指出一些有待进一步探讨的问题。

APPLICATION OF THE SINGULARITY FUNCTION TO THE ANALYSIS OF STRENGTHENED STORIES IN TALL BUILDINGS

By using the singularity function, the writer makes a preliminary structuralanalysis of the tall buildings with or without strengthened stories (SF). Expressionsfor deflections and deformation energies are derived. As optimum lacations of SF isrelative to the load, these locations can only be determined to some scope. Accordingto the refined calculating results,the writer is convinced of that the deformation energy per displacement concerning with the behaviour of SF is important. The writer also points out several problems needed to be fucther analysed.
