摘要
本文提出用插值法改进传统有限条法的横向局部位移。这种改进过的方法用于高层结构计算中,很好地解决了传统方法遇到的剪力失真问题。该方法较传统有限条法计算精度高,结果可靠,未知量却增加很少。
t In this paper the accuracy of the transverse displacements of the traditional finite strip method is improved by means of interpolation.The problem of shear distortion occurred in calculation of tall building structures by the traditional
finite strip method can be solved satisfactorily .The solution obtained by the new method is more accurate and reliable than that by the traditional method, although the former need few more unknown quantities than the latter.
