前言当杆件横截面尺寸较大,如把高层建筑剪力墙结构作为杆件体系进行近似计算时,需考虑剪切变形。杆件结构由剪切变形引起的位移,在材料力学和结构力学书中早有计算理论和公式。但关于剪切变形的特点,各书多不作详细分析。而在结构计算中,如对结构剪切变形特点了解不够,有可能采用不恰当的计算方法。在这方面,可以举出两个不够合 Foreword When the cross-sectional dimension of the bar is large, such as the approximate calculation of the high-rise building shear wall structure as a bar system, the shear deformation needs to be considered. The displacement of the rod structure caused by shear deformation has long been calculated in theory and formulae in the book of mechanics of materials and structural mechanics. However, with regard to the characteristics of shear deformation, many books are not analyzed in detail. In structural calculations, if the structural shear deformation characteristics are not well understood, it may be possible to use inappropriate calculation methods. In this regard, two examples can be given
