前言本文从结构中一个微段的相对变位或从结构的支座沉陷对所求结构变位的影响出发,过用机动法作结构内力或反力影响线的转换,可以推导出求结构变位的公式。由于本文所建立的方法是从研究对结构变位的影响出发,故称之为“影响法”。
Preface In this paper, starting from the relative displacement of a micro-section in the structure or from the influence of structural subsidence on the structural displacement, using the method of maneuver for the transformation of the influence of structural internal force or reaction force, we can deduce that the structural change Bit formula. Since the method established in this paper is based on the study of the effect of structural displacement, it is called “influence method”.
