一、前言魏琏同志用不均衡力矩及侧力同时傅播,最后进行一次分配的方法来分析跨变刚构,确使该类刚构的分析达到极其精简的地步。此法既不须进行侧移叠加,又不须进行侧移修正,且不用解算任何联立方程,最适合于多种荷载下之分析,此等优点,实非已往的其他方法所及,值得大家学习和推广。本文之目的,在于将不均衡力矩及侧力傅播法推广用于有侧移之直捍刚构的分析上,不论刚构为单层或多层,等截面或变截面,简单刚构或复式刚构,以及不论其引起侧移之来源为水平力或不对称之垂直力,均可应用本法直接分析,特别对于多层复式刚构的分析,应用本法,不但免去了多种侧移叠加的手续,并免去了用联立方程求解侧移的步骤,致使此类刚构的精确分析更为直接和简便。
I. INTRODUCTION Comrade Wei Wei used simultaneous unbalanced moments and lateral forces for the simultaneous sowing, and finally performed a distribution method to analyze the cross-varying rigid frame structure, so that the analysis of this type of rigid frame structure was extremely streamlined. This method does not require lateral shift superposition, and does not require lateral shift correction, and does not solve any simultaneous equations. It is most suitable for analysis under various loads, and these advantages are in fact not achieved by other methods. It is worth learning and promoting. The purpose of this paper is to generalize the unbalanced moments and lateral force fuction propagation methods for the analysis of straight-river rigid frame structures with lateral displacements, whether rigid structures are single or multiple layers, equal or variable cross sections, simple rigid structures or Duplex rigid frame, and whether it causes horizontal force or vertical force of asymmetry, can be directly analyzed by this method. Especially for the analysis of multi-layer composite rigid frame, applying this method not only eliminates a variety of The procedure of stacking is shifted laterally, and the step of solving the lateral shift with simultaneous equations is eliminated, so that the accurate analysis of such rigid frames is more direct and simple.
