第二十三章力矩分配法力矩分配法是一种应用很广的实用计算方法,其优点是避免了力法和位移法中解联立方程式的过程。方法简便直观,力矩分配法以求出杆端弯矩为目标。一、本章基本要求;1.了解力矩分配法的基本概念,搞清力矩分配法中固端弯矩、分配系数、传递系数的含义及其计算。2.能较熟练的应用力矩分配法计算连续梁和无侧移刚架,并绘出 M、Q、N 图。对连续梁能由杆端剪力求出支座反力。
CHAPTER TWO TORQUE ASSIGNMENT METHOD The torque distribution method is a widely used practical calculation method. Its advantage is that it avoids the process of solving the simultaneous cubic formula in force method and displacement method. The method is simple and intuitive, and the torque distribution method aims at finding the bending moment of the rod end. First, the basic requirements of this chapter; 1. Understand the basic concepts of the torque distribution method, find out the meaning and calculation of the bending moment, distribution coefficient and transmission coefficient in the torque distribution method. 2. Compatible with the application of torque distribution method to calculate continuous beam and non-lateral rigid frame, and draw M, Q, N charts. For continuous beams, the bearing reaction force can be calculated from the rod end shear force.
