单层厂房是工业建筑中有广泛应用,其上作用的荷载种类非常多,且排架柱往往设计为变截面柱,使得排架柱的结构内力计算和内力组合比较麻烦和复杂,很多学生对这部分知识掌握的也不够。本文依照规范给出排架柱的荷载效应组合和最不利内力,全面详细讲解各种内力组合的原则和注意事项,并辅以设计实例,让读者可以更清楚明白的掌握这部分内容。 Single-storey factory buildings are widely used in industrial buildings. There are many types of loads on them, and the columns are often designed as variable cross-section columns. Therefore, the structural internal force calculation and internal force combination of the column-shaped columns are troublesome and complex. Many students This part of knowledge is not enough. In this paper, the load effect combination and the most unfavorable internal force of the racked columns are given in accordance with the rules. The principle and precautions of various internal force combinations are fully explained in detail, and the design examples are provided so that readers can grasp this part more clearly and clearly.
