自进入21世纪以来,我国钢结构建筑的发展十分迅速,轻钢结构的发展则更是如火如荼,特别在工业厂房的建设中则更为迅猛。从钢结构制造加施工企业数量的大幅增长就可窥见一斑,如青海省的钢结构制造和施工单位已由原来的十几家一下子发展到现在的200多家。大好形势下,如何因势利导,抓好设计和施工质量,这是当前一个十分迫切的问题。本文拟就轻钢结构的优点、材料选择和设计中的注意点、塑性设计及腹板屈曲后强度的利用等作一概略介绍,利于读者对轻钢结构有一个比较全面的了解。
Since the beginning of the 21st century, the development of steel structures in China has been very rapid, and the development of light steel structures is even more in full swing, especially in the construction of industrial plants. The dramatic increase in the number of steel construction and construction companies can be seen. For example, the steel structure manufacturing and construction units in Qinghai Province have been developed from the original dozen to the current 200. Under a good situation, how to take advantage of the situation and do a good job of design and construction quality is a very pressing issue at present. This article intends to give a brief introduction to the advantages of light steel structures, materials selection and design points of attention, plastic design and the use of post-buckling strength, which will help the reader to have a more comprehensive understanding of the light steel structure.
