前言钢管结构是由圆钢管或矩形(含方形)钢管制作加工而成的结构。钢管结构可以是独立的梁、柱式构件,亦可以组合成为格构式构件。在格构式构件中,也可用工字钢为主杆,以钢管为支杆。总之,其使用范围是广泛的。而钢管材料又有热加工管和冷成型管之分,随着我国钢材品种的增多,管材供应将日趋好转。由于钢管结构在力学、防腐性能和经济指标上的优越性已逐渐为人们所认识。钢管结构在工业与民用建筑中的应用已日益广
Introduction Steel pipe structure is made of round steel pipe or rectangular (including square) steel pipe made of processed structure. The steel pipe structure may be an independent beam or column member, or may be combined into a lattice member. In the lattice structure member, the I-beam can also be used as the main rod and the steel tube as the support rod. In short, its scope of use is extensive. The steel pipe material is divided into hot processing pipe and cold forming pipe. With the increase of steel products in China, pipe supply will gradually improve. The advantages of steel structure in mechanics, anti-corrosion performance and economic indicators have been gradually recognized by people. The application of steel pipe structures in industrial and civil buildings has become increasingly widespread
