【摘要】 通过对钢结构承重梁柱所用的三种型材(H型钢、方矩形管和圆管)各种性能的对比和分析,认为方矩形钢管是钢结构中最佳的立柱材料。结合国内外现状,指出钢结构方矩形钢管在我国还有一定的发展空间。同时简单介绍了方矩形钢管的三种生产方法以及生产时可能存在的问题,并给出了解决办法。更多还原

【Abstract】 It is considered that rectangular steel pipes is the best support column among the steel structure through the compare and analysis of each property of two profiled steels (i. e. H profiled bar,rectangular steel pipe and round steel pipe) which are used in steel structure bearing beam and column. Combined with the actuality of China and abroad, it is thought of rectangular steel pipes for steel structure has certain grow space in China. The three kinds manufacturing for rectangular pipes is briefly introduced. Any possible existed problem during manufacture of rectangular pipes is analyzed and the solve method is given.更多还原
