【摘要】 依据温特（Ｇ．Ｗｉｎｔｅｒ）有效宽度公式和统一法则方法，给出了矩形钢管全截面有效时的ｂ／ｔ、ｈ／ｔ限值，并在此基础上给出了换形钢管混凝土构件钢板件的限值，可供设计和制造者参考。更多还原

【Abstract】 In this paper, the limitation for b/t、 h/t ratios of steel rectangular hollow sections which are whole effective is presented by using Winter’s effective equations and trifled approach. Also the limitation of steel section plates is given for the steel rectangular hollow section filled with concrete. All the limitations presented here are valuable for the designers and manufacturers.更多还原
