| 摘 要： | 通过对Q460高强角钢单边连接的试验研究,指出我国GB50017-2003《钢结构设计规范》和ASCE10-1997《美国输电铁塔设计导则》对宽厚比限值公式的不足之处。根据具体试验数据和对Q460高强角钢单边连接时的局部屈曲性能的研究,推导出单边连接单角钢的实用宽厚比限值公式,用于Q460高强角钢单边连接时压杆设计。

| Abstract: | The unilateral connection of Q460 high-strength angle,the drawback of the GB 50017-2003 and ASCE 10-1997 for the ratio of width to thickness formula was pointed out through the experiment study.According to the specific experiment data and the study of local buckling of the unilateral connection about Q460 high-strength angle,the practical formula of the unilateral connection of the ratio of width to thickness for Q460 high-strength angle was derived,which can used for the unilateral connection bar design of the Q460 high-strength angle. |
