对支撑条件和布置方式不是全部由标准计算方法计算的C型冷弯受压构件进行试验和标准分析。前两个试验中采用的构件都具有不对称的C型截面;第三类构件中,两个C型截面通过在翼缘上某一长度处的自钻孔螺栓连接在一起。这些构件上均作用有轴心或者偏心压力。介绍了三种构件的试验布置、性能模式和试验结果,并将试验结果与标准设计结果进行对比,提出了双C型组合截面构件的设计方法。 C-type cold-formed compression members, which are not all calculated by standard calculation methods, are tested and standard-analyzed for supporting conditions and arrangements. The members used in the first two tests had asymmetric C-sections; in the third, two C-sections were connected together by self-drilling bolts at a certain length on the flange. These components are acting on the axis or eccentric pressure. The experimental arrangements, performance modes and test results of the three components are introduced. The test results are compared with the standard design results, and the design method of the double C-section composite members is proposed.
