| 摘 要： | 利用ANSYS有限元程序,考虑几何非线性,对梁柱不等截面的斜腿刚架在梁上作用均布荷载的情况下,进行了大量的荷载—位移全过程分析。分析中选取了七种H形截面,考虑了刚架高度与刚架跨度的比值、刚架柱倾斜角度和横梁坡度三个参数。给出了斜腿刚架柱的计算长度系数和刚架相应的失稳模式。

| Abstract: | Using finite element program of ANSYS, considering geometric nonlinearity, a large number of load-displacement path analysis of tilted column rigid frames with unequal section size of beam and column are conducted under uniformly distributed loads on to the beam. In the analysis, seven kinds of H section are selected, three parameters, such as ratio of height-to-span of the frame, column tilting angle and slope of bean, are also considered. Then proposed the etfective length factors of the columns and the corresponding buckling modes of the frames. |
