摘　　要：为研究强迫位移下钢结构压弯构件的强度,推导了构件在位移一定时材料强度和截面尺寸关系公式,结果表明压弯构件在位移一定时,需要适当减小截面尺寸来满足强度要求。最后以某电厂烟囱为例,采用ANSYS软件进行有限元数值模拟分析,通过结果对比验证了文中理论公式的正确性。In order to investigate the strength checking conditions of the steel structural members with bending and axial compression subjected to known enforced support displacements, the formula of the relationship between the material strength and the sectional dimensions subjected to known enforced support displacements was derived. The result shows that under the enforced support displacements, the sectional dimension needs to be reduced properly to meet the strength requirements. A case study of a chimney of a power plant was taken as an example to validate the conclusions, in which, ANSYS software was employed to carry out finite element numerical simulation analysis. Finally, the comparison of results defensed the formula proposed in the paper.
