摘　　要：提出了蒙皮支撑钢构件静力工作性能的非线性有限元分析方法，用该方法分析了蒙皮支撑梁和蒙皮支撑柱的基本受力性能，并考虑了多种因素对蒙皮支撑构件性能的影响。分析结果表明，蒙皮对构件的侧向支撑及扭转约束作用可以大大改善构件的静力性能并提高构件的承载力。The finite element method for geometric nonlinear analys is of diaphragm braced steel members under static loading is presented in this paper. Using this method, the basic behavior of diaphragm braced beams and columns is investigated and several factors affecting the member behavior are taken into account. The research results indicate that the diaphragm bracing and rotation restraint can improve the behavior of steel members obviously and increase their load carrying capacity.
