研究了紧密支撑钢宽翼缘梁的面外性能。这种梁的卸载（破坏）终止了它们的旋转能力，从而终止了它们在塑性设计中的作用。采用不连续屈服理论估计了梁在非弹性范围内的面外行为，并对梁在均匀弯矩作用下的转动能力进行了分析预测。横向支撑间距是梁需要传递的旋转量的函数。计算结果表明，相邻跨的状态对梁的性能有显著的影响。有效长度的概念被用来解释这种影响。
The out-of-plane behavior of closely braced steel wide-flange beams is examined. Unloading (failure) of such beams terminates their rotation capacity and thus their usefulness in plastic design. A theory of discontinuous yielding is used to estimate the out-of-plane behavior in the inelastic range and to provide an analytical prediction of the rotation capacity of beams under uniform moment. The lateral support spacing is found to be a function of the quantity of rotation which the beam is required to deliver. It is shown that the condition of the spans adjacent to the one under consideration has a marked influence on the behavior of the beam. The effective length concept is used to account for this effect.
