结构性能定义 压曲抗力 构件在不出现压曲的情况下所能承受的力或弯矩的限值。 梁的计算长度 梁在相邻抗侧向弯扭压曲约束点之间的长度，乘以一个系数，该系数用以考虑实际约束效应与两端完全受扭转约束简支梁之间的差别。 受压构件的计算长度 柱在相邻抗绕某一轴线压曲的侧向约束点之间的长度，乘以一个系数，该系数用以考虑实际约束效应与两端铰接柱之间的差别。 弹性分析 不考虑连续构件或框架中因塑性铰转动而导致弯矩重新分配的结构分析。 弹性临界荷载 理想构件或结构发生弹性不稳定时所承受的荷载。 整体缺陷 结构体系的几何不垂直。 整体稳定性 整个结构对压曲、倾覆、上撔以及滑动的稳定性。 不稳定性 由于丧失刚度而不能够继续承载的现象。 梁的侧向约束 防止梁受压翼缘侧向移动的约束。 受压构件的侧向约束 防止构件在指定平面内侧向移动的约束。 局部稳定性 构件或构件的某一部份对压曲的稳定性。 构件缺陷 结构构件的内在弯曲。 7塑性分析 考虑连续构件或框架中因塑性铰转动而导致弯矩重新分配的结构分析。 塑性荷载因子 形成塑性铰机构时，每一项设计荷载需要增加的比例。 塑性弯矩 构件横截面在应力重新分配后的弯矩承载力。 二阶分析 包含结构平衡或，在首个塑性铰形成之前，荷载跟挠度关系，以及考虑初始缺陷影响的结构分析方法。 细长比 有效长度与回转半径的比例。 稳定性 在压曲损坏或丧失静力平衡前的承载力。
