摘　　要：钢结构稳定性能是决定其承载力的一个重要因素,因而稳定问题是钢结构设计中的不容忽视的重要问题。对于压弯构件,如果设计或构造措施上处理不当,可能会使钢结构出现整体失稳或局部失稳,导致结构破坏,因此分析和探讨钢结构的稳定性问题在工程实践中有着重要意义。本文研究钢结构单轴对称压弯构件在横向均布荷载和集中荷载作用下简支梁的弯曲性能,分析了简支钢梁在两种荷载作用下的内力和变形分析,为钢结构稳定性设计提供一些设计参考。Stability of steel structure is an important factor to determine its bearing capacity, which can not be ignored in the design of steel structure. Improper design or structural measures of beam-columns may lead to overall or local instability of steel structure, resulting in structural damage, so it is of great importance to analyze and discuss the stability problems of steel structure in engineering practice. This paper studied the flexural properties of the beam column of steel structure uniaxial symmetry under the influence of lateral load and concentrated load and analyzed the internal force of steel beams in almost two kinds of loads and deformation so as to provide some reference for the stability design of steel structures.
