无论钢结构、混凝土结构或砌体结构、木结构等,施工中常常会遇到稳定性的验算问题。一个结构物或构件,在施工过程中或施工完毕后,由于某些因素的影响,往往会发生失稳现象,引起工程事故,甚至造成人员伤亡。因此,对稳定性的验算应给予足够的重视。对于某些受力构件,计算中除了对材料强度进行校核外,必要时,对其稳定性也需加以验算,并应采取相应的措施来确保结构安全。 Regardless of steel structures, concrete structures or masonry structures, wood structures, and so on, stability checking problems are often encountered in construction. A structure or component, in the construction process or after the completion of the construction, due to the influence of certain factors, often cause instability phenomenon, causing engineering accidents, and even cause casualties. Therefore, the stability check should be given enough attention. For some stressed members, besides checking the strength of the material, the stability must also be checked when necessary, and corresponding measures should be taken to ensure the structural safety.
