［摘要］采用局部加载方式对某一新建的钢框架结构进行使用性能检验，对检验方法和过程进行系统的设计。选择了4个构件进行使用性能检验，依据理想传力路径，在构件承载区域进行局部均匀重物加载，模拟结构理想检验荷载。检验中主要对构件在局部加载作用下的变形以及应变的变化进行精密测量，通过对检验结果的分析和探讨，证明局部加载具有较高的可靠性。总结了局部加载条件下使用性能检验的方法，对此类结构的使用性能检验具有较高的实用参考价值。

Abstract:Local loading was used in applicable performance of a steel frame structure and the test method and process were designed systematically. Four components were selected in local loading according to practical situation and ideal testing load was simulated by uniform weight drop. It is proved that local loading has high reliability based on the results of deformation and strain. Applicable performance method of local loading is summarized which has higher practical reference value for similar structures.

Keywords:local loading; steel frame structure; applicable performance; inspection method
