摘要
利用有限元软件建立有限元模型,以控制截面弯矩相等效为原则,确定所加荷载大小。结合工程实例,详细阐述了进行静力荷载试验的过程,并分析了试验结果。根据静载试验结果,可判定该工程小箱梁的强度、刚度及抗裂性均满足设计和规范要求。
Establish finite element model with finite element software and take the principle of control the cross section bending moment as equivalent to determine the load value.Combined with the engineering example,the process of the static load test has been introduced in detail and the test result has been analyzed.According to the result of the static load test,the intensity,rigidity and crack resistance of the small box girder shall meet the requirement of the design and specifications.
