摘要
本文以某三层框架结构为例,因怀疑预应力钢筋混凝土双T板的混凝土强度,为保证结构工程的安全使用,考虑最不利因素,选择强度最低的双T板,采用分级加载方式,在双T板原位进行了安全性静载检验,测量双T板的荷载、挠度、残余应变等指标,与理论形成对比,并对试验结果与理论结果进行讨论和分析,为后续类似工程提供参考。
This paper took a three-story frame structure as an example,because of the doubt of the concrete strength of the prestressed reinforced concrete double T-slab,in order to ensure the safe use of the structural engineering,considering the most unfavorable factors,the double T-slab with the lowest strength is selected and the safety static load test is carried out in the original position of the double T-slab by using the graded loading method,and the load,deflection,residual strain and other indicators of the double T-slab are measured to provide reference for similar projects in the future,the paper discusses and analyzes the test results and theoretical results.
