| 摘 要： | 根据预应力混凝土结构的计算原理,提出了静载试验的等效荷载计算方法。为了保证数据的准确性,建议预应力混凝土空心板梁抗弯试验中采用2点加载,形成一个较宽的固定弯矩区。介绍了某工程现场静载试验的试验方法、测试手段,并通过对试验数据的分析,对试验梁的受力性能作出了评定。

| Abstract: | According to the calculation principle of the prestressed concrete construction, the calculation method of equivalent load in the static load test of perstressed concrete hollow slabs is put forward in this paper. In order to guarantee exaction of the test, it is suggested that the loading portion should be two points to form a wider section of steady moment. The scheme and measures of practical load test are introduced in the paper. Through analysis of the test, a proper assessment of the quality of test girders is provided. |
