摘要
讨论了预应力结构在静载试验过程中 ,通过直接测试在试验荷载作用下试验结构的实际应力全量 ,根据结构允许出现的最大应力全量值 ,确定试验结构的承载能力的应力全量静载试验的原理和方法 .结合实例 ,分析了实际试验结构的应力和挠度 。
This paper discusses principle and method of a static loading test based on total stress quantity of prestressed structure, total stress quantity of prestressed structure is tested under loading during static loading test. Its capacity of bearing load is determined according to limit permissible value of it. Instance of static loading test of 30m T beam, actual stress and deflection of structure tested is analyzed and capacity of bearing load for structure tested is evaluated.
