混凝土工程结构振动测试实例及分析

Actual Vibration Test Examples of Concrete Structures and Their Analysis

本文报导了三例混凝土工程结构的振动实测结果以及相应的分析，其中包括装配式混凝土楼盖、混凝土吊车梁和分段拼装的预应力混凝土空心连续板桥．实测结果表明，振动测试方法具有快速、简便等特点，所获取的信息量大于静力试验所获取的信息量，可在结构质量检验以及破损评估中推广应用。

The vibration tests and corresponding analyses of three concrete struc-tures are reported in this paper,which include the assembly RC floor,the RC crane beamand the PC continuous hollow slab bridge. The test results indicate that the vibrationtest gives more information than static test in a faster and simpler way,it can be widelyused in the quality examination and damage evaluation of structures。
