Research on Shaking Table Test Method of Reinforced Concrete Structure Model

为了能够客观评价建筑结构整体抗震性能,通常采用振动台试验适时再现各种地震波对结构的作用过程,从而实现在实验室条件下真实模拟建筑结构抗震,揭示建筑结构地震破坏机理和破坏模式的目的。本研究围绕钢筋混凝土结构模型振动台的相关试验方法,系统梳理了地震基本知识、模型相似理论、模型混凝土、模型安装与传感器布置、试验工况设计、地震激励选择、地震激励输入、数据分析处理等相关研究内容,从而进一步优化了建筑结构模型振动台试验方法,对于深入开展钢筋混凝土结构的抗震性能研究具有重要的参考价值。

In order to objectively evaluate the overall seismic performance of the building structure, the shaking table test used to reproduce the action process of various seismic waves on the structure in a timely manner, whichcan simulate the earthquake resistance of the building structure under laboratory conditions, can reveal the earthquake damage mechanism and failure mode of the building structure.This studyfocused on the shaking table test methods of reinforced concrete structure model, and systematically sorted out the basic knowledge of earthquake, model similarity theory, concrete model, model installation and sensor arrangement, test condition design, seismic excitation selection, seismic excitation input, data analysis and processing, etc., which further optimized the shaking table test method of building structure model. This work has important reference value for in-depth study of the seismic performance and failure mechanism of reinforced concrete structure.
