环境因素对混凝土结构特征参数影响的试验分析

Test Analysis of Environmental Effect on Concrete Structural Feature Parameters

摘要:

基于模型试验分析了环境因素对混凝土结构特征参数的影响,包括环境温度和环境湿度.首先对试验环境进行了介绍,接着基于混凝土连续梁模型分析了环境温度对结构模态频率的影响,尤其是结冰时的非线性效应.最后基于混凝土试块分析了环境湿度对结构质量的影响,发现具有明显的时间滞后效应.

Abstract:

An experiment was made to investigate the environmental effect,including environmental temperature and humidity,on concrete structural feature parameters.First,the experiment condition was introduced.Then,based on a concrete continuous supported beam model,an analysis was made of the environmental temperature effect on structural modal frequencies,especially the nonlinear effect of freezing.Finally,the environmental humidity effect on structural mass was validated by a concrete block experiment.Results show that the humidity is of an obvious timelag effect on structural mass.
