摘要:
为研究早龄期预制叠合剪力墙的收缩变形特性,制作了一片小尺寸预制叠合剪力墙试件并进行试验观测.通过对剪力墙内部自干燥和湿度扩散形成的湿度场计算,基于GL2000收缩模型,对预制叠合剪力墙收缩应变进行了计算分析,计算结果与试验结果吻合良好.比较了墙厚和外部环境湿度条件参数对预制叠合剪力墙收缩变形的影响,并对暴露在不同环境湿度条件下的早龄期预制叠合剪力墙开裂风险进行了预测.
Abstract:
To investigate the shrinkage behavior of precast superimposed reinforced concrete shear wall(SRCSW)at early ages, one SRCSW specimen in small size was constructed and tested. The moisture field of the specimen developed by self-desiccation and moisture diffusion was analyzed. According to the GL2000 theory, the shrinkage response was calculated and the analytical results match well with the test results. Lastly, the influence of wall thickness and the environmental humidity on the shrinkage behavior was discussed and the cracking potential of SRCSW under different environmental humidity conditions was predicted.
