摘要
国瑞·西安金融中心工程施工前,为研究钢板-混凝土组合剪力墙的早期混凝土应变规律,设计了长11 m,厚1.7 m,高2.2 m的足尺模型,通过试验监测得到了组合剪力墙的早期应变发展趋势和分布规律,发现温度是混凝土产生早期应变最主要的因素,温度应变约占早期混凝土总应变的80%以上,混凝土浇筑后18 d左右混凝土应变趋于稳定。
Before construction of Glory Xi'an Financial Center, a full scale model of llmxl.7mx2.2m (lengthxthicknessxheight) was designed to study the early-age concrete strain law of steel plate and concrete composite shear wall. Early-age strain development trend and distribution law of the composite wall were obtained. It was found that temperature is the most important factor influencing early-age strain of concrete. Temperature strain takes about more than 80% of the total strain of concrete at early age and the concrete strain becomes stable about 18 days after concrete grouting.
