摘要
国瑞·西安金融中心施工中,为改善钢板-混凝土组合剪力墙裂缝防控效果,对原材料选择、配合比设计、钢板墙构造、施工工艺及养护措施进行研究,制订了混凝土防裂措施,设计了足尺模型,通过研究组合剪力墙的温度场、早期应力、应变发展趋势及规律,确定了防止剪力墙裂缝的方法,裂缝控制效果显著。
During construction of Glory Xi＇an Financial Center, raw material selection, mixing proportion design, steel plate wall structure, construction process and curing measure were studied to improve the crack prevention and control effect of steel plate and concrete composite shear wall, establish the concrete cracking control measure and design the full scale model. The method for prevention of shear wall crack was determined after study on the temperature field of shear wall, early- age stress, strain development trend and law, realizing effective crack control.
