Abstract：
Before construction of Glory Xi'an Financial Center, a full scale model of 11?m×1.7?m×2.2?m (length×thickness×height) 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.
