( East China Architecture Design Institution, Shanghai 200002, China)Abstract: The length of Chongqing Grand Theater structure is far more than the provisions about construction joints in the code. To achieve the structuarl design, we use different design and construction methods for different parts of the sturcture suffering variable temperature fuction.
