摘要: 西安奥体中心体育馆看台的抗侧力体系采用钢筋混凝土框架￣剪力墙结构，阶梯形看台板采用预制清水混凝土板。 体育馆外围周长达 530m，为超长结构。 采用 SAP2000 软件分析了预制清水混凝土看台板的简化模拟方法及其对整体结构的受力影响；分析了环形结构内环直径大小对温度应力的影响，比较了环形结构和长边长度分别等于环形结构周长和直径的矩形结构三者之间的温度应力差别；针对看台超长的特点，对混凝土看台进行了温度应力分析，分析时考虑了混凝土收缩、徐变以及基础水平刚度等因素。 各项分析结果表明，预制清水混凝土看台板主要影响斜向看台的环向受力，对斜向看台径向受力的影响可以忽略；温度作用下，环形结构楼板拉应力小于长边长度等于环形结构周长的矩形结构，与长边长度等于环形结构直径的矩形结构比较接近。

Abstract: The lateral resisting system of the stand of Xi′ an Olympic Sports Center Gymnasium adopts the reinforcedconcrete frame￣shearwall structure， and the step￣like stand slab adopts the prefabricated fair￣faced concrete slab. Thelength of the outermost line of the gymnasium reaches 530m， which is a super￣long structure. The SAP2000 software wasused to analyze the influence of the simplified simulation method of prefabricated fair￣faced concrete stand slab on the wholestructure. The influence of the inner diameter of the annular structure on the temperature stress was analyzed， and thetemperature stress differences between the annular structure and the rectangular structures whose long side length wasrespectively equal to the circumference and diameter of the annular structure were compared. According to thecharacteristics of super￣long stand， the thermal stress of the concrete stand slab was analyzed considering the factors ofconcrete shrinkage， creep and horizontal stiffness of foundation. Various analysis results show that the prefabricatedfair￣faced concrete stand slab mainly affects the circumferential force of the oblique stand， and the influence on the radialforce of the oblique stand can be ignored；under the action of temperature， the tensile stress of the ring structure slab is lessthan the rectangular structure slab with length of the long side equal to the ring perimeter of structure and is close to therectangular structure whose long side length is equal to the diameter of the ring structure.
