［摘要］日照奎山體育中心體育場(chǎng)看臺(tái)采用鋼筋混凝土框架-鋼支撐結(jié)構(gòu)體系，根據(jù)建筑方案要求，看臺(tái)為橢圓形的無(wú)縫結(jié)構(gòu)。采用MIDAS Gen分析了環(huán)形超長(zhǎng)混凝土看臺(tái)的溫度應(yīng)力，并采取補(bǔ)償混凝土、后澆帶和預(yù)應(yīng)力鋼筋等措施控制樓板裂縫。采用ANSYS對(duì)型鋼混凝土巨柱進(jìn)行有限元分析，并采取增大截面、提高含鋼率和混凝土等級(jí)等措施使其滿足罕遇地震作用下抗剪彈性、抗彎不屈服的性能目標(biāo)。最后對(duì)預(yù)制清水混凝土看臺(tái)板的設(shè)計(jì)難點(diǎn)和解決方法進(jìn)行了總結(jié)。

Abstract: The stadium grandstand of Kuishan Sports Center Stadium in Rizhao adopts reinforced concrete frame-steel support structure system. According to the requirements of the architectural scheme, the grandstand is an oval seamless structure. MIDAS Gen was used to analyze the temperature stress of annular super long concrete grandstand, and measures such as compensating concrete, post cast strip and prestressed reinforcement were taken to control floor cracks. ANSYS was used to carry out finite element analysis of steel reinforced concrete giant columns, and measures such as increasing the section, increasing the steel content and concrete grade were taken to meet the performance goal of shear elasticity and bending without yielding under rare earthquake. Finally，the design difficulties and solution methods of precast fair faced concrete viewing platform were summarized. 

Keywords:Kuishan Sports Center in Rizhao； stadium; oval seamless stand； steel reinforced concrete giant column； precast fair faced concrete viewing platform
