摘要:拟建体育场馆的楼盖采用蜂窝型U型钢-砼组合蜂窝型空腹夹层板形式,跨度为39.26m,对楼盖动力特性进行了建模分析。表明U型钢-混组合蜂窝型空腹板楼盖整体性较好,楼盖刚度分布匀称;楼盖的基频值满足国内规范要求;分析了上下肋梁对基频的影响,结果表明,下肋梁高度增加对楼盖刚度提高更有效。
Abstract: The building cover of the proposed stadlium adopts the honeycomb lU-shaped steel-concrete combination honeycomb fastingsandwich plate with a span of 39.26m, and the dynamic characteristics of the building cover are modleled and analyzed. The results showthat the U-shaped steel-mixed honeycomb type fasting plate building cover has good inlegrity, and the rigidity distribution of the buildingcover is uniform.The fundamental frequency value of the building cover meets the requirements of domestic norms. The inluence of upperand lower rib beams on the fundamental frequency was analyzedl, and the results showed that the increase of the height of the lower ribbeam was more effective for improving the rigidity of the roof.
