中文摘要：
济南奥体中心莲花体育馆弦支穹顶结构为目前世界上跨度最大的肋环型布索形式的球面弦支体系.弦支穹顶结构为一新型的大跨度空间结构体系,该体系在正常使用过程和施工张拉过程中的温度作用影响不容忽视.本文采用单独钢结构模型和整体结构模型两种计算分析模型对温度作用的影响做了初步分析.钢筋混凝土构件和钢结构构件(包括索)由于材料导热系数、热膨胀系数、截面尺寸及构件体积等的差别其中面的温度时程变化并不是同步同幅的,本文参考大体积混凝土的温度梯度变化模式、济南当地的气象统计资料及本工程结构健康检测的实测数据对莲花穹顶的温度效应做了对比分析并给出了初步结论和建议.
英文摘要：
The suspen-dome of the gymnasium of Ji nan Olympic Center is the largest spherical one in the world at present.Suspen-dome is a novel system of large-span space structure.Temperature effects on the structural performance must be taken into account for the normal use.An independent steel structure model and the integral structure model including the lower concrete supporting system are employed to study this problem.The concerned temperature acts on the concrete members and steel members(including tensioned ...
