［摘要］简要介绍了西宁某温泉游乐中心结构设计，采用有限元软件MIDAS/Gen对主体结构外圈框架模型及与网架结合建成整体模型的计算比对，分析结构整体振型、基底剪力、框架柱与柱间支撑的内力包络值及温度作用下框架柱柱顶位移等指标，确定以单体模型为主、以整体模型校核的结构设计思路。

Abstract: The structure design of a hot spring play center in Xining was briefly introduced. By the comparison between the outer-frame model and the integral model combined with the grid, which were both modeled by the finite element software MIDAS/Gen. Analysis on the indicators including structural vibration modes, base shear, internal force envelope of frame columns and column supports and the top displacement of frame columns under the action of temperature were made, and a design method based on the outer-frame model which would be checked by the integral model determined to take.

Keywords: outer -frame； integral model combined with the grid； self vibration characteristics； action of temperature
