［摘要］青島方興展覽廳下部為鋼框架，上部為網(wǎng)架屋蓋。采用SAP2000軟件建立了三種模型進行分析：模型一上部屋蓋結(jié)構(gòu)單獨計算；模型二考慮下部鋼框架和上部屋蓋結(jié)構(gòu)協(xié)同作用的整體計算；模型三在模型二的基礎(chǔ)上考慮了支座高度的整體計算。主要分析了下部結(jié)構(gòu)、支座高度對上部網(wǎng)架的支座反力、跨中及邊跨的桿件內(nèi)力和節(jié)點撓度及自振特性的影響。通過計算結(jié)果對比分析，得到了網(wǎng)架單獨模型、整體模型和考慮支座高度的整體模型的區(qū)別與聯(lián)系，對類似工程設(shè)計具有借鑒意義。

Abstract:Lower part of Fangxing Exhibition in Qingdao is a steel frame structure and upper part is a grid roof structure. Three models were established and analyzed by SAP2000 software. The first model included only the upper roof structure that was calculated separately. The second model considered the overall calculation of the interaction between the lower steel frame and the upper roof structure. The third model considered the overall calculation of height of support based on the second model. The effects of the participation of the substructure and the height of the support were mainly analyzed on the support force of the upper grid, the internal forces and the deflections of the middle span and side span and the natural vibration characteristics. Through the comparison and analysis of the calculation results, the difference and relation between the individual model of the grid, the overall model and the overall model considering height of support were obtained, which could be used as a reference for similar engineering designs.
Keywords:grid structure; cooperative effect; height of support; large span
