摘要]工程實(shí)踐中可以把單波單跨的柱面網(wǎng)殼作為一個結(jié)構(gòu)單體,在橫向和縱向擴(kuò)展形成單波多跨、多波單跨以及多波多跨的整體矩形平面屋蓋系統(tǒng)。通過研究位于多波多跨柱面網(wǎng)殼4個不同區(qū)域的網(wǎng)殼單體,發(fā)現(xiàn)相同區(qū)域內(nèi)的單體受力性能非常接近。并且依據(jù)不同區(qū)域網(wǎng)殼單體的約束情況建立相應(yīng)的簡化模型,通過分析比較簡化模型和整體模型中相應(yīng)單體的受力特性,可以得到二者的受力性能也比較接近。同時應(yīng)用簡化的單體模型考慮網(wǎng)殼桿件的截面選擇和張弦柱面網(wǎng)殼中預(yù)應(yīng)力設(shè)計(jì)的問題,也都能得到比較好的效果。

Abstract: In engineering practices, the mono-wave and mono-span cylindrical lattice shell could be taken as a monomer, which can combine with others to extend to be multi-wave and multi-span cylindrical lattice shells. The mechanical properties of shell monomer in four different parts of the shell integer were studied. It is found that the monomer in the same part holds the similar properties. And four simplified analysis models were created according to the different boundary conditions for different parts. Comparing the properties of simplified models with shell monomers, the two models have the similar properties in the same part. Meanwhile the simplified model could be used to analyze the selection of cross sections for lattice shell bars and design of the pre-stress level for cables, which both could get satisfied results.
Keywords: cylindrical lattice shell; simplified analysis model; selection of cross sections; prestress
