［摘要］異形網(wǎng)架在進(jìn)行結(jié)構(gòu)設(shè)計(jì)時(shí)通常采用鋼網(wǎng)架屋蓋與下部結(jié)構(gòu)分開(kāi)建模的方式，按此種方法計(jì)算得到的結(jié)果與整體建模的計(jì)算結(jié)果相比差別較大。基于此，為探究不同建模方法在異形網(wǎng)架設(shè)計(jì)中的準(zhǔn)確性及適用性，以南京工業(yè)大學(xué)禮堂結(jié)構(gòu)為例，采用SAP2000軟件，分別建立獨(dú)立計(jì)算模型、整體計(jì)算模型及鋼梁等代網(wǎng)架整體計(jì)算模型進(jìn)行抗震分析計(jì)算。計(jì)算結(jié)果表明，采用整體計(jì)算模型的計(jì)算結(jié)果，能夠較全面地反映網(wǎng)架的受力狀態(tài)及變形情況。

Abstract: In the structural design of special-shaped grids, the roof of steel grids and substructure are usually modeled separately, and the result calculated by this method is quite different from the result calculated by the overall modeling. Based on this, in order to explore the accuracy and applicability of different modeling methods in the design of special-shaped grid structure, taking the auditorium structure of Nanjing Tech University as an example, SAP2000 software was adopted to establish independent calculation model, overall calculation model and substitute grid overall calculation for example steel beams for seismic analysis and calculation. The calculation results show that the calculation results using the overall calculation model can reflect the stress and deformation of the grid in a more comprehensive way.  

Keywords:special-shaped grid； independent calculation model； overall calculation model； substitute grid overall calculation for example steel beam； seismic performance
