［摘要］隨著國民經(jīng)濟的發(fā)展和建筑技術(shù)的進步，大跨度懸挑鋼結(jié)構(gòu)工程的應(yīng)用越來越多。而高抗震設(shè)防烈度下的大跨度結(jié)構(gòu)的設(shè)計一直是結(jié)構(gòu)工程師關(guān)心和探討的課題。通過PKPM軟件對箱形懸挑鋼結(jié)構(gòu)平臺進行建模分析，結(jié)構(gòu)的應(yīng)力比、撓度、位移等計算指標的計算結(jié)果滿足規(guī)范要求。此外，抗震構(gòu)造措施的進一步加強，確保了該結(jié)構(gòu)設(shè)計的安全與可靠。

Abstract: With the development of the national economy and the progress of architectural technology, more and more steel structure engineering of long span suspension are applied. That the engineers always care about and discuss is the design of large span structure under seismic fortification intensity. The model was built by PKPM software to analyze the box type cantilever steel platform, and calculation results of calculation parameters including the stress ratio, deflection, displacement, and so on, can meet the requirements of specification. In addition, the anti-seismic measures were adopted to ensure the safety and reliability of the structure design.
Keywords: overhanging steel structure; box; deflection; displacement
