［摘要］冷彎薄壁型鋼組合樓蓋在使用過程中既要承擔(dān)上部樓層傳來的豎向荷載并且傳遞風(fēng)荷載及地震力至剪力墻，同時要滿足舒適度指標(biāo)，因此組合樓蓋必須具備良好的承載能力、剛度及振動性能。結(jié)合國內(nèi)外具有代表性的冷彎薄壁型鋼組合樓蓋受力性能的研究進(jìn)展，從承載力研究、剛度研究和振動性能研究三個方面總結(jié)，分析組合樓蓋類型和不同樓蓋構(gòu)造措施對組合樓蓋受力性能的影響，綜合國內(nèi)外理論分析成果，總結(jié)不同類型的組合樓蓋抗彎承載力和平面內(nèi)（外）剛度的計算方法及振動舒適度設(shè)計標(biāo)準(zhǔn)，指出冷彎薄壁型鋼組合樓蓋現(xiàn)有設(shè)計方法和理論體系的不足，為編制國家或行業(yè)設(shè)計標(biāo)準(zhǔn)提供可靠依據(jù)，以期推動冷彎薄壁型鋼結(jié)構(gòu)住宅在中國的發(fā)展應(yīng)用。［關(guān)鍵詞］冷彎薄壁型鋼; 組合樓蓋; 承載能力; 剛度; 振動性能中圖分類號：TU398.9 文獻(xiàn)標(biāo)識碼：A 文章編號：1002-848X(2016)12-0088-09
Literature review of mechanical performance of cold-formed thinwalled steel composite floorsGuan Yu, Song Kai, Shi Yu（School of Civil Engineering, Chang'an University, Xi'an 710061, China）Abstract: In the process of use, cold-formed thin-walled steel composite floor should undertake the upper floor vertical load and transfer wind load and seismic force to the shear wall; in addition, the composite floor should meet the comfort index. So the composite floor must have good bearing capacity, stiffness and vibration performance. Combined with domestic and foreign representative research progress of mechanical performance on cold-formed thin-walled steel composite floor, research progress was summarized from three aspects of bearing capacity, stiffness and vibration performance. The influences of different combination floor types and different floor structure measures on mechanical performance of the composite floor were analyzed. Combined with domestic and foreign theoretical analysis results, the flexural bearing capacity calculation method and the in-plane or out-of-plane stiffness calculation method were summarized as well as vibration comfort design standards of different composite floor types. In addition, it pointed out the shortage of the existing design method and theory system for cold-formed thin-walled steel composite floor, providing a reliable basis for the compilation of national or industry design standards to promote the development and application of the cold-formed thin-walled steel structural housing in China.Keywords: cold-formed thin-walled steel; composite floor; bearing capacity; stiffness; vibration performance
