钢管混凝土框架结构的设计与探讨

Design and Discussion of concrete filled steel tubular frame structure

钢管混凝土框架结构承载力高,抗震性能好,施工方便,在工程中的应用日益广泛。钢管混凝土柱具有很强的抗压能力,柱截面可以大大缩小。钢骨混凝土梁具有较高的抗弯承载力,适用于大跨度结构。梁柱节点起着重要作用,它直接影响整个结构的刚度。本文结合工程实例,从以上三方面,探讨了钢管混凝土框架结构的设计要点,构造措施及计算方法,可供同类结构参考。

Due to the high strength,good anti-seismic property and easy construction,the concrete filled steel tubular(CFST) frame structural system are wide-ranging applied in engineering.CFST column has much high compress strength,therefore its size can be minimized largely.Because of the higher flexural capacity of the steel reinforced concrete(SRC) beam,the problem of long-span has been well solved.Beam-column joint is important and has direct influence on the rigidity of the structure.Through some engineering pra...
