摘要
从基本计算假定的差异出发,对《钢骨混凝土结构设计规程》(YB 9082-2006)和《型钢混凝土组合结构技术规程》(JGJ 138—2001)两本规范中的裂缝宽度计算公式进行比较,并通过实例计算对两种计算方法的差异进行说明,指出《钢骨规程》的计算方法在某些情况下存在着混凝土部分和型钢部分的弯矩分配不符合实际、随配筋增加裂缝宽度不减反增的不合理情况。
Two different methods of calculating the maximum crack width of SRC beam by using Technical Specification of Steel-Reinforced Concrete Structures （YB 9082-2006） and Technical Specification for Steel Reinforced Concrete Composite Structures （JGJ 138-2001） are introduced. Hypotheses of both methods are illustrated and discussed with a calculation example. This article also points out that the bending moment distribution between section steel and RC member do not conform to the hypothesis of JGJ 138-2001 under certain circumstances and this incnnsistence will lead to illozical results.
