建筑技术通讯建筑结构1984年第三期刊载了钢筋混凝土结构设计规范修订组提出的“钢筋混凝土及预应力混凝土受扭构件设计”一文。下面仅就文中有关弯剪扭构件的设计规定,粗浅地谈一点个人的看法。一,由于纯扭构件的强度计算采用了如文中两项和的表达式(6),即考虑了混凝土的抗扭作用,因此,在弯剪扭构件的设计中,至少必须考虑混凝土部分的相关关系,即考虑剪力或扭矩对混凝土抗扭或混凝土抗剪作用的影响。
Building Technology Communication Building structure The third issue of the 1984 edition contained the article “Design of torsion members of reinforced concrete and prestressed concrete” proposed by the revised group of design specifications for reinforced concrete structures. The following is a brief discussion of some personal opinions on the design provisions for bending, shearing and twisting members in the text. First, as the strength calculation of pure torsion members adopts the expression (6) of the two terms in the text, that is, the torsional action of the concrete is taken into account. Therefore, in the design of the bending, shearing and torsion members, at least the correlation of the concrete part must be considered. The relationship is to consider the effect of shear or torque on the torsion resistance of concrete or the shear resistance of concrete.
