关于修改港工钢筋混凝土规范小偏心受压构件正截面强度计算的建议

REVISIONS ON NORMAL SECTION STRENGTH OF SMALL ECCENTRIC COMPRESSION MEMBERS IN DESIGN CODE OF PORT ENGINEERING R. C. STRUCTURES

本文提出在小偏心受压构件正截面强度计算中，取消弯曲抗压强度ｆｃｍ（Ｒｗ），采用轴心抗压强度ｆｃ，这与构件的实际破坏形态相符。对小偏心受压构件正截面强度计算提出了设计建议。特别是对工程上大量应用的矩形截面对称配筋小偏压构件提示了简捷的设计方法，与以往的近似计算方法相比具有物理概念明确，精度高，方法简捷的特点。

In the formulas proposed in this paper for calculating normal section strength of small eccentric compression memhers, anial compressive strength“fc” is adopted instead of flexural strength“fm”to agree with the damage pattern of members. Suggestions are presented for calculating normal section strength of small eccentric compressive members. A new calculation method is given for small eccentric compressive members with symmetrical reinforcement which are extensively used in engineering.Compared with the approximate method used before, this method is simple, accurate and definite in concept.
