在工业房屋承重结构设计中,目前大都采用钢筋混凝土工形断面的柱,这是因为工形断面的柱比较经济合理的缘故。但是关于工形柱的计算资料,现在还很少见。因此笔者根据工作中的体会,参照苏联“钢筋混凝土结构构件断面计算规程”和颜景田译“单层工业房屋钢筋混凝土柱”二书,写成这篇文章,供大家参考。由于工业厂房的柱多采用对称配筋,所以本文也相应地只谈对称配筋的计算。一一般计算公式一般计算公式可依下列两种情况考虑:1)当 d<0.1h 时,计算中不考虑翼板,与宽度为b_1的矩形断面的计算一样。
In the design of load-bearing structures for industrial buildings, pillars with reinforced concrete sections are mostly used today because of the economical and reasonable nature of columns with I-shaped sections. However, computational data on I-pillars are still rare. Therefore, according to the experience of the work, the author refers to the Soviet Union’s “Calculation Rules for the Sections of Reinforced Concrete Structural Members” and Yan Jingtian’s translation of “Single-story Industrial Building Reinforced Concrete Columns,” and wrote this article for your reference. Because the column of the industrial plant uses symmetrical reinforcement, this article will only discuss the calculation of symmetrical reinforcement. A general calculation formula The general calculation formula can be considered in the following two cases: 1) When d < 0.1h, the wing plate is not considered in the calculation, and it is the same as the calculation of the rectangular section with width b_1.
