摘要
探讨高层钢筋砼框架结构布置与梁柱截面尺寸整体优化设计问题,推导了数学优化近似计算公式.利用该近似计算公式,可简捷地计算出满足侧移限值等约束条件的框架梁柱截面尺寸,检验结构方案的合理性;并通过算例说明利用该方法可加速结构设计,提高设计质量.
The issues about the structural layout of high-rise reinforced concrete frames and beam-column frame section sizes were discussed and the approximate formula for their mathematical optimization was deduced. By the approximate formula thus derived, the rationality of the structural layout may be inspected, and the optimum section sizes of a beam-column frame can be calculated to satisfy constraint conditions such as drift limits. An illustrative example demonstrated that this method can be used to facilitate the design work and improve the design.
