给出了屈曲约束支撑框架的设计方法。该程序采用了非线性时程分析和优化。并将计算结果与常用的等效侧向力法进行了比较。计算结果被用来开发设计曲线和公式，以便快速确定每层屈曲约束支撑的横截面面积。一个有趣的结果是，对于所研究的大多数情况，各层之间的最佳面积变化几乎是线性的。这一结果不能通过等效侧向力法预测，只能通过优化和非线性时程分析才能发现。
A procedure for the design of buckling-restrained braced frames is presented. The procedure uses nonlinear time history analysis and optimization. Results from this procedure are compared to those from the commonly used equivalent lateral force procedure. Results are used to develop design curves and formulas for rapid determination of cross-sectional areas for buckling-restrained braces in each story. One interesting result is that the optimum variation of area from story to story is nearly linear for most cases studied. This result is not predicted by the equivalent lateral force procedure, and can only be discovered through optimization and nonlinear time history analysis.
