【摘要】 在考虑框架动力特性的基础上，将框架跨度与梁、柱刚度作为设计变量，且约束条件全面考虑了应力、位移、频率和尺寸约束．最后得出在本文条件下，多层框架动力优化计算中框架跨度只需取其下限值的结论．更多还原

【Abstract】 Based on the dynamic property of framework, a dynamic optimized calculation of multistoriedframewouk is made with the span of framework and sit f fness of beams and columns as design variable, andwith stress,displacement, frequency and size constraints as constrained conditions. The calculation made under the above conditions leads to the conclusion that only lower limit is demanded for the span of franlewouk.更多还原
