摘要:
以线性粘滞阻尼器加固剪切型规则框架结构为研究对象,基于能量原理提出阻尼系数正比于层间位移(α+1)次方的分配方式,在此基础上提出了一种基于遗传算法的粘滞阻尼器减震结构优化设计方法。使得中震下结构最大层间位移角小于允许值,以满足"中震不坏"的设计目标,同时令附加总阻尼系数最小,满足经济性要求。以12层规则框架为例,分别采用优化方法和其他三种方案对结构进行减震设计,计算结果表明:基于优化方法进行粘滞阻尼器减震结构优化设计,既能保证结构层间位移角小于限值,又能满足经济性要求。
Abstract:
Shear-type regular frame reinforced by the linear viscous dampers is taken as the research object, and a method, in which the damping coefficient is distributed proportional to the (α + 1)-th power of the inter-story drift, is proposed based on the energy principle. An optimization design method based on genetic algorithm is proposed for the structure with viscous dampers. The maximum inter-story drift angle subjected to the moderate earthquake is controlled within the allowable design value to meet the design goal that "structure will not be damaged in the moderate earthquake", and the additional total damping coefficient is minimized to meet economic requirements. Taken a 12-story regular frame as an example, the proposed optimization method and three other schemes are used to design the structure. The calculation results show that the proposed optimization method not only is able to control the inter-story drift angle within the limit, but also meet the economic requirements.
