摘要
消能减震结构可以根据不同附加等效阻尼比确定地震影响系数,因此,确定合理的阻尼比成为消能减震结构设计的关键.首先对比中、美、日3国计算方法的差异,然后对消能减震结构的等效阻尼比计算方法进行研究,最后根据日本消能减震结构阻尼比计算的思路,提出更为合理精确的计算公式,为该类结构的设计提供理论依据.
Earthquake influence coefficient of energy dissipation structure can be determined by different additional equivalent damping ratios. So, the key to energy dissipation structure design is to choose a appropriate damping ratio. Firstly, the difference of calculation methods among China, America and Japan was compared. Then, the calculation method for equivalent damping ratio of energy dissipation structure was studied. Finally, based on calculation process of the damping ratio of the energy dissipation struc- ture, the much more appropriate and precise calculation formula was provided. Thus, it can be used as a reference for similar structure design.
