Study on Equivalent Damping Ratio of Shenzhen Baoan International Airport T3 Terminal Yuchen Yang1,2,a , Lei Gu2, Zhongyi Zhu1, Kai Qin1, Lin Zhang1 1Beijing Institute of Architectural Design, Beijing,100045 2Harbin Institute of Technology Shenzhen Graduate School, Shenzhen, Guangdong, 518055 ayangyuchen1120@126.com Keywords: non-proportional damping, modal damping, energy method， equivalent damping ratio Abstract.Today, the structures constituted by different materials, increase more and more, especially the lower part is concrete, the upper is steel.
When the single damping ratio 0.02 is used to analyze, the dissipation capacity of the lower concrete is underestimated and the seismic response of concrete is enlarged.This will result in wasting the material and increasing the construction cost.

When studying 3D fatigue crack growth behaviors of materials, to determine the crack opening stress intensity factor ratio is the key issue.
Introduction Even though a lot of investigations have been done on three-dimensional (3D) fatigue crack propagation behaviors of materials, it's far away to predict 3D fatigue crack growth widely with good precise [1, 2, 3, 4, 5].
