英文摘要: Abstract(#br)This paper presents a numerical evaluation of the effectiveness of shock absorber devices installed between roller bearing and stopper in reducing viaduct damage. The effectiveness of thickness and types of shock absorber devices on mitigating viaduct damage is investigated accordingly. The thickness of shock absorber devices is from 0cm to 8cm, with increment of 2cm. The viaduct seismic performance is evaluated for five cases based on the thickness of shock absorber devices. In addition, three cases are studied based on the different design parameters of shock absorber devices. The three cases include viaducts with strain hardening, elastic, and strain softening shock absorber devices. Moreover, the pounding forces...
