An Efficient Vertical Seismic Response of a Precast Segmental Bridge Superstructure: A Study

Abstract

This paper investigates numerically the verticalnon-linear dynamic reaction of an easy span segmental bridge superstructure that consists of ABC layoutstandards. The superstructure segments are confused collectively via continuous internal unbonded tendons to make certainthe system’s more desirable self-centering capability. A collection of Incremental Dynamic Analysis (IDA) is carried out with the aid ofscaling a set of vertical historic earthquake floor motions to distinctive intensity ranges. The response of thesegmental superstructure bridge device is evaluated via assessing the variability of feature responseportions and assigning performance limit states.
