Concrete Bridge Pier Performance under Earthquake Loading
Rozaina Ismail and Mohd Ritzman Abdul Karim
 
Abstract: This study discussed the performance of concrete bridge pier due to earthquake loading by using LUSAS. This research included analysis of the seismic behaviour of concrete bridge deck. An analysis was conducted by using real earthquake records. The variation of normal stresses under seismic loading on the bridge deck in vertical direction is high compare with stresses in horizontal direction seems to be low. Overall the bridge deck can safely withstand by a variation forces and it is achieved based on the determined stress and displacement from the seismic load. This study has demonstrated a nonlinear analysis capable of capturing an extreme loading under seismic excitation which can be very effective in assessment of the damage and stability condition of the bridge deck. In the case of Kepong Bridge, Kuala Lumpur such analysis proved that the bridge suffers damage but remain stable. The result of this analysis shows that the bridge pier suffers some damages but it still remains stable. The result was captured using LUSAS 14.3 Software which means that the software able to analyze a seismic response. The research also provides evidence on a nonlinear analysis that able to capture an extreme loading under seismic excitation which is very reliable in assessing the damage and the stability condition of the bridge pier. Based on thedamages during the analysis under time history, it can be said that Kepong Bridge, Kuala Lumpur is still save under earthquake load which is the maximum ground acceleration of the earthquake is 0.012 g.
