Evaluating Failure Patterns and Bursting Loads in Concrete Segmental Bridge Piers: A Comprehensive Study

This study presented an experimental and numerical investigation focused on pier segments of segmental bridge types.The pier segments were constructed to represent Lak Si Overpass Highway Route No. 304, Thailand.The experimental program included five pier segments with similar reinforcement details but varying concrete strengths.The numerical work validated the finite element model (FEM) using experimental results and conducted a parametric study to assess the impact of steel reinforcement variation and concrete compressive strength on the bursting capacity of pier segments.Key findings included a consistent failure pattern characterized by a prominent vertical crack and concrete crushing at the bottom, particularly in specimens
