Abstract

Bridge piers are critical structural elements designed to withstand seismic loads. Self compacting concrete is a type of concrete that can compact itself without the compacting tools, aiming to overcome difficulties in concrete compaction due to reinforcement congestion. This study utilizes ANSYS software with finite element method. After the processes of data input, meshing, and solving, outputs such as hysteresis curves, stress contours, displacement contours, ductility, stiffness, and energy dissipation were obtained. The capacity of normal concrete bridge piers is compared with the capacity of self compacting concrete with variations in cementitious composite jackets thickness. Specimens E25NC, E10SCC, E25SCC, and E40SCC were able to achieve maximum drift ratio. All specimens exhibited ductility greater than 4 falling into the category of high ductility demand. The stiffness of all specimens decreased along with increased displacement in both push and pull loading directions. Specimen E40SCC maintained the highest initial stiffness and the slowest degradation, indicating greater deformation capacity. Specimen E40SCC consistently demonstrated the highest cumulative energy dissipation at every displacement level. The result of this study prove that cementitious composite jackets thickness has a significant effect on enhancing the structural performance under cyclic loading.
