After the 1995 Kobe earthquake, the structural performance concept of a bridge in Japan considers two levels of seismic excitation which are named as Level 1 and Level 2. However, the Level 2 of ground motion input is a large seismic coefficient demand. Also, the problem of bridge rubber bearing support which commonly is used in Japan lost expected seismic performance due to the deterioration. Some possible causes of the deterioration are the aging, the compression fatigue, or the frequent lateral deformation which triggered by traffic load, wind load, thermal expansion, creeps, and shrinkages phenomena of daily load. While the behavior and the parameters of reinforced concrete (RC) column accompanied with friction device were determined successfully based on the experiment and numerical analysis. This study proposed the structural system of integrated bridge pier with triple RC column connected by friction damper plus gap which is expected to substitute the conventional bridge pier system avoiding the use of rubber bearing. In the investigation of its behavior and seismic performance, numerical analysis was performed with fiber cross-section of non-linear beam-column-based element model on the longitudinal direction of the bridge structure. As the analysis result, the proposed structure had an excellent performance not only under small deformation to allocate frequent lateral deformation but also under seismic load. Furthermore, in the structural simulations, the consideration of different limit state of column location and the various yield strength of reinforcing steel configuration can obtain a better structural cost-performance option.

This paper discusses the optimum seismic performance estimation analysis of the integrated multiple steel pipes bridge pier connected by shear panel damper (SPD). The optimization result to be expected to result in an easier structural design for the practical engineer. In this study, 405 different structural configurations with 35 and more variations of SPD thickness to be analyzed by non-linear static cyclic in order to quantify its energy dissipation. The optimum energy dissipation to be assumed as analogous with best objective seismic perfor- mance in order avoiding time consumption of numerical analysis. Furthermore, the SPD’s thickness related optimum energy dissipation of each structural configuration was successfully predicted by multi-parameter es- timation analysis with the artificial neural network (ANN) method. As the result, the R-value and the average error value of the estimated optimum SPD’s thickness compared with analytical result were 0.988 and 2.38%, respectively. With the estimated empirical equation result, the practical engineer could determine the structural configuration in the optimum seismic performance easily.

In the medium to high seismic zone, prestressed hollow concrete (PHC) pile for structural foundation should be designed with elastic behavior due to low ductility and dissipated energy. However, some Indonesian practical engineer has chosen PHC pile for pile-supported slab viaduct (PSSV) with medium seismic moment-resisting frame concept in a high-risk earthquake zone. Therefore, some nonlinear numerical simulations of PSSV structure in medium to high seismic zone need to be conducted to investigate its seismic performance. In the initial stage, a numerical model for investigating the seismic performance of PHC pile under flexural test was conducted. By implementing an appropriate plastic hinge length of forced beam-column with hinge elements, the flexural behavior of PHC piles to be simulated under both monotonic and cyclic loading. The fiber section was adopted to accommodate non-linear behaviour of material in the PHC pile cross section. As the results, the skeleton curves, the sectional strain distributions, and the hysteresis curves have good agreement results compared with the experimental results. Furthermore, based on the equal damping ratio calculation of the hysteresis curve, the PHC pile only achieve low energy dissipation, though the ductility capacity around 3. Finally, this numerical model approach could be adopted in the non-linear simulation of PSSV structure under seismic load.
