Seismic performance of fabricated reinforced concrete bridge piers based on durable grouting material

نویسندگان

چکیده

Abstract To meet the high durable requirements of assembled bridge piers in marine environment, a new grout is used sleeve to improve corrosion resistance pier bottom. The seismic performance adopting this studied. Firstly, dynamic analysis model reinforced concrete with established using finite element software ABAQUS. Moreover, damage modes, hysteresis curves, and energy consumption for low reversal cyclic loading are investigated. results indicate that failure mode precast at joints members, local does not affect integral pier.

Impact of Long-term Material Degradation on Seismic Performance of a Reinforced Concrete Bridge

A Performance-Based Earthquake Engineering (PBEE) assessment methodology is being used to study the impact of long-term material degradation on seismic performance of reinforced concrete bridges. The methodology, currently under development by the Pacific Earthquake Engineering Research Center, is being applied to an overpass with typical California highway details, and preliminary results are ...

Seismic Design of Concrete-Filled Circular Steel Bridge Piers

The adequacy of the existing design provisions for concrete-filled steel pipes subjected to axial forces and flexure is reviewed by comparing the strengths predicted by the CAN/CSA-S16.1-M94, AISC LRFD 1994, and the Eurocode 4 1994 codes and standards against experimental data from a number of investigators. New proposed design equations are then developed, in a format compatible with North Ame...

Reinforced Concrete Bridge Piers Subjected to Reversed Cyclic Loading

Sixteen large-scale reinforced concrete specimens without web reinforcements were tested to study the behavior of typical bridge piers subjected to deflection reversals that were large enough to cause extensive yielding of the longitudinal reinforcement. The different parameters considered included shear spanto-depth ratio, percentage of longitudinal reinforcement, frequency of the applied load...

Damage-Based Seismic Performance Evaluation of Reinforced Concrete Frames

A damage-based approach for the performance-based seismic assessment of reinforced concrete frame structures is proposed. A new methodology for structural damage assessment is developed that utilizes response information at the material level in each section fiber. The concept of the damage evolution is analyzed at the section level and the computed damage is calibrated with observed experiment...

PERFORMANCE-BASED SEISMIC DESIGN OPTIMIZATION FOR MULI-COLUMN RC BRIDGE PIERS, CONSIDERING QUASI-ISOLATION

In this paper an optimization framework is presented for automated performance-based seismic design of bridges consisting of multi-column RC pier substructures. The beneficial effects of fusing components on seismic performance of the quasi-isolated system is duly addressed in analysis and design. The proposed method is based on a two-step structural analysis consisting of a linear modal dynami...
