Abstract

Abstract

The seismic performance of the traditional reinforced concrete pier is insufficient under strong earthquakes, but the concrete filled steel tube (CFST) pier has better seismic performance. CFST pier has broad application prospects in highway, expressway, urban expressway and high-speed railway, and has been gradually popularized in bridge structure in recent years. In order to improve the seismic toughness of bridge piers, the ultimate seismic capacity of square section reinforced concrete piers, partially filled CFST piers, CFST piers and stirrup-confined CFST piers are compared and studied. Seismic elastoplastic and plastic large deformation time history analysis of full-size finite element models of square section reinforced concrete pier, partially filled CFST pier, CFST pier and stirrup-confined CFST pier were carried out, and the seismic limit performance and application range of different types of pier were discussed. In the analysis, the finite element software ABAQUS is used to establish a refined finite element model of solid shell. In the model, a parametric deterministic concrete triaxial plastic-damage model is adopted for the concrete stress-strain relationship, and crack insertion technology is introduced. The combined hardening-ductile damage model of steel stress-strain relationship was adopted, and the finite element model was verified by the existing experimental results of the seismic performance of reinforced concrete pier, partially filled CFST pier, CFST pier and and stirrup-confined CFST pier under unidirectional pseudo-static, unidirectional pseudo-dynamic, bidirectional pseudo-dynamic, and shake table loading test. Finally, three evaluation indexes: displacement response, cumulative energy dissipation and stiffness damage, are used to evaluate the seismic toughness of various piers under different ground motion intensity at the same cost. The analysis results show that: 1) the elastic-plastic and large deformation seismic calculation methods of the refined solid-shell FE model of CFST pier can reasonably reflect the “pinch” effect of hysteretic curve under cyclic load, the degradation of bearing capacity during large plastic deformation and the displacement response under dynamic load. 2) When the bridge fortification requirement is 6-7 degrees, it is recommended to choose reinforced concrete pier; when the bridge fortification requirement is 8 degrees, it is recommended to choose CFST pier. When the bridge fortification requirement is 9 degrees or above, it is recommended to choose the stirrup-confined CFST pier.
