Displacement-based seismic performance of RC bridge pier

چکیده
Abstract To correctly manage the road infrastructure before and after an earthquake, it is necessary to estimate even predict seismic performance of bridge. The quantification bridge's response was present in terms displacement also based on previous research reinforced concrete bridge pier models. did define from a force lateral-displacement diagram corresponding capacity curve, calculated through non-linear static pushover analysis model for each limit state, intact state collapse. Thus, six defined displacements correspond cracking displacement, yielding spalling crushing buckling fracturing displacement. states state. Also, parametric carry out evaluate influence, relative importance, trend input parameters model. Eleven analyze as compressive strength, yield stress reinforcing steel, cover thickness, aspect ratio, configuration transverse reinforcement, spacing transversal diameter longitudinal reinforcement axial load coefficient subgrade reaction.

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...
متن کاملSeismic Retrofit of Bridge Steel Truss Pier Anchorage Connections
In assessments of the seismic adequacy of existing steel bridges, the steel-to-concrete anchorage connections typically found at the base of steel truss piers can be potentially vulnerable, having little to no ductility and inadequate strength to resist seismic demands. Many other non-ductile failure locations may also exist along the seismic load path. Failure would result in unacceptable perf...
متن کاملSeismic Performance of RC Frames Irregular in Elevation Designed Based on Iranian Seismic Code
Setback in elevation of a structure is a special irregularity with considerable effect on its seismic performance. This paper addresses multistory Reinforced Concrete (RC) frame buildings, regular and irregular in elevation. Several multistory Reinforced Concrete Moment Resisting Frames (RCMRFs) with different types of setbacks, as well as the regular frames in elevation, are designed according...
متن کاملSeismic Performance of Square RC Bridge Columns under Combined Loading including Torsion with Low Shear
During earthquake excitations, reinforced concrete bridge columns can be subjected to a combination of axial load, shear force, flexural moments, and torsional moments. The torsional moment can be much more significant in columns of bridges that are skewed, curved, have unequal spans, or unequal column heights. Combined loading including torsion can result in complex flexural and shear failure ...
متن کاملProbabilistic Evaluation of Seismic Performance of RC Bridges in Iran
Many existing bridges were designed without adequate consideration of seismic risk. The full or partial collapse of even one major bridge in a city or community would have destroying results. There has been focuses on developing fragility-based seismic vulnerability of existing usual bridges in Iran or support decision making on seismic upgrade. This article focuses on developing performance b...
