Study on Admissible Displacement Calculation Method of Double-Column Piers

Abstract—Because of the load capacity design method cannot guarantee the structure to achieve the prospective plastic deformation or ductility requirement, so the displacement of pier should be calculated in the seismic design. This paper focuses on the ductile deformation and allowable displacement of reinforced concrete double-column piers under earthquake action. Based on the nonlinear analysis software ABAQUS, the seismic response and failure state of reinforced concrete double-column piers under transverse earthquake are studied through incremental dynamic analysis (IDA) method. According to the relationship between material constitutive and limit state, the displacements of piers are obtained in three different (the slightly damage limit state, controlled damage limit state and controlled collapse limit state). Besides the pier height and tie beam are also consider in the analysis. The relationship between the displacement angle and the strain of double-column piers under the transverse earthquake action is analyzed and a simplified formula of admissible displacement of pier is proposed. Through verification, this simplified formula is simple and accurate, and can be used in the preliminary design.

Index Terms—Double-column piers, admissible displacement of pier, performance state, concrete damaged plastic model.
