Study on the Ultimate Limit State of the Curvature for Circular Section Reinforced Concrete Bridge Pier
The ultimate limit state of the curvature for circular section reinforced concrete bridge pier was studied from the uncertainty of the deformation capacity. This article firstly uses the bridge pier with the diameter of 1.0 m as the benchmark pier to study the relations between the ultimate limit state of the dimensionless yield, service and damage control curvature and the axial compression ratio, longitudinal reinforcement ratio and stirrup ratio. Results have shown that axial compression ratio is the main factor influencing the average value at the ultimate limit state of dimensionless yield and service horizontal curvature, while the axial compression ratio and stirrup ratio are main factors influencing the average value at the ultimate limit state of dimensionless damage control horizontal curvature. Then this article built the approximate formula for the calculation of diameter adjustment coefficient for the piers with other sections and diameters corresponding to the ductility at different ultimate limit states by means of regression analysis.
