This paper presents an experimental investigation in the cyclic load response of hammer-head bridge piers. The paper investigates the response of piers made of precast elements assembled with unbonded prestressing to provide self-centering capabilities under extreme lateral loading. This technique is beneficial in terms of limiting the expected residual deformations after major seismic events. Five one-fifth scale pier prototypes were designed, fabricated and tested under both gravity and lateral cyclic loading in displacement control. The test matrix was designed to investigate the effect of the construction method (monolithic versus precast), level of initial prestressing in the unbonded tendons and the use of energy dissipation rebar to result in fatter hysteresis loops. Experimental results showed that the proposed construction method is indeed capable of enhancing the cyclic load response characteristics in terms of increased ultimate lateral load capacity, reduced residual displacements, delayed damage states and reasonable energy dissipation capacity. The paper serves as a foundation for the next phase of the research program in which a detailed numerical simulation study will be developed to examine various design considerations related to the seismic behavior of such construction method.

A MIXED SMEARED/DISCRETE CRACKING MODELING APPROACH FOR SHEAR CRITICAL REINFORCED CONCRETE BEAMS - 01/0

Dina Muhammad Fathy Ors

01/01/2014

ABSTRACT: This paper presents an analytical study on the modeling of shear critical reinforced concrete beams modeled using the finite element method. The paper investigates two modeling strategies; the first of which is the well established smeared cracking modeling approach. Experimental test results from a wide range of beams tested by other researchers were used for model verification. This paper presents a mixed modeling approach in which the smeared cracking model was used in conjunction with discrete cracking planes to model the concrete continuums in an effort to reach a better correlation with the experimental data. This is achieved by introducing specific plans at the suspected plans of failure for shear critical beams. Analytical results have shown that the proposed modeling approach is capable of better simulation of the observed experimental response in terms of strength and stiffness, as well as capturing the post-peak response of the tested beams.
