INVESTIGATING VIBRATION IN BRIDGE STRUCTURES CAUSED BY VERTICAL EARTHQUAKE EXCITATION AND MOVING MASS E...
Published 2017-05-01“…It has been observed that as a bridge structure is subjected to moving masses and earthquake loading, the dynamic deflection and stresses can be significantly higher than those observed in the static case. Although only the horizontal component of earthquake excitation is taken into account in the modeling of bridges and parallel beams sustaining the bridge deck loads. there exist several pieces of evidences showing that some of the failure modes are in direct relation to the vertical one. …”

INVESTIGATION OF SHEAR BEHAVIOR AND MODELING OF DEEP BEAMS USING THE FINITE ELEMENT METHOD...
Published 2015-11-01“…Since the ratio of width to height of deep beams is small and concrete acts unsymmetrically against tension and compression, a plain-stress model and nonlinear analysis are used in the study of these beams.In this paper, a finite element program is presented for the nonlinear analysis of two-dimensional and asymmetrical problems. In the case of reinforced concrete structures, the plasticity of concrete in compression, the yielding of reinforcement and the cracking of concrete under tension are accounted for. …”
