Abstract: A multiplatform simulation of a highway overcrossing bridge is introduced where the embankments, abutments, and pile groups are modeled in a powerful finite-element (FE) package with nonlinear soil material model while the ...

Abstract: In this paper, modeling approaches describing the hysteretic behavior of reinforced-concrete columns subjected to cyclic deformation reversals are investigated. The inelastic flexure and shear response of a reinforced-concrete ...

Abstract: Motivated by the observation that existing damage indices do not take into account the bidirectional and torsional response effects, a new three dimensional damage index is proposed in this paper. The derivation is based ...

Abstract: Nonuniform seismic excitation has been shown through previous analytical studies to adversely affect the response of long-span bridge structures. To further understand this phenomenon, this study investigates the response ...

Abstract: The paper is concerned with loss estimation analysis of flat-slab structures, a reinforced concrete structural form that exhibits behavior and response patterns distinct from conventional moment frames. The fragility ...

Abstract: Due to the nonlinear nature of coordinate transformations, evaluation and calibration of multiaxial loading systems in global Cartesian coordinates are challenging problems. This study proposes a systematic calibration ...

Abstract: The large-scale and catastrophic impacts of Hurricanes Katrina and Rita in 2005 challenged the efficacy of traditional postdisaster temporary housing methods. To address these challenges, the U.S. Congress appropriated ...

Abstract: This paper presents analytical assessment of the effect of vertical earthquake ground motion on RC bridge piers. A bridge structure damaged during the Northridge Earthquake and a Federal Highway concept bridge design are ...

Abstract: Recent analytical studies have shown that reduced column compression and even tension may be experienced by intermediate stories of medium to high-rise reinforced concrete (RC) structures. This is a consequence of high ...

Abstract: The seismic performance of low-rise frames with energy dissipative semirigid connections is evaluated under far and near field artificial ground motion records. Four different connection capacities are employed in the ...
