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 presents a detailed seismic performance assessment of a complex bridge designed as a reference application of modern codes for the Federal Highway Administration. The assessment utilizes state-of-the-art assessment ...

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: For the Lehigh-Purdue concrete plasticity model, there seems to be certain limitations on the choice of material properties to ensure the convexity of the limiting surfaces describing the model. A set of inequalities is ...

Abstract: In this paper, a new general procedure is presented for modeling the effects of large displacements on the response of space frames subjected to conservative loading. An incremental definition of rotations is adopted based ...

Abstract: This paper presents the experimental results from a large research project dealing with the seismic behavior of semirigid steel frames. The investigation focuses on the performance of steel frames with semirigid connections ...
