Abstract: The role of soil–structure interaction (SSI) on the response of seismically isolated bridges is studied. A generic bilinear hysteretic model is utilized to model the isolation system. The behavior of the pier is assumed ...

Abstract: The effects of the element ductility capacity, the flexibility of beams (in terms of the beam span-to-beam depth ratio), the flexibility of columns (in terms of column slenderness ratio), and the level of gravity loads on ...

Abstract: A method based on nonlinear pushover analysis is proposed to quantify the deterministic and probabilistic effects of redundancy on the strength of structural systems. Two indices, the redundancy strength index and the ...

Abstract: The wave propagation in sandwich plate rows with cellular core is analyzed and controlled. Honeycomb core materials of different geometry placed periodically along the structure introduce the proper impedance mismatch ...

Abstract: Rigorous numerical analyses are conducted to study the effects of bidirectional lateral cyclic loading on the hysteretic response of stocky circular thin-walled steel columns. Four unidirectional and eight bidirectional ...

Abstract: A rate-independent cyclic plasticity model for structural steels with a yield plateau is proposed. The model couples nonlinear kinematic hardening with a memory surface in the plastic strain space, to account for the ...

Abstract: Seismic isolation bearings consisting of lubricated sliding bearings and steel dampers exhibit nearly elastoplastic behavior. Accordingly, they can transfer force to bridge substructures which is independent of the level ...

Abstract: New analysis and design procedures have been developed for the performance-based seismic rehabilitation of buildings. Such procedures require accurate estimates to be made of displacements, velocities, and accelerations. ...

Abstract: Energy dissipation systems are being increasingly employed in the United States to provide enhanced seismic protection for new and retrofit building and bridge construction. The hardware utilized includes yielding steel ...
