For a 30m deep 1-D soil site of about 0.5s period with a soft soil layer at the surface overlying a stiff layer above bedrock, the short-period amplification characterist [...]

The accuracy of six existing R-factor models for estimating inelastic response spectra is evaluated by using a suite of forward-directivity records and single-degree-of-f [...]

Soil-structure interaction can affect seismic responses of structures due to foundation flexibility and energy dissipation. The significance of these effects depends on t [...]

Bridges, as the most critical component in transportation system, have suffered various levels of damages due to strong shaking or liquefaction-induced spreading in past [...]

Seismic isolation can be used to improve the seismic response and reduce damages of bridges. This paper aims to use the performance-based evaluation approach to investiga [...]

The seismic evaluation of RC bridges requires a column model capturing the nonlinear behavior and the induced damage due to the combined effects of axial-shear-flexural i [...]

Estimation of seismic earth pressures constitutes an important subject of research in civil engineering. Previous studies showed strong dependence of earth pressure coeff [...]

Static pushover analyses are utilized to evaluate the vulnerability of typical older-vintage California bridges with continuous superstructures and monolithic abutments t [...]
