Abstract

A numerical method is proposed for the seismic response analysis of rectangular and cylindrical tanks accounting for non-linear hydrodynamic effects. The equations of motion are mapped from the physical to the computational domain by means of a change of variable. The numerical [...]

Abstract

Several optimized analysis and modelling strategies are provided in this work in order to address the seismic behaviour of cable-stayed bridges in the elastic range, including the expected error ranges in terms of the tower shape, the main span or the stiffness associated with the [...]

Abstract

The tunnel portal is the most seismically vulnerable section of the tunnel against earthquakes. Due to the combined effects of topographic and geological asymmetric loading, the mechanical characteristics of this type of portal are very complex. In this study, a three-dimensional [...]

Abstract

Base isolation is currently acknowledged as an effective strategy for controlling the seismic response of buildings. However, its implementation is usually limited to buildings considered essential or vital to society, resulting in these systems being rarely regarded as a feasible [...]

Abstract

Structural engineers commonly design superstructures as fixed at the base and transmit the reactions to the infrastructure in order to design the foundation system and estimate the displacement of the soil while disregarding the change in seismic response that this induces. In [...]

Abstract

The paper presents recent results of an ongoing collaborative research project focused on modelling the Kurpsai water dam in Kyrgyzstan. The research team includes scientists and engineers from the USA, Kyrgyzstan, and Uzbekistan. This water dam was selected for modelling because [...]
