Seismic response of a reactor vessel subject to horizontal excitation.

Analysis of Pressurized Horizontal Vessels under Seismic Excitation

Codes for design and constructions of pressure-vessel provide a number of loading conditions that have to be considered. Pressures are primary loadings that are applied either internally or externally over the surface of the vessels; applied forces act either at local points or throughout the mass of the vessel. Among applied loads, inertial forces due to ground motion can be relevant when indu...

Damage identification of a flag - shaped hysteresis structure subject to seismic excitation

This research investigates the structural health monitoring of nonlinear structures after a major seismic event. It considers the identification of flag-shaped or pinched hysteretic behaviour in response to structures as a special, perhaps more general, case of a normal hysteretic curve without pinching. The method is based on the overall least squares solution and the asymptotic distribution t...

Dynamic Response of Submerged Vertical Cylinder with Lumped Mass under Seismic Excitation

An analytical approach is presented to assess the response of offshore structures under seismic excitation. This paper evaluates the impacts of different fluid field models and the mass of equipment at the top of offshore structure which is simulated as lumped mass on the responses of offshore structures. To do this, two and three dimensional fluid field models are developed. In three dimension...

A Numerical Evaluation of Seismic Response of Shallow Soil Deposits

This paper employs one-dimensional numerical ground response analysis models to investigate seismic response of shallow cohesive and non-cohesive soil deposits on vertical propagation of horizontal shear waves. Soil response is modelled by traditional equivalent-linear (EL) frequency-domain analysis using DEEPSOIL software and nonlinear (NL) time-domain analysis using OPENSEES software. The ana...
