Numerical analysis, design and behavior of rockfill dams with reinforced concrete faces during seismic actions

A Dynamic Analysis of the Interaction of Concrete Face and Rockfill Part in Concrete Faced Rockfill Dams

Introduction Concrete faced rockfill dams have been considered in recent years more than other types of dams due to their low dependency on the bed and the shape of the valley, as well as the simpler construction technology. In this regard, rockfill dams are a suitable substitute for embankment dams because of higher stability of the body and the availability of rock aggregates. On the other h...

Seismic Behavior of Steel Reinforced Concrete Beam-Columns and Frames

The ability to perform accurate nonlinear simulations is a key component in the assessment of the behavior of seismic force resisting systems. A three-dimensional distributed plasticity formulation for composite beam-columns suitable for nonlinear static and dynamic analyses of composite seismic force resisting systems has been developed. New uniaxial constitutive relations are developed for th...

Inverse Parametric Analysis of Seismic Permanent Deformation for Earth-Rockfill Dams Using Artificial Neural Networks

This paper investigates the potential application of artificial neural networks in permanent deformation parameter identification for rockfill dams. Two kinds of neural network models, multilayer feedforward network BP and radial basis function RBF networks, are adopted to identify the parameters of seismic permanent deformation for Zipingpu Dam in China. The dynamic analysis is carried out by ...

Yield curvature for seismic design of circular reinforced concrete columns

A Numerical Approach for the Seismic Analysis of Reinforced Concrete Structures Environmentally Damaged and Cable-strengthened

The paper deals with a numerical analusis for the seismic response of reinforced concrete structures containing cable elements. The cable behaviour is considered as nonconvex and nonmonotone one and is described by generalized subdifferential relations including loosening, elastoplastic fracturing etc. effects. The problem is treated incrementally by double discretization: in space by finite el...
