The linear and nonlinear responses of a selected arch dam subjected to earthquake ground motion are presented in this study. The hydrodynamic e ects on the dynamic response of arch dams are investigat...
Non-linear analysis of externally prestressed concrete beams
Cable strain external cable unbonded deviator displacement
2009/2/20
In an external prestressing system, there is no strain compatibility between the cable and the concrete at every cross-section, the increment of cable strain must be evaluated by taking into account t...

Allowable stress design Non-linear analysis Semi-rigid connections Steel design Unbraced frame
2009/2/19
This article presents an analysis and design method for steel frames with semi-rigid connections and semirigid column bases. The analysis takes into account both the non-linear behaviour of beam-to-co...
Non-linear analysis of dowelled timber connections: a new approach for embedding modelling
Non linear analysis Dowelled timber connection Finite-element method Contact
2009/2/18
finite element modelling is developed to analyse the behaviour of timber connections taking into account the plastic behaviour of the timber beneath the fasteners. The local non linearities control t...
NON-LINEAR STATIC MODELING OF DIP-SLIP FAULTS FOR STUDYING GROUND SURFACE DEFORMATION USING APPLIED ELEMENT METHOD
Applied Element Method AEM active fault dip-slip fault
