Finite element modeling of plastic hinges based on ductility demand-capacity method using nonlinear material for dynamic analysis
Abstract
The article discusses modeling plastic hinges in reinforced concrete interme-diate supports using finite elements methods. The ductility demand-capacitymethod was used to determine the geometrical parameters of cross-section plas-ticization zones, their ability to move and rotate, as well as their ductility. Dueto the varied geometry and stiffness of the supports and their nonlinear behav-ior under dynamic load, this method was concluded to be imperfect. Therefore,an improved algorithm was proposed by determining the main parameters ofplastic hinges depending on the degree of concrete degradation according toLubliner’s assumptions. The new algorithm has been implemented in the formof mathematical equations. It was subsequently used, at the structure designstage, to perform numerical calculations based on the finite element method.
