A frame element model for the analysis of reinforced concrete structures under shear and bending
(2010-10-01)
Article
Restricted access - publisher's policyModeling the response of reinforced concrete structures under combined shear and normal forces involves handling the anisotropic behavior that takes place in the post-cracked and ultimate ranges. Current 2D (plane-stress ... -
A new concrete plastic-damage model with an evolutive dilatancy parameter
(Elsevier, 2019-04-04)
Article
Open AccessTypical plastic-damage models for concrete use a constant dilatancy parameter. On problems sensitive to confinement and shear softening, this parameter needs ad hoc calibration to fit experimental observations. This makes ... -
A new punching shear mechanical model for reinforced concrete slabs with and without punching reinforcement

(2018-07)
Article
Open AccessA punching shear strength mechanical model for RC flat slabs with and without shear reinforcement, based on a beam shear model previously developed by the authors, is presented. The differences in resisting actions between ... -
A variable order framework for 3D nonlinear analysis of reinforced concrete frames under general loading
(Elsevier, 2021-09)
Article
Open AccessA framework for the analysis of three-dimensional reinforced concrete frame structures, capable of reproducing general failure modes, is presented. A force-based model which guarantees the equilibrium between nodal and ... -
Agile analysis of life-cycle damage cost of concrete frame structures under earthquake
(Taylor & Francis Group, 2023)
Part of book or chapter of book
Open AccessSeismic events can produce damage and collapse of constructions, impacting the expected life-cycle cost and out-of-service time. Past seismic events showed that socioeconomic consequences at community scale are dramatic, ... -
