A nonlinear quadrilateral thin flat layered shell element for the modeling of reinforced concrete wall structures
(Springer Netherlands, 2019)
In this article, a simple and accurate quadrilateral thin flat layered shell element formulation for the nonlinear analysis of reinforced concrete (RC) wall systems under static and cycling loads is presented. The 4 node ...
Computational generation of free-form shells in architectural design and civil engineering
(Elsevier Science BvAmsterdamHolanda, 2010)
Formulation of solid-shell finite elements with large displacements considering different transverse shear strains approximations
(Elsevier Science, 2017-08)
This work presents a general formulation and implementation in solid-shell elements of the refined zigzag theory and the trigonometric shear deformation theory in an unified way. The model thus conceived is aimed for use ...
On the analysis of non-homogeneous laminates using the refined zigzag theory
(Elsevier, 2018-11)
This work shows possibilities and limitations of the refined zigzag theory (RZT) that has been used in different structural (beam, plate and shell) finite elements. The refined zigzag theory can deal with composite laminates, ...
Thermal post-buckling behavior of oil storage tanks under a nearby fire
(Elsevier, 2021-02)
This paper reports research on the thermal buckling and post-buckling of vertical steel tanks under heat induced by a nearby burning tank. A two-layer solid flame model is adopted and a heat transfer analysis is carried ...
Análise numérica de estruturas de aço, concreto e mistas em situação de incêndio
(Universidade Federal de Minas GeraisUFMG, 2008-12-09)
This work presents the development and implementation of nonlinear numerical models for the thermal and mechanical analyses of steel, reinforced concrete and composite structures of steel and concrete subjected to fire. ...
Lineamientos de convergencia para el pre – dimensionamiento geométrico en procesos de optimización para el diseño de cascarones de concreto
(Universidad Católica de ColombiaFacultad de IngenieríasBogotáIngeniería Civil, 2022)
Este trabajo de investigación desarrolla recomendaciones para el pre - dimensionamiento de cascarones elipsoidales e hiperbólicos, de concreto reforzado. Para ello, se realizó un análisis de resistencia de múltiples modelos ...
Uncertainty in the inelastic behavior of reinforced concrete walls due to material properties
(2020)
Reinforced concrete (RC) walls are structural elements widely used to resist lateral forces in highly seismic countries. Design codes provide minimum requirements to ensure an adequate performance of shear walls during ...
