A polynomial approach for analysis and optimal control of switched nonlinear systems
(UniandesDoctorado en IngenieríaFacultad de Ingeniería, 2009)
"In this dissertation, we investigate how convex semialgebraic geometry and global polynomial optimization can be used to analyze and to design switched nonlinear systems. To deal with stability analysis of switched nonlinear ...
Assessment of the seismic capacity of tall wall buildings using nonlinear finite element modeling.
Two existing RC shear wall buildings of 17 and 26 stories were analyzed using fully nonlinear finite element models, i.e., models that include nonlinear material behavior and geometric nonlinearities. The buildings are ...
Non-linear stability analysis of imperfect thin-walled composite beams
(Pergamon-Elsevier Science Ltd, 2010-03)
The static non-linear behavior of thin-walled composite beams is analyzed considering the effect of initial imperfections. A simple approach is used for determining the influence of imperfection on the buckling, prebuckling ...
A FEM procedure based on positions and unconstrained vectors applied to non-linear dynamic of 3D frames
(ELSEVIER SCIENCE BV, 2011)
This study presents an alternative three-dimensional geometric non-linear frame formulation based on generalized unconstrained vector and positions to solve structures and mechanisms subjected to dynamic loading. The ...
Optimización estructural de un edificio con marcos de concreto reforzado, utilizando el método de capacidad espectral, comparando los resultados de la modelación con plasticidad concentrada y distribuida
(Instituto Tecnológico de Costa Rica, 2020)
A 5 story concrete frame building analysis and design were perform following the static method described in CSCR 2010/14 (CFIA, 2016) and satisfy all requirements for concrete structures in section 8 of CSCR 2010/14 (CFIA, ...
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 ...
Bifurcation theory applied to the analysis of power systems
(Unión Matemática Argentina, 2008-12)
In this paper, several nonlinear phenomena found in the study of power system networks are described in the context of bifurcation theory. Toward this end, a widely studied 3-bus power system model is considered. The ...
