Abstract: This paper presents a nonlinear static analysis of a reinforced concrete plane frame. It has as main objective is to realize a global stability verification of a plane frame, by using geometric stiffness matrix. In order to obtain first and second order combined effects, equilibrium and kinematic relations were studied in the deformed geometric configuration. These results were obtained by using geometric stiffness matrix and multiplying horizontal forces by Gamma-Z coefficient. Both procedures disclosed very … Show more

“…Plumbridge, Matela and Westwater (2003) presented the formulations for linear and nonlinear analysis by FEM and compared the main differences between them. Bueno and Loriggio (2016) point out that the choice of the most appropriate procedure to be used depends on several factors, such as the magnitude of the displacements and rotations in the structure, the level of normal working forces, the sensitivity of the structure to second order effects, among others.…”
