Consideración de las Deformaciones por Corte e Inercia Rotacional en el Análisis Dinámico de Pórticos y Tabiques

Pablo J. Sanchez, Victorio E. Sonzogni


The analysis of plane frames with elements of great rigidity for tall buildings requires, in general, to take into account some factors which are usually disregarded when computing
the element matrices.
In this work, a computer code for the static and dynamic analysis of the building response is described. The model is based on Timoshenko beam, including axial, flexural and shear deformations, with a consistent mass matrix including the effects of rotational inertia of the cross section. Rigid portions, as well as hinges, may be included at the element ends.
The element is able to model frame structures uncluding shear walls. The code provides a user friendly interface and may be used for eduactional purposes allowing to include new
capabilities.The influence of factors affecting the response of frames with shear walls in static and dynamic response, as well as in free vibrations, is discussed. Results with finer finite element models are used for comparison purposes.
