Resumo
In recent decades, the high density of urban centers which are horizontally saturated leads to an increasing necessity of tall buildings. To construct such structures and to guarantee their lateral stability, it is essential to use suitable bracing structures to support lateral loads like wind and seismic actions. Frames, structural walls and shear-walls are examples of these structures. Shear-walls are highlighted due to their significant cross section dimensions inside the building. It is important to determine the lateral load portion which acts in each one of these structural elements, especially because they are working in an associated way. In this context, the main focus of this paper, developed as an undergraduate level research, is the implementation of a didactic computational code based on the Finite Element Method in order to analyze bracing structures (specially, shear-walls), that can be easily used in undergraduated courses, despite of many commercial softwares available, more complex to use considering the students. In order to evaluate the didactic code, simple buildings composed by frames, structural walls and shear-walls submitted to lateral loads distributed along its height are considered and the results are compared with those obtained by a commercial code for structural analysis.
