Análise por computadores de pórticos planos com elementos de eixo curvo e seção variável
The scope of this paper is to analyse plane frames with curved and straight members, with uniform or non-uniform cross section. The matricial analysis technique, together with computer methods, are used to solve the problem. A computer program is organized in such a way to allow introduction of hinges in the different structural members. The first part deals with the theoretical analysis of the structure. All the steps are organized conveniently in order to prepare the elaboration of the computer program. ln the second part we describe the flow chart and discuss all the intermediate steps. The loading conditions and the flexibility of the solution, regarding the geometrical characteristics of the structural members, are analysed. Finally, the method is used to solve some examples and the results are presented.
