Análisis comparativo de la respuesta no lineal en marcos planos especiales a momento de hormigón armado y acero elaborados en OpenSees versus SAP2000

Abstract

The following paper details the design and procedure to develop nonlinear analysis in SMF (special moment frame), to carry on these analyzes, is required the use of the programs SAP2000 and Opensees, in which ones the results were obtained, the respective comparison was made. The first chapters describe the theoretical foundations used to implement the Nonlinear Static Analysis, its implications, and requirements, after that, using the same parameters previously mentioned will be used to implement the Nonlinear Dynamic Analysis. In next chapters the design of the elements required for the realization of this project will be presented, as well as the layout of the structure is described, the models involved in the analysis, the materials used for the design of these, and all the required and needed information involved in the investigation. Because this research involves more than one fundamental design material, different reviews are carried out, that are essential to ensure that the modeling elements are adequate. In the modeling section, a very appropriate instructive, will be defined to carry on with the Static and Dynamic analysis of a Nonlinear type in plane frames, an in-depth analysis of all data, settings, and design codes needed to generate the models in both Software’s, SAP2000 and Opensees. After that, the results obtained from the modeling of the plane frames will be presented, apart from getting satisfactory comparisons, regarding the periods of the structures, with adequate differentiation percentages, the comparative of acceleration and displacement graphs were also obtained, therefore the use of other models and design methodologies, can be optimal and effective in the development and within Civil Engineering.
