Método directo de rigidez aplicado a un pórtico plano de gran altura y verificación con el software calsap

Abstract

The present research work details the process of calculating the direct method of stiffness applied to a flat porch of 12 stories and 3 openings subjected to gravitational loads; Similarly, the programming sequence to perform this calculation with the Computer Assisted Learning of Structural Analysis Procedures CALSAP software is described in order to analyze the results obtained by both methods. The methodology immersed in the matrix analysis of the frame-type structures that allows to find the forces that occur in the elements that compose the frame, based on the dimensioning and physical characteristics of the frame, considering the axially rigid elements, although it is known that this simplification can result in errors in the results. Regarding the bibliographic compilation, the various criteria are evidenced at local, national and international levels, weighing even more the importance of the analysis of the structures in the engineering field. Finally, the process scheme for the calculation by both methods, formulas, equations and processed criteria is presented, as well as the definition of the commands used to obtain results with the aforementioned software; These values are shown in tables for better interpretation.
