Desempeño de nudos rígidos en sistema estructural de pórticos a momento de concreto armado en zonas de alto peligro sísmico

Abstract

The main objective of this research work is to carry out the verification through the analysis and design in the beam-column connection of a reinforced concrete structure, through a spectral modal analysis using commercial software, which allows us to carry out an analysis and evaluation of results delivered by the same program, these results will be evaluated using a spreadsheet of a 4-story building, which is located in the city of Santa Rosa, province of Oro, since it is in a high-risk area. seismic, in the spreadsheet you can enter the data to evaluate the type of connection and verification in an automated way of the results of the connection that will be analyzed, verifying if it complies as established by regulations, NEC 15, ACI 318-14 and ACI352RS -02. For the analysis of the beam-column node, reference was made to the design recommendations shown in the ACI 352RS-02 code, in order to carry out the analysis and verification of three different nodes of a mezzanine, with the values shown in the program. since this will allow civil engineers to verify each node, which is very important in moment-resistant frame systems. In this way, the calculations that were made are subject to verification of the connections analyzed according to the technical standard used, in the later at the conclusion the results obtained through the analysis carried out for the evaluation will be presented.
