Análisis comparativo utilizando el método tiempo – historia con el espectrograma del sismo el centro y la Norma Ecuatoriana de la Construcción NEC 2015

Abstract

In the initial part of the research project has released the theoretical part on the basic concepts such as earthquakes, ways of measuring earthquakes, types of structural analysis and details on the data spectrogram, in order to understand the purpose of this work. So this paper poses the link information comparing the Design Based on Forces (DBF) of the Ecuadorian Standard Construction (NEC) 2015 and Dynamic Analysis Linear Time-History (ADLT-H), which is of great useful in research and application of Civil Engineering. Specifically it made the DBF of a 9-storey building in the city of Ambato, previously performed the manual calculated the pre-dimensioning of all structural elements based on ACI 318-14 static charges. For live loads, vibration period, were based design spectrum to the current standard NEC 2015. The same structure stabilized by the NEC DBF 2015, an ADLT-H is performed including the earthquake spectrogram "The Center" spectrogram data is corrected provided the Teaching Ing. Mg Jorge Cevallos C. W. specialized area Structures. By comparative analysis of DBF and ADLT-H, they will be collated numerically and graphically seismic coefficient, periods of vibration of the structure, horizontal displacements, derived from P-floors and Delta effects. This type of research is of great importance and provides insight into the dynamic behavior of the structures and designing earthquake resistant structures with real earthquakes.
