Estimation of effective rigidity in reinforced concrete structures through modal identification tests and sclerometry
It is currently known that the structural elements of a building can crack due to structural failures under service loads, due to frequent low-intensity earthquakes or during the first moments of a severe earthquake, which could result in cracked sections when the action of the earthquake occurs. of...

| description | It is currently known that the structural elements of a building can crack due to structural failures under service loads, due to frequent low-intensity earthquakes or during the first moments of a severe earthquake, which could result in cracked sections when the action of the earthquake occurs. of maximum intensity, for such considerations, the Peruvian norm of seismic analysis does not contemplate cracked sections for seismic analysis. The purpose of this study was to estimate the effective stiffness factors of 4 reinforced concrete buildings. The research has a quantitative approach of non-experimental design, the sample is made up of 4 reinforced concrete buildings in the city of Juliaca, to which sclerometry and modal identification tests were carried out with X16 - 1D sensors to obtain compressive strength. and natural periods of field vibration respectively. Numerical models were obtained with their real concrete resistance considering the existing partitions, to which stiffness reduction factors will be applied using international codes and iterations to approximate their natural periods to the natural periods obtained by modal identification. The results show that there is a difference in natural periods of vibration between the numerical model with real resistances considering the effects of the partitioning and those obtained with modal identification tests in a range of 5 % to 30 %, which shows that the fundamental period field vibration is greater than projected. |
