This study aims to characterize a series of high-rise reinforced concrete wall buildings located in Antofagasta, Chile, by means of a set of structural indexes commonly used in professional activities in our country and recommended by researchers. To this effect, a total of eight buildings was analyzed, from which, based on their architectural plans and engineering drawings, a series of properties was determined, such as wall and floor area, among others. Additionally, a modal spectral analysis was carried out according to the current Chilean regulations (NCh 433Of.1996Mod.2009 and DS 61) by means of the ETABS software. Next, eleven structural indexes were selected and determined, which are related to stiffness, structural redundancy, and ductility, with the purpose of making a seismic qualification. The obtained values indexes provide information about the expected structural performance of the buildings under a major seismic event. Finally, correlations between the different indexes were established.

AbstractThis case study focuses on the evaluation of the collapse rates of various types of reinforced concrete structures (residential and industrial) as observed from the data collected in Romania after the Mw 7.4 Vrancea earthquake of March 4, 1977. The results of the analyses show that the largest collapse rates were attributed to elevated reinforced concrete silos and water tanks. Moreover, the majority of the collapsed elevated reinforced concrete water tanks were full at the moment of the seismic event. Very small collapse rates were observed for high-rise residential RC structures and for the multi-storey industrial RC structures.
