Abstract

This paper focuses on the collapse analysis of a planar RC frame. This research is based on an experimental study presented in the literature. The analyses are conducted using a dedicated software based on the Applied Element Method. This numerical method is able to model accurately all the structural behaviour stages leading up to the collapse itself. A very good match between the experimental and numerical results is observed. The numerical investigation highlights several behaviour stages for the model RC frame. Moreover, the contribution of the RC slab and the impact of the concrete strength on the overall collapse mechanism is discussed and evaluated through numerical investigation.

Abstract

The paper presents a series of the results obtained from an extensive questionnaire survey conducted in Bucharest in 2016. The investigated topics are related to earthquake awareness and preparedness of the population currently living in the capital city of Romania, safety concerns and post-earthquake behaviour. Results are interpreted based on several criteria which characterize the target population such as age, education, income, children, as well as the type and year of construction of the building they inhabit. The questionnaire was completed by 1000 respondents and the main findings show that people are generally neither well informed nor prepared for a future major seismic event affecting Bucharest. However, the level of involvement in postearthquake situations is positive, the majority of respondents agreeing to offer humanitarian help in various forms as well as temporary shelter to people, especially relatives or friends.
