Probabilistic evaluation of design live loads for Brazilian light-duty vehicle parking garages

Abstract Design loads for parking garages should be reviewed every few years due to changes in fleet characteristics and the impact of design on carbon emissions by built environment. Specifically Brazil, authors are unaware existing studies justify values corresponding exceedance probabilities stated NBR 6120:2019 - Loads Structures. In this paper, a simplified probabilistic model live is presented. A set updated statistics characterizing gross curb weight circulation was obtained based technical specifications sales reports between 2003 2022. These load employed derive equivalent uniform 30% probability being exceeded 50 years, according definition 8681:2003. The results provide support significant reduction current light-duty vehicle garages, from 3.0 kN/m2 at least 2.5 kN/m2. Such has new building construction costs would not compromise structural safety Brazil.
