Seismic Collapse Safety of Reinforced Concrete Buildings. II: Comparative Assessment of Nonductile and Ductile Moment Frames

Rintc Project: Nonlinear Dynamic Analyses of Italian Code-Conforming Reinforced Concrete Buildings for Risk of Collapse Assessment

“…The model has already been used in a similar setting, i.e. for the probabilistic seismic performance assessment of both existing and code-conforming (plane) frame structures [8,12].…”

Performance analysis of damaged buildings applying scenario of related non-linear analyses and damage coefficient

“…U istraživanju [32], iniciranje mehanizma kolapsa zgrada i globalne dinamičke nestabilnosti sistema razmatrano je u funkciji međuspratnog drifta i spektralnih akceleracija primenom inkrementalne dinamičke analize (IDA). Takođe, mnogi rezultati istraživanja na temu mehanizama oštećenja i loma zgrada IDA analizom u kapacitativnom domenu prikazani su u [4], [16], [17], [21].…”

“…Initiation of the collapse mechanism and the system's global dynamic instability were discussed in [32] as a function of inter-storey drifts and spectral acceleration using the IDA analysis. A number of results on damage and fracture mechanisms obtained using IDA analysis in capacitive domain are presented in [4], [16], [17] and [21].…”

Probabilistic Performance Analysis of Existing Buildings under Earthquake Loading

“…The cumulative distribution function (cdf) defined by the statistical distribution of the several IM C realizations represents the fragility curve of the selected limit state. This fragility curve has been, in many cases [Ibarra and Krawinkler, 2005;Jalayer et al, 2007;Zareian and Krawinkler, 2007;Bradley and Dhakal, 2008;Liel et al, 2009;Haselton et al, 2011;Liel et al, 2011] assumed to be well represented by a lognormal cdf which enables it to be written as: where (.) is the normal cdf, and ln η IM C and β IM C are the mean and the standard deviation, respectively, of the distribution.…”
