A methodology for the probabilistic assessment of behaviour factors

Aníbal Costa; Xavier Romão; Carlos Sousa Oliveira

Given the importance that traditional force-based seismic design still currently exhibits, studies addressing issues related to the definition of the behaviour factor values are considered to be of most interest. A probabilistic methodology is proposed for the calibration of the q-factor relating its value with two fundamental parameters, the displacement ductility capacity measured at a relevant location of th...


Practical aspects of demand and capacity evaluation of RC members in the contex...

Xavier Romão; Raimundo Delgado; Aníbal Costa

The structural safety assessment procedures proposed in Part 3 of Eurocode 8 (EC8-3) for the case of reinforced concrete structures are addressed. The practical evaluation of the member chord rotation demand according to EC8-3 is examined in detail along with several alternative formulations. The need for these formulations is demonstrated by presenting example situations where the EC8-3 proposal is difficult t...


An empirical power comparison of univariate goodness-of-fit tests for normality

Xavier Romão; Raimundo Delgado; Aníbal Costa

A comprehensive power comparison study of existing tests for normality is proposed. Given the importance of this subject and the widespread development of normality tests, comprehensive descriptions and power comparisons of such tests are of considerable interest. Since recent comparison studies do not include several interesting and more recently developed tests, a further comparison of normality tests is cons...


A comparative application of different EC8-3 procedures for the seismic safety ...

Xavier Romão; Raimundo Delgado; João Paulo Miranda Guedes; Aníbal Costa

An application of the EC8-3 procedure for safety assessment is presented herein. Besides testing the applicability of the code procedure, this application aims to assess the consistency of the safety assessment results that are obtained. Based on the application of the EC8-3 procedure, the study assesses if the different methods of analysis that are permitted lead to similar safety results and identifies the fa...


Probabilistic risk assessment of RC building structures with masonry infills

Hugo Rodrigues; Humberto Varum; Aníbal Costa; Xavier Romão; António Arêde; Raimundo Delgado

The study of the seismic vulnerability of existent buildings in urban areas with moderated/high seismic risk is of extreme importance. Earthquake engineering experts, public authorities and general public alike agree on the idea that the assessment of the seismic safety and performance of the built environment is a matter of high priority. The proposed paper aims to carry out a structural fragility study where ...
