Abstract (EN):
The paper discusses the overall effect of the angle of seismic incidence during the
seismic safety assessment of reinforced concrete buildings employing state-of-the-art
methods of analysis, and provides proposals on how to account for this effect.
Particularly, the Performance Based Earthquake Engineering (PBEE) methodology
developed by the Pacific Earthquake Engineering Research (PEER) Centre is applied to
six reinforced concrete buildings and the effect of the angle of seismic incidence is
evaluated in all relevant stages of the procedure. The PEER-PBEE methodology
provides a general framework for the probabilistic assessment of the seismic
performance of individual buildings, it comprises four stages of analyses, and yields
results that are of interest both for practitioner engineers and stakeholders. The angle of
seismic incidence is involved in the second stage of the framework, which includes the
structural analysis of the building, and primarily affects the resulting engineering demand
parameters. Subsequently, the propagation of the effect of the angle of seismic incidence
is also examined in the following two stages of the framework, which involve the damage
and the loss analysis of the building. Different metrics of building performance are
analysed in each stage of the framework, including two engineering demand parameters
(in the structural analysis stage), the probability of collapse (in the damage analysis
stage) and the expected annual loss of the building (in the loss analysis stage).
Proposals to account for the angle of seismic incidence are provided based both on
results obtained for each individual stage of the framework, as well as on the overall
assessment procedure.
