Abstract— A simplified fragility analysis of steel building
frame is presented which can be used for preliminary estimate
of its probability of failure. The risk analysis procedure uses
the format of probabilistic Risk Analysis (PRA) and considers
band limited white noise at the bed rock as the seismic input.
The steel building frame is modeled as a 2D frame and
Pushover analysis is then carried out to obtain its capacity
using SAP 2000. The response of the steel frame is obtained by
response spectrum method of analysis for multi-degree of
freedom system. The PRA includes uncertainties of the
response due to variation of ground motion, material
property, modeling & method of analysis and those of the
capacity due to the variation of ductility factor and damage
concentration effect. The proposed method of analysis is
applied to a 5-storey steel building frame for obtaining its
probability of failure using First Order Second Moment
(FOSM) theory of the Reliability analysis. The fragility curves
for the frame failure were generated for a number of
parametric variations. The parameters include soil conditions,
coefficient of variation of the uncertainty factors, ductility
factor and soil amplification factor . The study shows that all
the parameters considered in the study have considerable
effect on the probability of failure.
