The objective of this work is to study the influence of various sources of uncertainties on the seismic response of structural systems. For this purpose, four test examples are considered, in particular two steel and two steel–concrete composite buildings. In order to study the impact of uncertainty on this type of structure, life-cycle cost analysis is performed for each structure, which is a measure of the damage cost due to future earthquakes that will occur during the design life of a structure. The calculation of the life-cycle cost of structural systems requires the calculation of the structural capacity in multiple earthquake hazard levels. Multicomponent incremental dynamic analysis (MIDA) is considered as one of the most efficient procedures for estimating the seismic capacity of 3D structural systems; therefore, in this work, MIDA is incorporated into the seismic loss estimation procedure. In order to take into account uncertainty on the mass, the material properties, the damping and the record-incident angle, the Latin hypercube sampling method is integrated into the MIDA framework.
