The impact of the earthquake incident angle on the seismic loss estimation

Correlation between ground motion intensity measures and seismic damage of 3D R/C buildings

“…[17][18][19], as well as of the inelastic response and damage level, e.g. [20][21][22][23][24]. In a preliminary study, Fontara et al [25] examined the interrelationship between commonly used seismic intensity measures and the Park and Ang overall structural damage index of an asymmetric 3D single-storey R/C building taking into account several incident angles.…”

Ground motion records for seismic performance assessment: To rotate or not to rotate?

“…Reyes and Kalkan proposed rotating the records to the FN/FP directions as well as to the maximum direction and using the overall maximum as design value. Lagaros implemented IDA on plan symmetric and asymmetric 3D mid‐rise RC buildings for various angles of incidence and proposed the use of a moderate number of records and several incident angles for efficient and reliable assessment of performance. Similarly, Fragiadakis et al highlighted that different records, from different earthquake events or even different recording stations, produce considerably different demands, so a relatively large set of records is essential in order to get reliable response estimates.…”

Generation of artificial accelerograms for efficient life-cycle cost analysis of structures

“…In LCCA a multiple hazard level approach should be considered; the two most appropriate ones are the multi-stripe dynamic analysis and the incremental dynamic analysis [13], to be consistent with terminology in related literature the abbreviation IDA is used for both methods. The main objective of IDA [14] is to correlate the seismic intensity level and the corresponding maximum response of the structural system. The intensity level and the structural response are described through an intensity measure (IM) and an engineering demand parameter (EDP), respectively.…”
