Multicomponent incremental dynamic analysis considering variable incident angle

Performance-based earthquake engineering (PBEE) is the current trend in designing earthquake-resistant structures. The implementation of the PBEE framework requires the assessment of the structural capacity in multiple earthquake hazard levels. Incremental dynamic analysis (IDA) is considered to be one of the most efficient computational tools for estimating structural capacity; therefore, it is often incorporated into the PBEE framework. Most real world reinforced concrete (RC) buildings can only be represented accurately with three-dimensional (3D) models; hence, a multicomponent incremental dynamic analysis (MIDA) is required in order to carry out an IDA-based PBEE framework. In this work, the implementation of IDA studies in 3D structures is examined, where a two-component seismic excitation is applied, and a new procedure for performing MIDA is proposed. According to the proposed procedure, the MIDA is performed over a sample of record-incident angle pairs that are generated using Latin hypercube sampling (LHS).
