For the purpose of doing modal and dynamic analysis, tall building structures and multistory building For the purpose of doing modal and dynamic analysis, tall building structures and multistory building structures of vibration isolation foundation and non-isolation models were established respectively. To elaborate the broken stone isolating layer efficacy, top ten order frequencies and modes, sliding displacements of isolation layer, storey drift angles, storey accelerations, top floor relative displacements compared to the ground movement are obtained and contrasted. The result of the present work implies that the broken stone isolation layers are suitable for multistory buildings.

Double-layer barrel vault roofs with double-layer vertical walls are frequently used as a structural system for highly important public buildings; therefore, their seismic design needs special considerations. In this article, the seismic collapse behavior of these structures, used as a lateral load-resisting system, is evaluated by carrying out incremental dynamic analysis. For this purpose, different rise-to-span and height-to-span ratios are considered for the roofs and the walls, respectively. The structures are first designed in accordance with Iranian design codes and then they are modeled in OpenSees. The material and geometric nonlinearities are considered in the analyses, including the buckling response of the compression members. At the next stage, the models are subjected to incremental dynamic analysis and their median collapse capacities are extracted. Collapse margin ratios of various structures are finally derived, following FEMA-P695 methodology, and compared against the established acceptable limits. The obtained results show that collapse of the structures occurs mainly due to the buckling-mode failure of the roof. The collapse performance of the structures with large rise-to-span ratio of roofs and large height-to-span ratio of walls is unacceptable.

Inclusion of ground motion–induced uncertainty in structural response evaluation is an essential component for performance-based earthquake engineering. In current practice, ground motion uncertainty is often represented in performance-based earthquake engineering analysis empirically through the use of one or more ground motion suites. How to quantitatively characterize ground motion–induced structural response uncertainty propagation at different seismic hazard levels has not been thoroughly studied to date. In this study, a procedure to quantify the influence of ground motion uncertainty on elastoplastic single-degree-of-freedom acceleration responses in an incremental dynamic analysis is proposed. By modeling the shape of the incremental dynamic analysis curves, the formula to calculate uncertainty in maximum acceleration responses of linear systems and elastoplastic single-degree-of-freedom systems is constructed. This closed-form calculation provided a quantitative way to establish statistical equivalency for different ground motion suites with regard to acceleration response in these simple systems. This equivalence was validated through a numerical experiment, in which an equivalent ground motion suite for an existing ground motion suite was constructed and shown to yield statistically similar acceleration responses to that of the existing ground motion suite at all intensity levels.
