heal.abstract	The performance of a 4-story reinforced concrete moment resisting frame building, a 12-story RC coupled wall building and a 7-story RC shear wall building is evaluated. The moment resisting frame building is designed for USA using three different approaches, namely by using the Yield Point Spectrum as a basis for the design (code compatible design) and two other more advanced methods that rely on the Yield Frequency Spectrum and can account for hazard and uncertainty. These methods offer a direct performance-based seismic design and provide a fast algorithm to achieve compliance of a structure to user-specified performance targets. For the performance assessment of the building two different models are examined: a distributed plasticity model to accurately capture the structural response at low intensity levels and a lumped plasticity model to capture the structural response at high intensity levels. For assessment only the lumped plasticity model is employed, after having been calibrated to match the pre-yield behaviour of the distributed plasticity model. The 12 story coupled wall building and the 7 story shear wall building are designed for Europe using the Yield Point Spectrum and the Yield Frequency spectrum as a basis for the design, respectively. A two dimensional model of each structure is used for the performance assessment, that employs distributed plasticity displacement-based elements. Non-linear static analyses are performed for the qualitative assessment of all buildings, while nonlinear response history analysis is employed for quantifying the performance. Specifically single and double stripe analyses are employed in tandem with a practical Factored Capacity versus Factored Demand checking format. For verification, the mean annual frequency of exceeding each performance objective of interest is also estimated, based on incremental dynamic analysis results. Results indicate that the Yield Point Spectrum offers a fair assessment when performance objectives with probability of exceedance 10% in 50 years (code compatible) are examined. The results for performance objectives with different probability of exceedance were not satisfactory. The Yield Frequency Spectra led to a far more accurate design, fulfilling the stated performance objectives. Together with the simple checking format, the two may constitute a viable approach for direct performance based design that can be easily employed in practice.	en
