“…In this study, the aforementioned equation was modified to estimate the rate of exceedance of a given performance level for a given seismic environment. As the EDP used for Ultimate Limit State design in most building codes is the interstorey drift, which can be related in a straightforward manner to displacement ductility, μ D , the equation defining the rate of exceedance in terms of the latter may be written as

ν ((), μ_{D}) = \sum_{i = 1}^{N} \int_{M_{0}}^{M_{U}} - \frac{italicdλ ((), M)}{dM} Pr ((), μ > μ_{D} (|,, M, L)) italicdM .

“…Furthermore, some research efforts have been devoted to the explicit definition of design spectra consistent with the performance‐based seismic design philosophy which not only consider the rate of exceedance of seismic intensity but also the probability of exceeding the performance level for which the structure is designed and the inherent uncertainties in the definition of relevant structural properties. Avelar et al proposed a formulation to define uniform fragility spectra for given rates of exceedance of a given Engineering Demand Parameter (EDP), accounting for record‐to‐record variability, for performance‐based earthquake engineering assessment and design via displacement‐based procedures . Also, Loth and Baker developed spectra for structural reliability assessment taking into account the characterization of the ground motion and the joint occurrence frequency of spectral accelerations at several vibration periods.…”

Summary This paper presents a new methodology based on structural performance to determine uniform fragility design spectra, i.e., spectra with the same probability of exceedance of a performance level for a given seismic intensity. The design spectra calculated with this methodology provide directly the lateral strength, in terms of yield‐ pseudo‐accelerations, associated with the rate of exceedance of a specific ductility characterizing the performance level for which the structures will be designed. This procedure involves the assessment of the seismic hazard using a large enough number of seismic records of several magnitudes; these records are simulated with an improved empirical Green function method. The statistics of the performance of a single degree of freedom system are obtained using Monte Carlo simulation considering the seismic demand, the fundamental period, and the strength of the structure as uncertain variables. With these results, the conditional probability that a structure exceeds a specific performance level is obtained. The authors consider that the proposed procedure is a significant improvement to others considered in the literature and a useful research tool for the further development of uniform fragility spectra that can be used for the performance‐based seismic design and retrofit of structures.

“…The inclusion of P-D effects in the displacement based design procedure has been previously investigated [Priestley et al, 2007;Asimakopoulos et al, 2007;Wei et al, 2012;Lopez et al, 2015]. In the present paper a novel way to include P-D effects in the assessment of existing structures is proposed, acting directly on the equivalent viscous damping formulation.…”

During an earthquake, P-D effects could significantly increase the horizontal displacements in a structure; hence, they should be duly accounted for in seismic assessment procedures. Considering the displacement based assessment (DBA) procedure, P-D effects influence the single degree of freedom substitute structure adopted in the procedure both in terms of sheardisplacement relationship and of equivalent viscous damping. The present technical note considers a novel framework to include P-D effects in the DBA procedure. The application of the proposed procedure is illustrated considering the Takeda hysteresis model commonly adopted for reinforced concrete structures.

“…The study of Tsantaki et al (2015) assesses the effect of parameter uncertainty of non-deteriorating P-delta vulnerable single-degree-offreedom systems on the median and dispersion of the collapse capacity. In the last contribution of Lopez et al (2015) an innovative displacement based seismic design procedure for P-Delta sensitive framed structures considering sidesway collapse prevention is presented.…”

The Vienna Congress on Earthquake Engineering and Structural Dynamics, VEESD 2013, took place in August 2013 at the Vienna University of Technology, which is located in the Center of Vienna. This congress aimed at fostering scientific interaction among the vast community of researchers contributing to earthquake engineering, seismology, and structural dynamics in a broad sense. About 400 participants from all over the world delivering about 270 presentations of the latest achievements in these fields made this scientific event a great success.We are proud to present the VEESD 2013 special issue in the Bulletin of Earthquake Engineering. It comprises 13 contributions, which were selected on the basis of the response and feedback of both mini-symposium organizers and participants. The papers of this special issue provide new insight into the state-of-the-art of different fields in earthquake engineering based on experimental, analytical, and numerical studies as well as field observations after earthquakes, as it becomes obvious from the subsequent short summary.The first paper by Weatherill et al. (2015) illustrates the effect of the spatial variability of earthquake ground motions upon the resulting seismic loss of aggregated portfolios of heterogeneous building typologies. Iervolino et al. (2015) present a model on life-cycle assessment considering the effect of damaging aftershocks. Using a probabilistic simulation-based framework Gidaris and Taflanidis (2015) assess the performance and optimal design of fluid viscous dampers through lifecycle criteria. Tasligedik et al. (2015) propose low damage solutions for non-structural drywall partitions capable of reaching high levels of drift without loss of serviceability. Penna (2015) discusses in his contribution several aspects of the seismic response and capacity of stone masonry buildings. By the evaluation of experimental results Petry and Beyer (2015) address the horizontal in-plane
