All recorded data (acceleration and displacement time histories) and the videos of the tests can be requested online on the EUCENTRE repository at the URL www.eucentre.it/nam-project referring to EUC-BUILD-2.
We can see that the correlation coefficient between the two displacement time series and wind series are − 0.72 and − 0.714, which means the movements of the middle span have a high correlation with the wind.
The testing data including overpressure time histories of vented gas explosions, displacement time histories, and damage characteristics of AAC masonry walls in each test were recorded and analysed.
The results indicate the adequacy of both types of element formulations in predicting the displacement time history and the maximum displacement with reasonable accuracy.
The structural responses of frames are studied in terms of capacity curve, drift ratio, global damage index, base shear, storey displacements, roof displacement time history and plastification.
Here, the cross-correlation was considered between the displacement time series and a 3-year ramp function consisting of a linear slope over a 1-year period that connects flat slopes in the previous and following years (Fig. 5).
The characteristics of earthquakes in the time frequency domain are studied on spectrograms; furthermore, linkages between the spectrogram, displacement time history, and the Fourier Transform are identified to locate intervals during which DR is expected to occur.
The finite element software SAP2000 was used to analyze the failure of the specimen, the displacement time history curve and sequence of the plastic hinges.
We fitted an exponential-decay function for the observed transient in a form of u(t) = A(1 - exp(1 - t/t0)), where u, t, t0, and A is displacement, time, decay-time constant, and amplitude of transient displacement, respectively.
The testing data including overpressure time histories of vented gas explosions, displacement time histories, damage characteristics and fragment distribution of each wall specimen were recorded and analyzed.
We computed uniform hazard spectra (Figs. 11, 14, 17) and also best-fitting scenario earthquake ground motion acceleration, velocity, and displacement time histories for the three locations summarized in Table 3.
