Prediction of Site Response Spectrum Under Earthquake Vibration Using an Optimized Developed Artificial Neural Network Model

“…Furthermore, the used input parameters in the proposed ANN model can be obtained from routine in-situ or laboratory tests and or exact available formulation. Therefore, to evaluate the feasibility and applicability of ANN in site response prediction and also verify the obtained results from optimized ANN model, a comparison between ANN's outputs using different training algorithms regarding those obtained by numerical time domain, nonlinear analyses [25] were conducted ( Figure 7A and B) and good compatibilities were observed. In both Figure 7A and B, the Y-axis indicates a pseudo spectral acceleration (PSA) while in Figure 7A and B the X-axis refers to the number of total dataset presented to ANN model and the period, respectively.…”

“…1B). The site of the dam is located at 34° 34'20″ to 34°35' north latitude and 48°20' to 48°23'10″ east longitude and has been subjected to earthquake geotechnical analysis [25].…”

“…Therefore, in this paper, the previous databases [25] have been updated using geo-mechanical data and geophysical surveying form field tests and other relevant sources and were categorized into four main subcategories by the authors, as drilled borelog data (e.g. soil layers, soil types, layer thickness, depth to bedrock level), field and laboratory test data (e.g.…”

“…In the introduced model, the importance of the adequate soil behavior using the in-situ and laboratory tests as well as geophysical servying have been considered to simulate earthquake site response spectra. The conducted comparison between the ANN results with a previous study [25] and time domain nonlinear method highlighted an attractive economical engineering based alternative method that can cover and solve some limitations of the conventional methods.…”
