PREdiction of NOn-LINear soil behavior (PRENOLIN) is an international benchmark aiming to test multiple numerical simulation codes that are capable predicting nonlinear seismic site response with various constitutive models.One the objectives this project assessment uncertainties associated 1D effects.A first verification phase (i.e., comparison between on simple idealistic cases) will be followed by a validation phase, comparing predictions such estimations actual strongmotion recordings...
This article presents the main results of validation phase PRENOLIN project.PRENOLIN is an international benchmark on 1D nonlinear (NL) site-response analysis.This project involved 19 teams with 23 different codes tested.It was divided into two phases; first verifying numerical solution these idealized soil profiles using simple signals and real seismic records.The second described in this referred to code for analysis instrumented sites.This performed sites (KSRH10 Sendai) Japanese...
The Central Italy earthquake sequence nominally began on 24 August 2016 with a M6.1 event normal fault that produced devastating effects in the town of Amatrice and several nearby villages hamlets. A major international response was undertaken to record this disaster, including surface faulting, ground motions, landslides, damage patterns structures. This work targeted development high-value case histories useful future research. Subsequent events October exacerbated previously affected...
The development of a soil shear rupture during an earthquake can occur along unstable slopes and at the foundation level, for sliding failure mechanisms. This singularity in seismic wave propagation is not implemented common codes one-dimensional response analysis, usually including linear equivalent models. Instead, code developed this study was conceived, addressed optimised to reliably model both ‘transient’ (‘stick’ mode) permanent deformation mechanisms accounting coupled effects...
The Central Italy earthquake sequence has, to date, generated three mainshocks: M6.1 24 August, M5.9 26 October, and M6.5 30 October 2016. These events, along with aftershocks, were well recorded by Italian networks, are among the normal fault earthquakes highest number of recordings globally. We process records for six events using procedures developed during latest Next Generation Attenuation (NGA-West2) project, coordinated Pacific Earthquake Engineering Research Center (PEER). Many...
The importance of predictions earthquake-induced pore water pressure has been widely recognized for reliable evaluations strong-motion response saturated soil. build-up excess pressure, in fact, causes reduction soil stiffness and strength, some cases leading to liquefaction. Simplified predictive models the literature are empirically based on results cyclic laboratory tests carried out strain- or stress-controlled conditions. Most such empirical require, preliminarily, that irregular...
A good‐working balance between simplicity and reliability in assessing seismic slope stability is represented by displacement‐based methods, which the effects of deformability ductility can be either decoupled or coupled dynamic analyses. In this paper, a 1D lumped mass “stick‐slip” model developed, accounting for soil heterogeneity non‐linear behaviour, with base sliding mechanism at potential rupture surface. The results preliminary calibration show good agreement frequency‐domain site...
