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...
Slow instability phenomena can turn into rapid events, showing sudden accelerations and potentially developing in a threat for structures people. In such scenarios, an in-depth understanding of the spatial temporal evolution ground surface displacement field becomes essential preventing potential catastrophes. this work, Multi-Temporal Interferometry SAR (MTInSAR) technique based on COSMO-SkyMed Sentinel-1 acquisitions measurements have been used to study ongoing occurrence, affecting urban...
The seismic site effects are the result of wave amplification processes related to topographic irregularities, sequence soil layers, morphology stratigraphic contacts, dynamic properties soils and input motion features.These local may be responsible for damages structures infrastructures located in different portions urban area, as well they trigger landslide instability processes.In present paper, numerical simulations occurring a real natural slope have been performed through 2D finite...
Abstract The study of processes characterized by impulsive nature (i.e. impacts) can be considered great interest in both physics and engineering disciplines: the geotechnical field, for instance, their effect on interaction between soil structures need to investigated. present work aims at validation, means two-dimensional finite element simulations, a methodology force calibration which uses results obtained from three-dimensional discrete analysis predicting stress base granular bed,...
The assessment of slope susceptibility to seismically-induced displacements receives wide attention in the geotechnical earthquake engineering field, but alteration seismic wave inside and at ground surface due presence a shear band confining quiescent landslide body is rarely investigated. This paper describes preliminary results numerical analysis two step-like FE models, reproducing gentle steep cutting subjected weak earthquakes, thus focusing on amplification processes only. show that...
The design of artificial reefs must be based on the criteria both durability and serviceability. In this respect, seabed subsidence rate related to weight their foundation system should limited. horizontal drift during life small too. study, pertaining behavior made microsilica concrete realized with foundations in bamboo near international airport Hong Kong, 1-year monitoring data calculations reef settlements are shown discussed assess performance adopted mixed deduce nature long-term...
The paper describes the numerical approach adopted to investigate effects of vibrations induced on reinforced concrete (R.C.) buildings by excavation works needed bury an existing railway line crossing urban area in south Italy. construction are carried out dolomitic rocks, characterized a high resistance excavation. Therefore, they may have great impact surrounding environment terms vibrations. study is conducted through uncoupled approach, investigating dynamic response geotechnical system...
The damping characteristics of soils are not accurately predicted in most constitutive models. This paper examines the cyclic performance kinematic hardening models from a posteriori analysis free-field ground response results. Shear stress−strain histories, recorded at local level, used to estimate real variation soil shear modulus and material induced by earthquakes different seismic intensity. results dynamic finite-element simulations specific site indicate that frequency occurrence...
