In the context of performance\uffe2\uff80\uff90based earthquake engineering, dynamic analysis serves to obtain a probabilistic description of seismic structural vulnerability. This typically involves subjecting a nonlinear numerical computer model to a set of ground\uffe2\uff80\uff90motions that represent a sample of possible realizations of base acceleration at the site of interest. The analysis results are then used to calibrate a stochastic model that describes structural response as a function of shaking intensity. The sample size of the ground\uffe2\uff80\uff90motion record set is nowadays usually governed by computation\uffe2\uff80\uff90demand constraints, yet it directly affects the uncertainty in estimation of seismic response. The present study uses analytical and numerical means to investigate the record sample size, n, required to achieve quantifiable levels of mean relative estimation error on seismic risk metrics. Regression\uffe2\uff80\uff90based cloud analysis in the context of Cornell's reliability method and incremental dynamic analysis using various intensity measures were employed to derive a relation of the form  , where \uffce\uff94 is a parameter that depends on both the dispersion of structural responses and the shape of the hazard curve at the site.

It is a sequence especially interesting to study, from the perspective of seismic actions experienced by structures, because it saw nine M\u00a0\u2265\u00a05.0 earthquakes within a period of 5\u00a0months, rupturing parts of the complex central Apennine mountain range fault system. Consequently, some of the main earthquake engineering issues that arose are the multiple locations where the code-mandated seismic actions were exceeded in more than one of the main events of the sequence and the number of pre- and low-code existing buildings that suffered heavy damage or collapse due to the intensity of individual earthquakes and the cumulative effect of repeated damaging shocks. The present article picks up on these topics and uses probabilistic seismic hazard, as well as the multitude of strong ground motion recordings available from the sequence, to provide a discussion on certain issues, that are all related to the topical subject of seismic actions. These issues are: (1) the unsurprising exceedance of code spectra in the epicentral areas of strong earthquakes; (2) the particular spectral shape and damaging potential of near-source, pulse-like, ground motions, possibly related to rupture directivity; and (3) structural non-linear behaviour in the wake of a sequence that produces repeated strong shaking without the necessary respite for repair and retrofit operations.", "keywords": ["Geophysics", "Seismic Hazard", "Pulse-like ground motion", "Cumulative damage", "0211 other engineering and technologies", "Cumulative damage; Pulse-like ground motion; Seismic hazard; Civil and Structural Engineering; Building and Construction; Geotechnical Engineering and Engineering Geology; Geophysics", "Building and Construction", "02 engineering and technology", "Geotechnical Engineering and Engineering Geology", "Seismic hazard", "Civil and Structural Engineering"]}, "links": [{"href": "http://link.springer.com/content/pdf/10.1007/s10518-017-0295-3.pdf"}, {"href": "https://doi.org/10.1007/s10518-017-0295-3"}, {"rel": "related", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/Bulletin%20of%20Earthquake%20Engineering", "name": "related record", "description": "related record", "type": "application/json"}, {"rel": "self", "type": "application/geo+json", "title": "10.1007/s10518-017-0295-3", "name": "item", "description": "10.1007/s10518-017-0295-3", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/10.1007/s10518-017-0295-3"}, {"rel": "collection", "type": "application/json", "title": "Collection", "name": "collection", "description": "Collection", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main"}], "time": {"date": "2017-12-09T00:00:00Z"}}, {"id": "10.1016/j.enggeo.2016.09.005", "type": "Feature", "geometry": null, "properties": {"license": "Open Access", "updated": "2026-07-27T16:16:22Z", "type": "Journal Article", "created": "2016-09-21", "title": "A general analytical solution for the evolution of cliffs accounting for strength degradation, seismic action, formation of tension cracks and seepage", "description": "Abstract   The evolution of natural slopes over time is ruled by several concurrent physical phenomena, namely the strength of its component geomaterials and their weakening over time due to weathering processes, the occurrence of seismic events, seepage and the formation of tension cracks. The paper presents analytical solutions obtained considering a succession of discrete failure events (landslides) progressively altering the slope morphology over time. The model, derived in the framework of limit analysis assuming plane strain conditions, provides a tool for the assessment of whether manufacts and/or infrastructures located on a slope subject to various natural degradation phenomena will be affected by the occurrence of failures.  Unlike current empirical and semi-empirical models of slope evolution, the analytical solution that is here presented is derived by applying principles of soil and rock mechanics, therefore it is of general validity, so that no ad\u2013hoc calibration against past observations of the evolving slope is needed. This analytical technique only requires knowledge of the (geotechnical) parameters characterising the geomaterials comprising the slope of interest, namely angle of shearing resistance, \u03d5, cohesion, c, tensile strength, unit weight, together with knowledge of the relevant seepage scenarios, strength degradation processes, and seismic events likely to occur.  Results show that that earthquake loading and seepage can substantially decrease slope stability, increase the volume of material sliding away during each landslide event and alter the evolution of the slope over time, while tensile strength exhibits a less strong influence especially as strength degradation progresses.

It is a physically-based model that couples finite strain soil deformation with unsaturated water and air flow, while improving on existing cohesion-based approaches to mechanical root reinforcement and empirical soil water-uptake approaches typically used to deal with rooted slopes. The model is used to show that the dynamics of soil-water pressure and soil deformation depend strongly on the physics of the root-water uptake and the elasto-plastic soil mechanics. Root water uptake can cause suctions and corresponding soil shrinkage sufficiently large to necessitate a finite-strain approach.

Soil and foundation displacements, frame deformed shape, maximum structure deformation parameters (deflection ratios and angular distortions), and associated modification factors are illustrated. Results indicate that unlike equivalent isotropic plates, framed buildings primarily exhibit shear behavior and a semi-flexible response. Building deformed shapes indicate that angular/shear distortions (considering bay slope and local tilt) are more appropriate for quantifying framed building distortions than deflection ratios. A relative stiffness parameter is suggested to relate maximum angular distortions to the greenfield settlement slope. Moreover, the efficiency of the available relative stiffness parameters for the deflection ratio modification factors is confirmed.
