Observations after strong earthquakes show that out-of-plane failure of unreinforced masonry elements probably constitutes the most serious life-safety hazard for this type construction. Existing buildings tend to be more vulnerable than new buildings, not only because they have been designed little or no seismic loading requirements, but also connections among load-bearing walls and with horizontal structures are always adequate. Consequently, several types mechanisms can activated due...
SUMMARY The evaluation of the out‐of‐plane behaviour unreinforced walls is one most debated topics in seismic assessment existing masonry buildings. discontinuous nature and its interaction with remainder building make dynamic modelling response troublesome. In this paper, results a shaking table laboratory campaign on tuff masonry, natural scale, U‐shaped assemblage (façade adjacent to transverse walls) are presented. tests, excited by scaled accelerograms, replicate external buildings,...
This paper documents and analyzes the seismic behavior of unreinforced masonry (URM) buildings that were damaged by 2015 Gorkha earthquake in Nepal, reports on performance palaces, giving an overview failures suffered significant examples these monumental buildings. Field reconnaissance was completed through both rapid, in-situ visual assessment state-of-the-art procedures utilizing light detection ranging (lidar) virtual reality (VR) technologies. Both assessments compared for 20 structures...
Abstract City centres of Europe are often composed unreinforced masonry structural aggregates, whose seismic response is challenging to predict. To advance the state art on these Adjacent Interacting Masonry Structures (AIMS) subproject from Horizon 2020 project Seismology and Earthquake Engineering Research Infrastructure Alliance for (SERA) provides shake-table test data a two-unit, double-leaf stone aggregate subjected two horizontal components dynamic excitation. A blind prediction was...
ABSTRACTModeling unreinforced masonry walls, subjected to seismic loads applied normal their plane, has received much attention in the past. Yet, there is a general lack of conformance with regard what aspects response computational model should reflect. Boundary conditions are certainly an important aspect, as can involve two-way bending or just one-way and, second case, along vertical horizontal directions. In this respect, flexural restraint wall intersections be significant addition size...
ABSTRACTEarthquakes cause severe damage to masonry structures due inertial forces acting in the normal direction plane of walls. The out-of-plane behavior walls is complex and depends on several parameters, such as material geometric properties walls, connections between structural elements, characteristics input motions, among others. Different analytical methods advanced numerical modeling are usually used for evaluating structures. Furthermore, different types analysis can be adopted this...
Abstract The destruction of Amatrice and the surrounding villages in Central Italy after 2016 seismic sequence was so impressive that engineers, authorities local communities started sharing common feeling historical stone masonry buildings were too below current safety standards. severe damage caused by earthquakes led to a general distrust traditional building techniques, leading conclusion there is nothing do but demolish rebuild, perhaps with false antique. Is an alternative? way combine...
Abstract When subjected to earthquakes, many objects or structural elements behave like rocking rigid blocks. Computer servers, medical shelves, art objects, statues, and electrical transformers are frequently included in this category. Protection of these is an important task, considering that their value could be inestimable operation crucial during earthquakes; base isolation technology has been proven a viable option for purpose. Initially, the dynamic model block placed on device...
The equation of motion a one way (vertical) spanning strip wall, as an assembly two rigid bodies, is presented. Only degree freedom needed to completely describe the wall response bodies are assumed be perfectly rectangular and allowed rock but not slide horizontally. Furthermore, no arching action occurs since vertical upper body restrained. Consequently, nonlinear, with non constant coefficients Coriolis acceleration term. Phenomena associated overburden self weight ratio, triggering,...
Out-of-plane response of unreinforced masonry elements is frequently the most critical aspect seismic performance existing buildings. The such usually governed by equilibrium rather than strength. Hence, it customary to resort rigid-body models, accounting for possible rotations, and/or sliding. However, results analyses depend on initial choice mechanism. In this article, shaking-table experiments a brick-masonry specimen, and stone-masonry specimen have been modeled resorting combined...
The 2016–2017 Central Italy earthquake sequence consisted of several moderately high-magnitude earthquakes, between M5.5 and M6.5, each centered in a different location with its own sequences aftershocks spanning months. To study the effects this on built environment impact communities, collaborative reconnaissance effort was organized by Earthquake Engineering Research Institute (EERI), Eucentre Foundation, European Centre for Training (EUCentre), Rete dei Laboratori Universitari di...
Summary In the out‐of‐plane assessment of rocking walls, a relevant and yet uncertain aspect is influence energy dissipated during motion due to impacts restraints, such as floor or tie rods. Therefore, in situ tests on unrestrained restrained unreinforced masonry made composite (rubble + blockwork) masonry, were performed analyzed. The restraint given by steel springs assigned stiffness, simulating connected full‐scale (4 × 1 0.6 m 3 ) specimens from dismantling building. are displaced...
The 2010–2011 Canterbury, New Zealand earthquake sequence caused extensive damage to unreinforced masonry churches. A sample of 80 affected buildings was analysed and their performance statistically interpreted. Structural behaviour is described in terms mechanisms affecting the so-called macro-elements, probability matrices are computed. Regression models correlating mean level against macroseismic intensity also developed for all observed mechanisms, improving initial simple-linear...
Abstract The main vulnerability models available in the literature aim to develop damage fragility curves estimate level suffered by a building after seismic event. However, recent earthquakes have highlighted great importance of predicting usability residential buildings, i.e. condition being habitable or occupiable performance can be used as an indicator for allocating economic funding event because researches demonstrated stronger correlation between repair costs and assessment rather...
Artistic masterpieces are mostly collected in museums located the center of urban areas, which prone to heavy traffic. Traffic-induced vibrations can represent a significant hazard for museum objects, due repeated nature excitation and brittle, pre-damaged condition artifacts. This is case Sarcophagus Spouses, displayed at National Etruscan Museum Villa Giulia Rome. Vibrations on floor room measured by means velocimeters, highlighting substantial vertical amplitudes recommending design an...
