Chapter
Guidelines describe the general process of in-situ compressive strength assessment. This process is divided into three main steps, data collection (using nondestructive testing and destructive testing), model identification and strength assessment. Three estimation quality levels (EQL) are defined depending on the targeted accuracy of strength asse...
Chapter
This benchmark aims to assess mean compressive strength at several scales and to identify the location and characteristics of possible weak areas in the structure. It concerns synthetic data simulated on a group of four concrete cylindrical structures of identical dimensions with different kinds of strength distribution, based on a real case study....
Chapter
A benchmark is carried out in order to compare how 13 experts define and can carry out an NDT investigation program and derive strength values from NDT measurements. The benchmark is based on simulations, which reproduces a synthetic data set corresponding to a grid of twenty 3m-high columns defining the structure of a building made up of beams and...
Chapter
The main objective of test region (TR) identification is to define an efficient conversion model. The first part of the chapter aims a difficult question, the identification of test regions (TR) because each structure is specific and so it is impossible to give a unique methodology. Here, three different possibilities are proposed. The first one is...

Macroseismic intensity data are an important source to learn from historical earthquakes. Nevertheless, this data needs to be converted into more suitable intensity measures to be used in risk analyses, as well as in design practice. To this purpose, in this paper, correlations between macroseismic scales and ground motion parameters have been deri...

In the aftermath of the Mw 6.0 August 24, 2016 Central Italy earthquake, the authors carried out a reconnaissance survey in the municipality of Amatrice and gathered extensive photographic evidence of damage, with emphasis on 37 reinforced concrete buildings located outside the historical centre. Damage distribution is generally represented by wide...

After the ML = 6.0 earthquake which occurred on 24th August 2016 in central Italy, some unexpected variability in the damage distribution were identified in many villages located around the epicentral area. In particular, despite a distance of only about 1300 m, the villages of Pescara del Tronto and Vezzano (both districts in the Arquata del Tront...

In this article, a framework of building monitoring is developed and transient and permanent variations of the fundamental period of vibration caused by both damage and repair interventions are investigated. The buildings of the University of Ferrara (Emilia-Romagna Region, Northern Italy), struck by the 2012 Emilia seismic sequence, were monitored...
Article
Strength assessment of concrete in existing structures is a key issue. Many non destructive techniques (NDT) are available which can provide information about the material condition and several approaches can be used to derive strength estimates from NDT test results. However, common practice suffers from many drawbacks: (a) it is difficult to asce...

One of the most critical issues in the management of post-earthquake emergency is the prompt identification of the most damaged urban areas. Rapid detection of damage distribution is crucial for Civil Protection during the management of the first emergency phase, in order to both address assistance teams and identify priorities in planning the usab...

of buildings in order to recommence daily life in the stricken area while ensuring the safety of people returning to their houses. Generally, this is done by means of surveys based on usability forms filled out by expert technicians. Different countries adopt different forms, all that assess usability in terms of building damage. The Italian approa...

The authors have surveyed many damaged villages located at the epicentre of the ML=6.0 earthquake which occurred on August 24, 2016 in central Italy. Some unexpected anomalies were discovered such as very different levels of damage in Vezzano and Pescara del Tronto villages (Arquata del Tronto Municipality, Ascoli Piceno province). The two villages...

Strength assessment of concrete in existing structures is a key issue. Many NDT techniques are available which can provide information about the material condition and many models can be used to assess concrete strength from NDT results, but there is no way to establish what is the level of accuracy/confidence of concrete strength estimates. Since...

Article
This paper deals with the development of a procedure aimed at defining a seismic risk mitigation strategy for public buildings in terms of prioritization, time required and funds. The procedure is based on a global risk index involving the entire building stock under study thus facilitating an examination of risk variation over time up to its final...

A damaging seismic sequence hit a wide area mainly located in the Emilia-Romagna region (Northern Italy) during 2012 with several events of local magnitude Ml ≥ 5, among which the Ml 5.9 May 20 and the Ml 5.8 May 29 were the main events. Thanks to the presence of a permanent accelerometric station very close to the epicentre and to the temporary in...

Since October 2010, a seismic swarm is affecting the Pollino mountain range (Basilicata and Calabria regions, southern Italy). While writing this paper the sequence is still ongoing, with more than 600 earthquakes perceived by the population having local magnitudes ML > 2.0. The population main fear is the risk that a destructive event could follow...
Article
This paper offers a case study of the seismic vulnerability assessment of existing buildings in 18 villages located in the Val d’Agri area (Basilicata region, Southern Italy). A building-by-building inventory was carried out within the urban areas of the villages by trained technicians in two periods collecting typological data for a total of about...
Article
Reinforced Concrete (RC) buildings can require the determination of in situ concrete strength during the execution of new structures to investigate low-strength results from acceptance tests and, especially, in the capacity assessment of existing structures. Most structural codes and technical recommendations indicate that in situ concrete strength...

This paper discusses the problem of validation of a proposed uniform European building database. It proposes a process for validation using a set of so-called "test-bed" sites in Europe in which detailed local building-by-building surveys have been made in the recent past in a variety of projects. It explains how the data from these studies has bee...

Facing natural disasters effects can be a very difficult task lacking suitable activities and tools to preventively prepare the involved community (people, authorities, professionals, …) to the expected events. Therefore, a suite of preventive actions should be carried out to mitigate natural risks, in particular working to reduce the territorial v...

The M w 6.3 L’Aquila earthquake of April 6, 2009 hit a wide area of the Abruzzo region (Central Italy). The epicentre of the main shock was very close to the urban centre of L’Aquila, the regional capital, with an epicentral distance less than 10 km. It was the strongest earthquake ever recorded in Italy which has provided ground motion recordings...
