A framework for the evaluation of the structural safety of existing concrete gravity dams
… some research into the process of evaluating the structural safety of dams. The focus of this research study is specifically on the evaluation of the structural safety of large concrete gravity dams. The purpose of the research is to investigate the most commonly used and accepted methods to …

Effects of disparate information levels on bridge management and safety
… allows for risk-based approaches to quantify structural safety, which is largely seen as a superior approach than the deterministic methods typically used in practice. Structural safety can broadly be defined as an acceptable level of chance/probability that the structure will not fail in its …

Technical management of vlcc/vlbc hull structures based on safety case principles
… involving environmental damage caused by structural failures in ageing oil tankers and bulk carriers has highlighted the importance of structural integrity issues involving these types of ships. Between 1980 and 1996, there were 186 total losses of bulk and combination carriers and 1,278 …

Structural assessment of the Guastavino Masonry Dome of the Cathedral of Saint John the Divine
… is a need to better understand their history and structural safety. This thesis applies structural analysis techniques to assess the Guastavino masonry dome of the Cathedral of Saint John the Divine. This dome is incredibly thin with a L/t ratio of 200. Thus, it is important to assess this dome …

Calculation of smoke ventilation in building fires including atriums
… reducing the visibility, risking the egress safety of the occupants and endangering the operative action of the fire brigade. Furthermore, the structural safety, the property and the personal estate are also endangered by the heat and smoke. For these reasons, the movement of heat and smoke …

Ein Beitrag zur experimentell gestützten Tragsicherheitsbewertung von Massivbrücken
… for the experimental assessment of structural safety and usability of concrete structures. By now, the influence of pavement or floor layers and of other factors on the load carrying capacity is not known exactly. In this thesis, it has been investigated how road pavements, the …

Mechanical behaviour of steel hollow section columns subjected to damage – experimental study and finite element modelling
… Steel Sections (HSS) are integral components in structural and architectural applications, valued for their torsional resistance, versatility, and aesthetic appeal. These welded steel tubes are typically manufactured off-site and transported to construction sites. However, during transportation, …

Determining seismic response of mid-rise building frames considering dynamic soil-structure interaction
… design properly; the accuracy in assessing the structural safety, facing earthquakes, could not be reliable. Performance-based engineering (PBE) is a technique for seismic evaluation and design using performance level prediction for safety and risk assessment. Soil-structure interaction …

Behaviour and modelling of the inelastic response of concrete and steel-concrete infrastructures subjected to low-cycle fatigue
… In particular, in order to guarantee the safety of citizens, the seismic response of infrastructures under an earthquake requires a careful evaluation of the level of damage of structural elements. In this thesis, typical case studies are considered, such as a concrete tunnel lining and a …

Behaviours of steel connections with unfitted stiffeners
… connections are fundamental to the structural integrity and safety of steel-framed buildings. A critical issue arises when gaps exist between stiffeners and connected elements, referred to as unfitted stiffeners, which introduce uncertainties in the load-bearing capacity and …

Flexural models of reinforced concrete beams under blast load
Nowadays, the issue of structural safety under blast loading has become a dramatic problem. The tragic news of the terrorist attacks of recent years (9/11/2001, New York; 7/7/2005, London; 7/23/2005, Sharm El Sheik; 1/24/2011, Moscow; etc), raise important, urgent questions regarding the real …

Structural performance evaluation of concrete arch dams using ambient vibration monitoring and GNNS systems
… that their failure is avoided. To ensure the structural safety of these structures, concrete dams are continuously monitored by sensors installed on the dam to detect any unusual behaviour. Data collected by the sensors include environmental variables (temperature and water levels) and dam …

Machine learning-based stress-strain prediction and process parameter optimisation in material extrusion additive manufacturing
… response is essential not only for assessing the structural safety but also for guiding the design of printing parameters tailored to the application-specific mechanical requirements. Despite progress in empirical modelling and data-driven approaches, most existing methods focus on isolated …

Giudizio immediato sullo stato di degrado dei ponti in c.a. basato su indagini low-cost
The structural engineer is often involved to express an opinion on the state of efficiency of the existing structures. This is partly because, in Italy, a large part of structures was built before the middle of the last century. Indeed, the 14th General Census of Population and Housing in 2001, …
