After the seismic events of 20th and 29th May 2012 in Emilia (Italy), most monumental historic buildings area were severely damaged. In a few structures, partial collapse mechanisms observed (e.g. façade tilting, out-of-plane overturning panels…). This paper presents case-study bell tower Santa Maria Maggiore cathedral, located Mirandola (Italy). The dynamic response structure was evaluated through operational modal analysis using ambient vibrations, consolidated non-destructive procedure...
A major weakness among loading models for pedestrians walking on flexible structures proposed in recent years is the various uncorroborated assumptions made their development. This applies to spatio-temporal characteristics of pedestrian and nature multi-object interactions. To alleviate this problem, a framework determination localised forces full-scale presented using wireless attitude heading reference systems (AHRS). An AHRS comprises triad tri-axial accelerometers, gyroscopes...
The heritage of existing road infrastructures and in particular bridges consists structures that are approaching or exceeding their designed service life. Detrimental causes such as aging, fatigue deterioration processes other than variation loading conditions introduce uncertainties make structural assessment a challenging task. Experimental data on performances crucial for proper calibration numerical models able to predict behavior life-cycle performance. In this scenario, an experimental...
Summary This paper investigates the dynamic response of three sample buildings belonging to Seismic Observatory for Structures, Italian network permanent seismic monitoring strategic structures, managed by Department Civil Protection. The case studies cover different building types that could loosely represent stock, with a special emphasis on cultural heritage and masonry structures. Observed under low‐intensity swarm comprising about 30 aftershocks after main event, are analysed through an...
With the main focus on safety, design of structures for vibration serviceability is often overlooked or mismanaged, resulting in some high profile failing publicly to perform adequately under human dynamic loading due walking, running jumping. A standard tool inform better design, prove fitness purpose before entering service and retrofits modal testing, a procedure that typically involves acceleration measurements using an array wired sensors force generation mechanical shaker. critical but...
The Kashima Lighthouse, one of the lighthouses that suffered damage in 2011 Great East Japan Earthquake, required a careful investigation to estimate its long-term behavior and seismic vulnerability. This study, therefore, undertook meticulous process dynamic testing, identification, structural health monitoring Lighthouse. results tests reveal fundamental frequencies Lighthouse are estimated be around 2.60 Hz 2.63 east–west north–south directions, respectively. natural modes damping factors...
A multi-scale and multi-object interaction phenomena can arise when a group of walking pedestrians crosses structure capable exhibiting dynamic response. This is because each pedestrian an autonomous system displaying intricate behaviour affected by social, psychological, biomechanical environmental factors, including adaptations to the structural motion. Despite wealth mathematical models attempting describe simulate coupled crowd-structure system, their applicability generally be...
Structures may be subjected to damage and deterioration over different timescales, monitoring their health status allow perform maintenance actions before the functionality limit is reached. Masonry arch bridges, in particular, are sensitive bearings loss produced by scour of streambed soil at pier foundations. In this study, we measured changes elastic properties a 1:2 scaled model masonry bridge built laboratory study evolution mechanism related application foundation movements....
The aim of this study is the analysis and comparison several sets features selected from different domains for detection damage induced by scour on historical bridges. A scaled experimental model a masonry arch bridge was subjected to differential settlements pier simulate occurrence events. Damage states increasing extent were introduced verify sensitivity each feature accuracy method. vibration measurements acquired after step using sensors located in positions structure sources...
An innovative base isolation system has been recently proposed for the retrofitting of existing buildings, in which layer is inserted under building foundations so that building, along with its foundations, isolated from surrounding soil.The resides closely-spaced micro-tunnels, constructed entire width building.These trenches around isolate structure execution these micro-tunnels most critical construction stage, because it may result settlements can damage structure.In this paper,...
This paper aims at describing the tests campaign carried out on five precast bonded post-tensioned concrete bridge beams, recently dismounted after a service life of 50 years. The girders were part deck viaduct an Italian motorway. beams showed different deterioration levels, mainly due to exposure corrosive agents. test designed for evaluating residual load bearing capacity members. Dynamic measurements acquired before and static by using excitation sources. experimental research highlights...
The current trend in structural health monitoring (SHM) is to install increasingly large numbers of distributed, heterogeneous types sensors, for a timely and exhaustive detection any possible damage scenario evolving the system. These sensors should be low-cost, easy install, robust durable. Among others, strain remains one most straightforward measurands state element assessing its condition. However, application reinforced concrete structures, currently available sensing devices, such as...
For the analysis and conservation of architectural heritage a multi-disciplinary approach is required. In specific case early concrete buildings, survey experimental investigations constitute fundamental source information for verifying actual structural behavior residual safety levels. This paper reports direct experience acquired from an extensive campaign conducted on Paraboloide in Casale Monferrato. The study aims to be example how condition assessment 1900s, with apparently simple...
