“…The challenge lies in the proper installation and validation before functional use 11 – 14 . Authentication of the newly installed SHM systems is extremely important for the start of their operational life 15 . Besides this, calibration of the SHM system is required which can be ensured by field load testing of bridge.…”

This research focuses on the automation of an existing structural health monitoring system of a bridge using the BIMification approach. This process starts with the Finite Element Analysis (FEA) of an existing bridge for the numerical calculations of static and dynamic parameters. The validation of the FE model and existing SHM system was carried out by the field load testing (Static and dynamic) of the bridge. Further, this study tries to fill the research gap in the area of automatic FE model generation by using a novel methodology that can generate a BIM-based FE model using Visual Programming Language (VPL) scripts. This script can be exported to any FE software to develop the geometry of the FE model. Moreover, the SHM devices are deployed to the Building Information modelling (BIM) model of the bridge to generate the BIM-based sensory model (as per the existing SHM system). In this way, the BIM model is used to manage and monitor the SHM system and control its sensory elements. These sensors are then linked with the self-generated (Internet of Things) IoT platform (coded in Arduino), developing a smart SHM system of the bridge. Resultantly, the system features visualisation and remote accessibility to bridge health monitoring data.

“…Monitoring of concrete structures can be defined as a procedure of systematic data acquisition based on a monitoring plan, which aim to detect changes in materials and/or structural properties. In a general sense, monitoring can be regarded as systematically performed testing [3], [18], [19], [20] . The monitoring systems are generally focused on detecting deterioration having as objective the evaluation of the structural performance in terms of structure safety (Ultimate Limit State, ULS), serviceability (Serviceability Limit State, SLS) and condition (Condition Limit State, CLS) [3], [21].…”

“…Monitoring of large constructions with high safety and durability requirements, such as bridges, tall buildings, bulkheads, tunnels, silos, chimneys, offshore platforms, is performed with the aim of verifying the hypotheses of the design, the calibration of an FEM model, the update of the technical specifications, as well as to evaluate the health of the structures, to detect the presence of any damage, to locate it, and to quantify its severity [1,2].…”

Periodic monitoring of large industrial and civil structures is carried out through static and dynamic measurements. The monitoring, carried out over many years, offers important information for evaluating the health of structures and their management. Dynamic tests are carried out starting from measurements of the vibrations of the structure induced by mechanical devices or by the surrounding environment. If a ground support element is available, it is possible to exert a forcing action on the structure using actuators fixed to the support. When a ground support is unavailable, the structure can be forced using devices comprised of masses with rotary or reciprocating translational motion. These masses must be large enough to excite appreciable mechanical vibrations of the structure. In this paper, a vibration exciter, based on a mass suspended on an air spring and forced to vibrate at the resonant frequency, is proposed. Thanks to the resonant condition, the force transmitted to the structure is amplified compared to that applied to the mass. The excitation frequency can be adjusted by altering the inflation pressure of the air spring to modify the natural frequency of the system. In the paper, after the presentation of some mechanical devices used as vibration exciters for large structures, the proposed device is described and the first experimental results are reported.
