“…Many other international standards and recommendations exist, most of which indicate different limits for short-term and long-term vibrations, although they are variously defined (see [25][26][27][28][29]). In general, long-term limits, which are mostly related to urban traffic vibrations, are stricter, as they might generate fatigue and resonance problems in the structures in the long run.…”

The impact of long-term traffic vibration on ancient structures located in the city centre of big cities is an important issue, as it represents the main factor of fatigue, possibly causing structural damage in historic constructions. This article illustrates the preliminary results of a study on the so-called Temple of Minerva Medica in Rome, Italy, conducted within the CO.B.RA. project, which focuses on the development of advanced technologies and methods for the conservation of cultural heritage assets. The studied monument, which is part of the architectural heritage of ancient Rome, is located very close to several railway tracks just out of the Termini train station, on the northeast side, and to urban tramways, on the west side. To obtain indications on the dynamic behaviour of the structure and to map the base excitation induced by passing trains and trams, ambient vibration data were acquired by digital recorders with triaxial velocimeters positioned at several measurement points on the ground, around and inside the structure, and at different heights on the northwest façade. For evaluating the structural vulnerability, three-dimensional (3D) architectural surveys and non-destructive investigations on the material properties of the monument were conducted in order to implement a finite element model of the building to be used for structural analyses and dynamic simulations. In particular, to the purpose of obtaining a detailed 3D model, laser scanner and stereo-photogrammetric acquisitions were carried out. Photographic acquisitions were also used to identify the crack pattern and to document the current state of damage. Vibration and 3D reconstruction data were acquired both in summer and in winter, along with thermographic images, for assessing the seasonal effects on the structural behaviour. All collected data were stored into an ad hoc friendly data repository accessible through the internet by the accredited project end-users.

“…Thus, much more conservative vibration control limits are required to protect historical structures against blast vibrations. To ensure safety of historical structures against blast vibrations with lower predominant frequencies (<10 Hz), several investigators and agencies (DIN-4150, 1984;IS-14881, 2001, Konon andSchuring, 1985;Gupta et al, 1992) have proposed safe vibration levels in the range of 2 mm/s -6.25 mm/s. The IS Code (IS: 14881-2001) recommends frequency dependent safety criteria for protection of different type of structures against vibrations due to blasting.…”

Underwater drilling and blasting used for rock dredging is associated with several unwanted effects having potential to cause damage to surrounding structures and environment. Though all these ill effects can't be completely eliminated, using controlled blasting they can be minimized to acceptable levels. Underwater drilling and blasting was used for about 25,000 m 3 of hard rock dredging during construction of a Second Liquid Chemical Berth by Mumbai Port Trust (MbPT), Mumbai. The rock formation at the site mainly consists of basalt with compressive strengths varying between 16.04 MPa and 37.96 MPa. The average depth of required excavation was about 2 m. The Elephanta Caves, a World Heritage Site is located about 2.6 km from the proposed site. It was apprehended that ground vibrations resulted from rock blasting may endanger the safety of Elephanta Caves as well as other structures located nearby. Controlled blasting was used to ensure safety of various structures and its efficacy was established by monitoring of blast vibrations on different structures during actual blasting. The use of small quantity of explosives confined in blast holes, non-electrical delay detonators and initiating each hole with a separate delay, helps in minimizing the ground vibration effects on surrounding structures and complete the rock dredging safely in time.

“…Long-term exposwe to vibrations induced through overflight activities and sonic boom have the potential to affect standing historic structures and increase the rate of their natural degradation (Sources: Ellis, 1987;Konon and Schuring, 1985;Hershey et al, 1975 In general, the recreational resources of the land Gthdrawals are not as great as those elsewhere in the southern Nevada region; for example, Red Rock Canyon and the Toiyabe National Forest (Source: DOI/BLM, 1979a). However, the-land withdrawals have precluded the use of more than 3 miIlion acres of undeveloped lands in proximity to the largest population center in the State.…”
