The preservation and definition of the correct retrofitting interventions historic masonry buildings represents a relevant topic nowadays, especially in country characterized by high seismicity zones. Considering Italian Cultural Heritage, most these are constructed ancient unreinforced (URM) showed level vulnerability during recent 2009 (L’Aquila), 2012 (Emilia Romagna) 2016 (Centro Italia) ea...

This paper investigates a seismic retrofit technique that allows bridge steel truss piers to uplift and rock on their foundation. Displacement-based passive energy dissipation devices buckling-restrained braces, or BRBs are implemented at the uplifting location to control the rocking response while providing additional energy dissipation. The hysteretic behavior of the controlled rocking system...

The most negative effects caused by earthquakes are the damage and collapse of buildings. Seismic building retrofitting repair can effectively reduce impact on post-earthquake priority to construction after being damaged an earthquake is perform assessment seismic traditional method mainly based visual inspection, which highly subjective has low efficiency. To improve intelligence assessments f...

ABSTRACT The majority of concrete buildings in the regions of high seismicity in Iran do not meet seismic code requirement, and many of these buildings are vulnerable in severe earthquakes. Concerns for seismic strengthening of concrete grew considerably in the recent years, and has been accelerated since the Bam earthquake 2004. This paper presents the results of experimental and analytical st...

Given the ambitious targets of carbon emission reduction set for very near future, it is now expected that retrofitting operations on existing buildings aim both at reducing their operational energy consumption and improving seismic performance. Indeed, well acknowledged that, if a sole efficiency upgrade provided to given building, in case an earthquake occurrence, double economic environmenta...
