FBM Materials - News

FBM Spa not only sponsors but technically and practically participates with researchers from the Department of Civil and Environmental Engineering of the University of Perugia in their experimental trials which seek to develop an anti seismic building system of construction through the use of confined masonry:

Muratura Confinata

Confined masonry construction consists of masonry walls made with semi hollow clay bricks or concrete block unit and horizontally and vertical reinforced concrete confining members built on all four side of a masonry wall panel which work as a single structural element and behave in a global and unified manner.
The terminology “confined masonry” comes from the fact that the masonry walls are built first and the reinforced concrete columns and beams are poured in afterwards to enclose (confine) the wall; this creates an active collaboration between the frame and the masonry walls. In traditional infilled frames is the walls that are built after the frame and are therefore not anchored to it.

The photo below shows two houses each built by using the two methods: the traditional and the confined masonry system. Both structures will then be placed onto a vibrating board in order to test and observe the dynamic behaviour of each structure.

To achieve this FBM has studied and developed a new block to build structures following this system. These blocks have been built in scale for the test..
