Structural safety is one of the most relevant issues within the civil society. Numerous structures require structural reinforcement interventions and many are the seismic events that have affected and continue to affect the Italian territory over the years. It is therefore a clear need to ensure structural performance in respect of current technical laws and numerous earthquakes.
In this context, the use of composite materials, consisting of high mechanical strength fibers and polymeric resins, represents an innovative technology compared to traditional consolidation systems, ensuring countless advantages both from the technical point of view that practical.
The FRP materials, in fact, thanks to the high mechanical strength and low impact on the structures in terms of weight, stiffness and geometry, represent an effective solution for the consolidation of concrete, masonry, wood and steel structures. The absence of oxidation phenomena, also, ensures high durability of these systems, eliminating the critical aspects typical of traditional methods.
The application of this technology field is very wide; in particular, in this case it is focused on the improvement and seismic upgrading of degraded existing structures or on the local reinforcement of individual structural elements. Interventions possible with FRP systems are numerous; they guarantee the structures high ductility and strength.
The Olympus-FRP line offers a wide range of resins and carbon, glass, basalt, aramid and steel fiber textile available in various weights and different frameworks. The pultruded laminae of carbon fiber are available in numerous sizes and elastic modules, also pultruded rods made of carbon, glass and aramid fiber are present with a wide range of products.

Highly topical issue is the security of public and private buildings also as regards the elements not directly linked to the support structures, which, however, may determine risk to the safety of persons. Recent seismic events have caused huge damage with socio-economic repercussions. Not only human life was put at risk but the country’s economy and its historical and architectural heritage was damaged in the face of considerable economic resources necessary for the restoration of entire areas affected by these catastrophic events.
In that regard, this category of intervention is very useful as it provides immediate solutions in order to prevent possible damage. In the time the increase of the structural strength, the acting on those parts of the building which can contribute to the load bearing capacity, has been the main technique, but, especially in recent years, it is evident the importance of all those elements that very often do not contribute to the load bearing capacity of the structure and therefore are considered non-structural in the calculation model. These are pots, partition wall and secondary elements, which, although not directly connected to the load-bearing capacity, can cause loss of human lives and economic terms. These elements were the source of collapses that led to uninhabitable condition of buildings and losses and risks to human life.
The proposed system includes techniques that must be implemented in order to combat phenomena of detachment of structural element or of elements like pots, cement floor, etc, systems in order to prevent kinematic mechanisms out of the plane of the walls as the overturning of more or less extensive portions of partition wall ensuring an effective connection between the structural parts constituting the frame and the partition wall constituting the non-structural element. The systems proposed consist of bidirectional mesh made of high mechanical strength glass fiber with different weight, anchored to the structural elements (joists / beams and columns) by means of special connection systems.

Structural reinforcement with GFRP preformed mesh.
The artistic heritage of our country consists of numerous masonry structures, both as regards the private buildings and for the monumental structures. There are numerous structures requiring structural consolidation interventions and there are many earthquakes, which have caused damage to buildings, causing necessary recovery actions.
In order to ensure to masonry structures an adequate level of performance, OLYMPUS offers the new OLYMPUS STONE system that via the use of GFRP preformed mesh allows the increase of the mechanical characteristics of the masonry elements.
The consolidation systems obtained by means of the laying of the OLY STONE mesh line, allow to easily remedy the structural deficit situations affecting the vertical structures, unlike interventions realized with traditional materials, reducing invasiveness and high durability in the time.
