Abstract: Tunnel excavation in cohesionless soils implies the use of a temporary supporting structure prior to lining installation. This temporary structure has to couple safety and economy, and can be conveniently realized using ...

Abstract: In the field of reinforced-concrete (RC) structures, the use of fiber reinforced plastic rebars (FRP rebars) as an alternative to the steel reinforcements appears very promising, especially if such structures are exposed ...

Abstract: The use of composite materials in structural engineering is recent, and researchers need to investigate their behavioral features. Design criteria and methods have to be redefined, and several countries have already ...

Abstract: Negative bending moments arise near the intermediate supports in continuous beams; thus, when steel-concrete composite beams are considered, tensile stresses act on the concrete slab. As a result the structural response ...

Abstract: A better understanding of the bond behavior, which is one of the main behavioral aspects of reinforced concrete structures, is needed for fiber-reinforced plastic reinforcing bars, because tests have shown that the bond ...

Abstract: Tuff buildings are a significant part of the Mediterranean area and are to be preserved from a structural viewpoint especially in seismic areas. Over the past few decades, the interest in strengthening of historical tuff ...

Abstract: Column jacketing with fiber-reinforced polymer (FRP) composite materials has been extensively investigated in the last decade to address the issue of seismic upgrade and retrofit of existing reinforced concrete (RC) columns. ...

Abstract: Every year, several prestressed concrete (PC) bridge girders are accidentally damaged by overheight vehicles or construction equipment impact. Although complete replacement is sometimes deemed necessary, repair and ...
