Cantilevers are a part of our life, they everywhere: bridg–es, building’s balconies, traffic signs, car parking shades even the aircraft’s wings. The long cantilevers buildings always present as big challenge to structural engineers in their practice life. behavior these depends on several factors, such rigidity slab, columns or walls, span continuity... etc. But real dilemma lies economical ch...

The tensile force of pre-stressed concrete (PSC) girders is the most important factor for managing the stability of PSC bridges. The tensile force is induced using pre-stressing (PS) tendons of a PSC girder. Because the PS tendons are located inside of the PSC girder, the tensile force cannot be measured after construction using conventional NDT (non-destructive testing) methods. To monitor the...

Abstract A new bridge was built in Kalix, northern Sweden, to replace an existing prestressed concrete box‐girder that had been service for over 60 years. The old a total length of 283.6 m divided into five spans: 43.9 m, 47.0 94.0 and m. It constructed using the balanced cantilever method with segments having lengths around 3.0 need replacement arose from recommendations extracted assessment b...

Introduction . The purpose of the article is a generalized analysis existing methods for determining structural steel elements behaviour in extreme conditions subzero temperatures and their use to assess cold resistance beams prestressed by drawing thin wall. Subject study steel. Object bimetallic beam without rods. Materials based on mechanics deformable solid bodies, studies mechanical charac...
