Corrosion of reinforcement is a major problem affecting a large number of reinforced concrete structures. At present, most reliability-based design studies of reinforced concrete structures do not consider the effects of corrosion. In this paper, we present a reliability-based approach to the design of reinforced concrete bridge girders that are under corrosion attack. Both reserve and residual...

Chile is exposed to the occurrence of medium- and large-magnitude earthquakes. As a result, national international design codes have been developed, whose objectives are grant an ideal behavior structures. However, in Chile, many these structures do not comply with construction standards current regulations. Therefore, we propose carry out historical compilation that allows establishing compone...

Metal magnetic memory testing (MMMT) is a nondestructive technique that can detect early signs of damage in components. Many scholars have studied the effect uniaxial stress on self-magnetic-leakage field (SMLF)’s strength. Nevertheless, there still insufficient research combined action bending and shear. We law distribution signal, ?HSF(y), at different parts steel box girder quantitative rela...

Accidental damage to prestressed concrete bridge girders may occur due impact by over-height vehicles on the bottom of girder, or top flange girder be damaged during deck removal and replacement operations. Since stress checks at service loads are an important component design for beams, serviceability-based should considered when assessing structural condition girders. In this paper, step-by-s...

Abstract Keramasan Bridge 2 is a bridge with an age of more than 30 years, so it necessary to review its feasibility and serviceability. Based on visual observations, there are signs cracks in the transverse longitudinal directions floor. results loading test, stated that deflection girder has exceeded allowable deflection, cause floor crack caused by non-uniform vertical movement girder. this,...
