Bridge expansion joints require inspection and maintenance throughout their lives,and replacement at the end of these lives,and these activities result in considerable costs to the bridge owner and im
In the responsible management of any construction project or asset,life-cycle considerations must be to the fore.This is now widely recognised,even if this has,to a large extent,regrettably not yet tr
In japan,the very real social problem of the corrosion damage associated with aging has reared its ugly head in the case of steel bridges.Old bridges erected in previous eras used riveted joints,and w
This study concerns seismic vulnerability assessment of existing reinforced concrete (RC) bridges with a common structural scheme in Italy (multi-span simply supported girder bridges).Most of these br
Maintenance of bridge deck slabs is one of the most demanding tasks in management of road infrastructures because intervention of bridge deck slabs causing traffic disruptions should be avoided as muc
This paper introduces the development of a partially earth anchored (PEA) system which can be applied to a multiple span cable stayed bridge (CSB).A characteristic analysis on existing multiple span C
Reinforced concrete without protection may be damaged while exposed to the corrosive medium,which shall affect the safety and service life of the structure.Treating concrete surface with silicone wate
Stochastic and narrow band nature are the two essential features of lateral walking loading not addressed adequately in the existing design guidelines for pedestrian structures,such as footbridges,lon
Large-scale bridges are mainly located within the complicated atmospheric environment contaminated by aggressive agent and the reinforcement bars embedded within concrete components are in the possibl
Durability is always admitted as a critical issue for reinforced concrete structures.Usually,thickness of concrete protective layer is the major consideration in engineering practice for designers reg
