Steel orthotropic bridge deck is the only system likely to provide a service life exceeding 100 years with minimum maintenance; however,concerns of inservice fatigue cracking from welded connections,and the consequent high initial cost owing to intensive fabrication demands,are the perceived challenges to effective life cycle cost for this deck system.

Dongshuimen Bridge and Qiansimen Bridge are the two bridges on rail transit line 6 across the two rivers,with highway and rail traffic dual functions.The two bridges are only 1.2 km from the city cent
When such unexpected earthquakes happen,infrastructures may collapse even if those are rationally and safety designed according to the current devised specification.Therefore,it is essential to catch

Maintenance of aging infrastructure is a burden on many organisational budgets,and Life Cycle Cost Analysis (LCCA) is accepted as an effective method to reduce these costs.However,LCCA becomes extreme
At present,due to the hidden troubles in scheme,design and construction,as well as Chinese basic condition "respect construction and despise maintenance",many problems have appeared in some just finis
A detailed study to assess the condition of existing highway bridges was carried out by establishing a multi-index comprehensive evaluation model.
The seismic-resistant design of structures,is generally performed under a unique ground motion excitation at the base,regardless its type,shape and planar extension.However,for extended structures,suc
Deterioration of steel cable-stayed bridges is often found in stay cables,steel girders and foundations.Structural durability problems mainly contain fatigue and erosion of the cables and steel girder
Structural characteristics are extremely important to the durability design process of concrete bridge,yet are not considered sufficiently by the design parameters in current durability design codes a
