Characteristic traffic load effects from a mixture of loading events on short to medium span bridges
In recent years, highway bridge load assessment has been recognised as an area through which savings can be made by avoiding unnecessary bridge refurbishment and replacement. Load effects in bridges result from single truck crossings or multiple-truck presence events which are, statistically, not identically distributed. Conventional approaches fit statistical distributions to mixtures of non-i...
متن کاملLong Span Bridges
Population growth followed by the dramatic increase and demand for new services created an urgent and overwhelming need for infrastructures of civil engineering structures. However, the current infrastructure work using various techniques and conventional materials for construction will not solve the traditional and continuous deterioration of concrete structures due to corrosion of steel. One ...
متن کاملStatistical Analysis of Traffic Loads and Traffic Load Effects on Bridges
It is vital to ensure highway structures to cater for increasing demand in transport capacity. This involves the precise estimation of structural load-carrying capacity to withstand potential maximum load effects in residual lifetime. The scope of this research thus addresses estimation of traffic load effect. Many different methods have been used to model extreme traffic load effects on bridge...
متن کاملDisplacement monitoring of a Long-Span Arch Railway Bridge using Digital Image Correlation (DIC)
There is an escalating demand for condition monitoring enhancement of transport infrastructures worldwide. Bridges are of vital importance in transportation infrastructure and need such monitoring. In this research, a non-contact vision-based technique called Digital Image Correlation (DIC) was used to calculate the bridge displacements. A high frame rate camera with 4K capability was used for ...
متن کاملDynamic Reliability Assessment of Long-span Suspension bridges under stochastic traffic flow
For most existing bridges, supporting continuous traffic loads is the basic function. However, in addition to this load, bridges are exposed to environmental (Frangopol and Soliman, 2015 [1]), as well as various other complex loads, that are mostly random in nature, such as earthquake, flow-included loadings, wind and so on. All these loading conditions need to be considered and must satisfy th...
