Site Specific Traffic Load Models
نویسنده
چکیده
This paper describes work carried out to develop a method for considering actual traffic loads during bridge evaluation. This method is based on the use of load correction factors which have been determined using a probabilistic analysis of bridge loads and resistance. Load correction factors are selected as a function of site characteristics and used in order to modify load effects calculated using a design traffic load model. This approach enables the accurate evaluation of bridges which carry a known traffic. If this traffic is less aggressive than that assumed by the design loading code, an acceptable reliability may be verified for structures which are damaged or deteriorated, thus avoiding the need for strengthening or traffic restrictions.

متن کاملSimulating the Effect of Speed Humps on the U-Turn Traffic
Traffic simulation represents an effective tool for evaluating the suggested alternatives to enhance traffic conditions prior to their application in real sites. U-turn sections represent examples of the complicated sections that cannot be analyzed properly without applying microsimulation approach. Recently, in Iraq, speed humps were applied in prior to the merging locations and U-turn sectio...
متن کاملExperimental Determination of Dynamic Allowance for Traffic Loading in Bridges
Bridge codes adopt values for dynamic allowance in traffic load models that are necessarily conservative to cover for an entire range of bridges with different mechanical characteristics, boundary conditions, and the large number of uncertainties associated to the vehicle-bridge interaction problem. A further level of conservatism occurs due to the independent manner in which the governing stat...
