Live load model for highway bridges *

Load models are developed for highway bridges. The models are based on the available statistical data on dead load, truck loads and dynamic loads. The paper deals mostly with the static live load. The model is derived from truck surveys, weigh-in-motion measurements and other observations. Simple span moments, shears and negative moments are calculated for various spans. Extreme 75 year loads a...

Calibration of a Congestion Load Model for Highway Bridges Using Traffic Microsimulation

For shortto medium-length bridges, the governing traffic loading scenario may be congested traffic. This paper presents the calibration of a congested traffic load model using traffic microsimulation. A range of bridge lengths, forms of construction, and load effects is considered. Different driving parameters and traffic composition are also considered. The influence of these parameters on the...

Recent Innovation for Concrete Highway Bridges

A new generation of concrete highway bridges has recently been built in Canada using new design concepts and advanced materials for reinforcing and prestressing concrete . This paper describes briefly the design and construction of three bridges. The first smart concrete highway bridge (Centre Street, Beddington Bridge, Calgary, Alberta) is prestressed by carbon fiber reinforced plastic (CFRP) ...

Fatigue Load Model for Highway Bridges in Heavily Loaded Areas of China

Fatigue is one of the main factors that cause the collapse of steel bridges. Anti-fatigue design therefore draws close attention all over the world. The design must have a fatigue load model based upon native traffic load conditions. But the Chinese steel bridge design specification does not include any fatigue load model for anti-fatigue design. So it is imperative to develop the model. This p...

Calibration of Load and Resistance Factors for Reinforced Concrete

Current approach for designing of reinforced concrete members is based on the load and resistance factor. However the load and resistance parameters are random variables, the constant values have been designated for them in the designing procedure. Assuming these factors as the constants, will be led to the unsafe and uneconomical designs. Safe designing of structures requires appropriate recog...
