Abstract: This paper reviews the code development procedures used for the new load and resistance factor design (LRFD) bridge code. The new code is based on a probability-based approach. Structural performance is measured in terms ...

Abstract: The evaluation of existing bridges has received little attention in the structural reliability literature, yet probabilistic methods allow the evaluation of the adequacy of a structure better than deterministic analysis. ...

Abstract: Proof load tests were carried out on three deteriorated steel girder bridges with simple supports. Selected bridges are more than 60 years old, and their span lengths range from 11.0 to 15.5 m. Two military tanks were used ...

Abstract: This paper deals with distribution of truck load on girder bridges. Previous analytical studies based on finite-element method indicated that AASHTO code-specified girder distribution factors (GDFs) are inaccurate. In ...

Abstract: This paper presents the procedure and results of field tests that were performed on two simply supported steel I-girder bridges to assess girder distribution and impact factors. The measurements were performed under normal ...

Abstract: Twenty-five years ago, a bridge live-load model was developed along with the calibration of the AASHTO LRFD Specifications. The statistical parameters of truck loads were based on the Ontario, Canada, truck survey performed ...

Abstract: Cold‐formed channels are joined by means of spot welds to form various configurations. They are used in typical electrical cable and conduit supports, also in power plants. The present design procedures follow AISI ...
