A Multiple Presence Load Model for Bridges
This paper utilises weigh-in-motion data to simulate multi-lane traffic crossing short span multiple-lane bridges. In this manner the reduction factors for a multiple lane bridge are derived....

On the Fatigue Loading for Local Components
Fatigue provisions in the North American Codes for design of highway bridges may not be applicable to the design of local components which are subjected to high axle overloads and dynamic...

Live Load Models Based on WIM Data
The objective of the paper is to present the results of weigh-in-motion (WIM) measurements carried out in Michigan. Selected bridges were instrumented and truck weights and axle configurations...

Highway Construction and a Trout Stream Relocation
In 1970, a ten-mile section of Traffic Route 15 in the northern portion of Lycoming County extending into Tioga County was under design as a two-lane limited access highway on four lane...

Probability of Bridge Failure Due to Pier Scour
Methods have been presented for computing the probability of bridge failure due to pier scour either using a maximum scour depth model or a time-dependent model. The probability of failure...

Analytical Hydraulic Modeling of Road Culverts
This paper summarizes the development of a comprehensive analytical methodology and a computer model capable of simulating a wide range of flow phenomena in road culverts. The new flow...
