Highway Bridge Impact Studies using A Simple Load Model

Chan, Tommy H.T. (1993) Highway Bridge Impact Studies using A Simple Load Model. In 4th East Asia-Pacific Conference on Structural Engineering & Construction, Seoul, Korea.

Abstract

This paper suggests a simple load model in which each axle load consists of a constant load plus a sinusoidally varying component. Field tests have been carried out to measure the impact fraction, I, for Six Mile Creek bridge, an 11.28 m span composite steel and concrete girder bridge. The field data have been used to calibrate the simple load model. This model has been used to predict upper bound values of I for bridges of varying span, with this dynamic component set at 4, 6, and 10%. The resulting values are larger than those that have been commonly used, particularly for shorter spans.

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
