Dynamic Wheel Loads from Bridge Strains

O'Connor, Colin & Chan, Tommy H.T. (1988) Dynamic Wheel Loads from Bridge Strains. Journal of Structural Engineering, 114(8), pp. 1703-1723.


Earlier impact studies on a small-span bridge under service loads gave impact fractions much higher than those specified by AASHTO. This paper represents the first stage of a program to identify the high-impact vehicles. It describes theoretical studies that use bridge measurements to estimate not only the equivalent static loads but also their dynamic variation with time. Acceptable estimates have been obtained. The use of measured bending moments gives better results than measured def1eetions. The correct selection of nodal spacing and arrangement is important.

Citation counts are 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.
