Final Report of the Special Committee on Impact in Highway Bridges

The Committee was appointed in 1922, and was asked to search for available data on the subject of impact in highway bridges, to encourage experimental work in a more systematic manner than had yet been attempted, and to report to the Society concerning the available information and its application to the design of highway bridges. Subsequently, progress reports have been presented at each Annual Meeting and published in Procccdings. Two of these reports contain pertinent data of value. This report undertakes to present such conclusions as the Committee has been able to make from the available data; also, in the form of appendices, abstracts of such data as will assist those who are especially interested to make independent applications of the information and to direct future work along the most profitable lines.
