Original caption: "IN THE NEW LABORATORY OF STRUCTURAL ANALYSIS Model structures are becoming more and more important in engineering research, not only as a means of checking theories but as stimulating visual aids to teaching. This truss bridge model in the new laboratory of structural analysis in the Department of Civil and Sanitary Engineering is used to study the structural action of bridges of this type. The importance of advanced studies in this field is indicated by the fact that recent experiments on truss bridges suggest they do not behave in strict accordance with design theory. In the model shown, the loads are applied by means of a hand wheel beneath the truss, the reactions are measured on a platform scale, and the resulting distortions of the structure are determined by dial gauges. The analytical and experimental data are then compared."
