Abstract:
In the introduction, the significance of the various concrete strengths, such as compressive, flexural, tensile, shearing, torsion, impact, bond, combined and fatigue strengths, is discussed. The two prinicpal reasons for determining the strength of a bridge concrete are as follows in the rest of the report.

This paper presents the analysis of the strains measured during the lowering of the bridge superstructure, when the prestressing of the bridge occurred. The calculated strains were based on the normal assumptions of composite behavior of the steel girder and the reinforced concrete slab.

Recently, when constructing railway bridges on existing Japanese National Railways we have found it more practical to take advantage of the application of composite girders to bridges, in view of the case of construction, maintenance and repair. However, this type of bridge has not yet been applied to such a high cyclic load as 5 x 106 in Japanese National Railways. . .The conditions to be considered in design and concstruction of this tpye of slab or girder in railway bridges are described. . .

This report deals with the general behavior of 'pre-deflected' composite steel-concrete beams under static instantaneous and short-term sustained loads. The effects of varying predeflection stress, shrinkage, creep and cracking on the performance of these beams are investigated.

This paper presents the results of a series of tests on fatigue of model prestressed and reinforced concrete bridge slabs of different span to width ratios and different prestress levels in the transverse direction.
