An overall view is given of a dividing flow with mean subcritical flows in all channels. Experimental observations of reverse flows or recirculation regions, hydraulic jumps and local flows at the junction are described in detail. Photographs showing these phenomena under different flow ratios are also presented. A surface discontinuity at the junction which is not known previously is a also mentioned. [...]

Two series of eight rectangular reinforced concrete beams without web reinforcement were tested under two symmetrical concentrated loads with the following variables: 1) percentage of longitudinal tension steel; 2) shear span to depth ratio. [...]

Settlement is a very important engineering problem which usually occurs when a buried soft clay stratum is loaded by a building or any kind of structure. In the laboratory, the method of estimating the amount and the rate of the settlement has long been developed; this test is called the consolidation test. [...]

Present day knowledge of soil strength is limited to conditions favouring static or quasi-static loading. Under these conditions, the shear strength parameters are as yet not well defined. Neither is there satisfactory agreement on the true mechanism of friction and cohesion in clay soils. For example, Rowe (1957) suggests that true cohesion may be unstressed at equilibrium and that creep would result if true cohesion is mobilized. [...]

During the development of modern scientific soil mechanics, more attention was paid to the behaviour of clays than to other types of soil (Aylmore and Quirk, 1959; Norrish, 1954, among others). It has been pointed out that physico-chemical factors are important in the prediction of mechanical properties of such soi1s (Rosenqvist, 1962; Lambe, 1960). [...]

The fact that a water hammer blow effect is experienced in an enclosed line when the water flow is stopped has been well known to engineers from as long ago as the 17th Century. However, until comparatively recent years, there has been no record of any attempt to solve the problem directly. The most common approach has been that of "solution by avoidance of the difficulty". [...]

Previous investigations have shown that treating a bridge as a single simple beam is inadequate in the analysis of most multi-girder highway bridges. The transverse distribution of deflection must be considered as well as the longitudinal distribution. [...]

An attempt is made to determine whether the interaction of pack ice and ocean waves can be studied usefully in a laboratory model. Ocean waves and ice floes are simulated by waves in a laboratory channel and by thin floating sheets of polyethylene. [...]

The movement of water through partially saturated soils is of continuing interest to engineers and agriculturists. Agriculturists are concerned with the provision of adequate moisture for proper plant growth and have directed their energies towards predicting moisture movement after allowing for gains from the water-table. [...]

Missing pages. / The occurrence of brittle fracture in steel has been known for many years and has been of direct concern to the engineering profession. In the last twenty years major failures of this type have occurred in a considerable number of important engineering structures and in a very large number of welded steel ships. [...]
