An evaluation of the triaxial compression test for the determination of the shear strength of soils
The stability of a soil mass against progressive failure, caused by the weight of the soil or superimposed loads may be predicted by comparing, at all points within the soil mass, the shearing, stresses caused by these ...
An evaluation of the direct shear method for determining shearing resistance of soils
The shearing strength of the soil not only controls the resistance to failure by sliding, but also influences the ultimate compressive loads which may be applied. The shearing resistance depends on the nature of the material ...
Design criteria for haunched rigid frames
The photoelaetic technique is applied to evaluate two methoda of design for single span, haunched rigid frames. A plastic model of a haunched rigid frame is uniformly loaded, and observed under polarized light. Photographs ...
A field method of determining soil permeability
The permeability of soil -- its capacity to transmit water under pressure -- may be determined by indirect or direct laboratory methods or by field methods. Most field methods are useful only below the water table, but in ...
The selective stimulation of respiration in mixed cultures of bacteria and protozoa
A study of the selective stimulation of respiration in the cultures of bacteria and protozoa, as found in a typical domestic waste water, was conducted in the Sanitary Engineering and Science Laboratory of The Rice Institute ...
A study of ultimate design as applied to rigid frames
The methods of analyzing rigid frames in present use are known to have many undesirable characteristics which are either directly or indirectly the result of limiting stress and strain to values below the proportional ...
