Estimation of Design Freezing Indices
A method for arriving at a rational estimate of the design freezing index for any place on the Canadian Prairies is described. A correlation between mean annual temperature, mean freezing...

Gravity and Surface-Load Stresses in Spheres
Stresses due to gravity are reported for a solid sphere and for a hollow sphere with an inner diameter one-half its outer diameter. The stresses were obtained using the freezing method...

Estimation of Pavement Surface Freezing Indices
A rational and usable correlation between the freezing index values determined from air temperatures and from pavement surface temperatures has been developed. Data for the study were...

Estimation of Climatic Parameters for Frost Depth Prediction
A realistic method for estimating air freezing index, duration of freeze, and mean annual temperature for any latitude and elevation in West Virginia is presented. The method was developed...

Limit to Navigation by Ice in the Port of Churchill
The Port of Churchill is closed to navigation by the passage of frazil and slush ice prior to the general freeze up of its sea approaches. The investigation shows that the navigation season...

Experience with Prototype Energy Dissipators
A large number of replies from 200 questionnaires, distributed to obtain all the information possible on experience with prototype stilling devices at dams, indicated that no damage or...

Freezing and Thawing Effects on Prestressed Concrete

Extended Frozen Stress Method
Method facilitates photoelastic study of thin members in compression, and permits, in connection with conventional method, evaluation of influence of Poisson's ratio on stress...

Ventilated Building Foundations in Greenland
In permafrost areas soil supports foundations of structures only if permafrost can be prevented from thawing; use of air vents in foundation slab connected with ventilating stacks to secure...

Control of Ground Water in Excavations
Review of basic principles and methods of controlling ground water in excavations; decision upon application of conventional methods on special methods such as freezing, grouting, and...

Soil Freezing to Reconstruct a Railway Tunnel
Track rearrangement in railway tunnel in Montreal, was made difficult by maze of underground facilities, and by fact that work had to be performed under street between 2 buildings; aspects...

Physical Studies of Santa Barbara Storms
Physical measurements made during Santa Barbara program include radar with PPI and RHI scanning, atmospheric potential gradient, raindrop-size distributions, freezing nuclei concentrations,...

Freezing and Thawing Effects on Prestressed Concrete
Freeze and thaw test were conducted on 48 specimens representing strength levels of 5000 and 3000 psi; some of beams with 5000 psi strength were post-tensioned throughout test; significant...

Ventilated Building Foundations in Greenland
In permafrost areas soil supports foundations of structures only if permafrost can be prevented from thawing; use of air vents in foundation slab connected with ventilating stacks to secure...

Freezing of Slurry Around Piles in Permafrost
In Arctic construction, piles are frequently placed in drilled holes in permafrost and held in position while slurry of sand or silt and water is poured into space around them; analysis...
