Nonlinear Analytical Models for Interfacial Plug Stresses in Creeping Salt Formation
Analytical and numerical simulation models are presented which predict the nonlinear time dependent behavior of an expanding plug in a creeping environment heavily dependent on the storage...
Simulation of Salt Behavior Using In Situ Response
This paper presents an improved method for simulating the salt behavior. In this method, the governing equations are normalized to the creep function, which represents the transient and...
Creep Properties of Ice: Theory and Experiment
In recent years, intensive developments in Northern regions have increased the demand for solutions to a large number of engineering problems involving ice mechanics. In particular, these...
The Deformation Properties of Warm Underocean Permafrost
Two quasi-conventional incremental pressuremeter tests were carried out on man-made specimens of 'warm' ( minus 3 degree C) frozen, saturated sand. Instead of...
Sea Ice Indentation Accounting for Strain-Rate Variation
Two levels of ice loading are typically considered in the design of drilling and production platforms for the Arctic. Global ice pressures govern the overall structural geometry and dimensions...
Pile Creep Designs for Frozen Layered Profiles
A concept of relative creep stiffness suitable for the evaluation of the long-term, uniform creep behavior of non-ice type, frozen soils is presented. This concept extends the current...
Creep Rate Analysis of Pile Load Test Data
The uniform creep behavior of five driven piles and one slurried pile based on pile load test data are presented and analyzed. The incremental static load tests carried out by ARCO, Alaska...
Attenuating Creep of Piles in Frozen Soils
Results of several long-term creep tests of piles in frozen soils are analyzed; the primary or attenuating creep is predominant in most cases. For effective design of pile foundations...
Creep of a Strip Footing on Ice-Rich Permafrost
Creep settlement tests were performed on a strip footing founded on the surface of ice-rich aeolian silt permafrost. The tests consisted of applying four step loadings to a 10 in. (25....
Investigation of the Long-Term Creep Modulus for Buried Polyethylene Pipes Subjected to Constant Deflection
The tests reported in this paper are simulating the stress relaxation in constantly deflected pipe rings of various high density and medium density polyethylene grades. The pipe rings...
Effect of Voids on Creep Rate and Strength
The classic macroscopic Kachanov-Rabotnov model of material damage due to voids is reviewed. Detailed analyses of bulk mechanical properties of dilutely voided materials with certain,...

Application of Probabilistic Design to High Temperature Low Cycle Fatigue
High Rise Design: Accounting for Column Length Changes
In the late 1950's and early 1960's, the height of concrete buildings jumped from 20 to 60 stories. During the same period, architects introduced the use of exposed...
