The Creeping Storm
During the past 40 years the U.S. Army Corps of Engineers has spent nearly a billion dollars constructing a barrier around the low-lying city of New Orleans to protect it from hurricanes....

Frozen Ground Engineering
This new edition gives a peerless presentation of soil mechanics for frozen ground conditions and a variety of frozen ground support systems used on construction project worldwide. An...

Losing Ground
Unusual engineering approaches, careful studies of earth and water movements, and a multi-organizational project team that worked cooperatively lead to the successful replacement of the...

Creeping Suspicion
High-capacity, epoxy-coated anchors were installed at Upper Occoquan Dam to increase the stability of the 70-foot-high concrete gravity dam and powerhouse under revised Probable Maximum...

Creep Analysis of Composite Steel-Concrete Members with Deformable Connectors
The long-term analysis of composite steel-concrete beams with elastically deformable connectors is presented. The basic integro-differential equation governing the problem is solved by...

Time-Dependent Load-Distribution Behavior of Parallel-Member Wood Systems
The effect of differential member creep on the load-distribution behavior of parallel-member wood systems is examined. Variability in the creep response of the individual component members...

The Slender Tower of 52-54 East End Avenue
The structural system for the 52-54 East End Avenue project is presented. The 40 story residential tower with as aspect ratio of 12: 1 is one of the most slender buildings constructed...

Creep and Shrinkage of Composite Columns in Tall Buildings
The simultaneous presence of steel and composite columns in tall buildings is a common occurrence. The axial shortening characteristics of composite columns are influenced by creep and...

Testing and Evaluation of High Capacity, Multi-Strand Rock Anchors for Lake Lynn Dam
Seventy five rock anchors with design loads of 556 to 2040 kips were required for the 1000-foot long, 125-foot high, concrete gravity, Lake Lynn Dam to comply with current FERC engineering...

Effects of Creep in Cable-Stayed Composite Bridges
The paper summarizes the various ways in which creep in the concrete slab may affect the stresses in a cable-stayed composite bridge. It explains one effect in particular which is not...

Numerical Integration of Transient Creep Constitutive Equations for Polycrystalline Ice
A numerical time integration algorithm is developed to solved the system of coupled, first-order differential equations characterizing the physically-based constitutive model of Shyam...

Serviceability Analysis of Wood Beams with Creep
The effect of creep deformations on the serviceability reliability of single, dimension lumber wood beams is examined. A viscoelastic stress-strain relationship is used to model the time-dependent...

Nonlinearities and Imperfections in Creep Stability
The effects of material and geometric nonlinearities and imperfections on the 'safe-load-limit' and the 'safe-service-period' of structures...

A Second Order Analysis Technique for Nonprismatic Bridge Piers
An approximate second order method is presented for the analysis and design of cantilever compression members. Prismatic members with nonconstant reinforcement, and nonprismatic members...

Moisture Diffusion in Concrete and Mechanisms of Drying Creep
The Pickett effect is the excess of creep at drying over the sum of shrinkage and basic creep. Several theoretical models have been presented to speculate on the mechanisms of this effect,...

A Time-Dependent Microplane Model for Creep of Cohesive Soils
The microplane model is used in this paper to describe the time-dependent (creep) behavior of cohesive soils (clays). The constitutive equations are defined on each of a set of microplanes...

Rate Effects in the Deformation of Rocks
This paper gives a brief review of creep and rate effects on the behavior of rocks, within a wide range of confining pressures and temperatures, and with a special emphasis on the physical...

Creep of Polycrystalline Ice
This paper discusses the extension of creep models for polycrystalline ice to include the effects of a non-monotonic loading history. Attention is focussed on cyclic loading since it is...

A Test Method to Evaluate Shrinkage Cracking of Concrete
The possibility of shrinkage for a given drying environment depends on the following factors: free shrinkage, creep, and age-dependent properties of concrete. A common way to account for...

Time-Dependent Behavior of FRP Lintels
This paper describes an experimental investigation into the short-term and long-term behaviors of two types of T-shaped lintels made of fiber-glass reinforced plastic with polyester or...
