Alyeska Reroutes Trans-Alaska Pipeline at MP 200
This paper discusses the 1985 wintertime repair/reroute to the Trans Alaska Pipeline System (TAPS). The rerouted pipe was approximately 4000 feet long and cost approximately 27 million....

Finite Element Modelling of Cold Regions Concreting
Finite element heat transfer computer programs are discussed in regard to their use in modelling cold weather concreting. The concrete material properties required for input to the finite...

The Evolution of a Factory Insulated Piping System
This paper reviews the developments over the past fifteen years in a factory insulated high density polyethylene piping system that has become a standard for sewage and water piping systems...

Finite Element Analysis of Concrete Armor Units Subject to Wave Impact
Concrete armor units are commonly employed for the protection of shorelines and rubble structures. Their design is primarily based on hydrodynamic stability. However, their structural...

Optimal Design of Continuous Prestressed Concrete Girders
Design of continuous prestressed concrete girders with possibility of parabolically varying depth in each span is formulated in the form of a mathematical programming problem. The design...

Finite element formulations for analysis of the overall response of concrete bridge girders prestressed with external tendons is described. The analytical procedure includes several nonlinear...

Analysis of R/C Slab Under Turbine Missile Impact
Turbine missile impact on reinforced concrete barrier in nuclear reactor power plants is simulated using the finite element method. One of four full scale turbine missile impact tests...

Interactive Design of Reinforced Concrete Foundations
A new, highly graphical foundation design program, FOUNDATION-3D, provides the designer with a variety of easy to use foundation design tools in a flexible interactive environment. It...

Integrated Design of Concrete Flat Plate Structures
An integrated structural design and drafting system for concrete flat plate floor systems is described. This system provides at a single computer workstation the tools necessary to layout...

Finite Element Analysis of R/C Frames and Frame-Wall Systems
A finite element program has been developed for the analysis of reinforced concrete two-dimensional structures. The element library of the program includes, in addition to standard beam...

Nonlinear Analysis of RC Panels Under In-Plane Loading
A new concrete material model based on a modified Mohr-Coulomb criterion is proposed for the nonlinear analysis of reinforced concrete panels. Emphases are made on the softening behavior...

Analysis and Design of Prestressed Concrete Spun Poles
A microcomputer package for the analysis and design of prestressed concrete spun poles is described. The package, named PCPAD, consists of six programs each having a specific analysis...

Practical Modeling of Bar Slippage in R/C Joints
A procedure based on the displacement method of analysis has been developed for analyzing the behavior of beam reinforcement crossing the interior beam-column connections under seismic...

Scenic Squeeze
Constructing a four-lane dual highway through the 12 miles of Colorado's Glenwood Canyon involves several engineering innovations: cantilevered roadways, unusual retaining...

Transitioning End Terminal A TREND^tm for the Future
The highway engineer frequently starts from a position where an identified highway element is causing serious injuries or fatalities to motorists on the nation's highways....

Rowes Wharf: A Case Study in Substructure Innovation
Rowes Wharf is a project with many unique features. This paper has attempted to briefly review just one of these features - Up/Down construction. The willingness of the development team...

Demands for Innovation in Power Construction
This paper identifies some specific demands for innovation on power projects, reviews the alternatives considered to meet project objectives, and describes the resulting innovations. Examples...

Systems Model for Water Supply Following Earthquakes
The water supply for San Francisco is described with emphasis on the city's auxiliary water distribution network, which provides fire protection for the most heavily built-up...

The Effects of the 1985 Mexico City Earthquake on Underground Water & Sewer Pipelines
The 1985 Mexico City Earthquake left thousands dead and many thousands more without shelter. The visible damage was immense and terrible, and familiar to people around the world through...
