Composting: Computing the Right Recipe
A pinch of this and a pinch of that is an adequate instruction for most good cooks. But for composting, facility managers need a recipe that specifies the right ingredients and exact amount,...

Soil Nails as Temporary Powerhouse Support
Newcastle Powerhouse was constructed as an underground structure with its top deck at the finished ground surface. The powerhouse is three-quarter circular and one-quarter square in plan....

Rio Moquino Stream Stability and Erosion Protection, Jackpile Uranium Mine
The uniqueness of the Jackpile Reclamation Project and the changes in reclamation technology over the past few years have prompted a reexamination of some of the design criteria specified...

Damage to Piles by Liquefaction-induced Ground Diplacements

Ductile Frames Are Tough for Earthquakes
Implications of a new structural system in wharf design go far beyond San Francisco Bay, where two such wharves remained intact after the 1989 Loma Prieta quake. The design, introduced...

Lateral Load Test on Driven Pile Footings
The October 17, 1989 Loma Prieta earthquake provided an ideal time and situation to perform for the first time, at no installation cost, a full scale lateral load test on a group of driven...

Environmental Wave Barriers for Small Craft Harbors
This paper describes the history and development of the environmental wave barrier and the current planning and design being undertaken for a major expansion of the small boat harbor at...

Load Sharing Benefits of Composite Pile Systems
The paper develops design techniques which will allow piled systems to be extended into more onerous operating conditions. In storm events marinas always develop failure mechanisms at...

The Application of a Structural Analysis Program to Floating Dock and Guide Pile Design
The floating dock systems and guide piles used in marinas are often designed using over simplified analysis techniques. However, if the dock system is flexible or if either the soil conditions...

Pile Test for Earthquake Repair
Load testing for existing concrete piles was specified as part of a seismic retrofit at the Port of Oakland after the Loma Prieta event. The Port wished to use heavier cranes at cargo...

Bayesian Updating of Axial Capacity of Single Pile
The paper outlines a Bayesian technique to update predictions of pile driving and axial pile capacity on the basis of pile driving records. The approach enables one to systematically account...

Probabilistic Evaluation of the Performance of Axially Loaded Bored Piles
Probabilistic evaluation of single slender elastic elements, bored piles, in a multi-layered soil system without noticeable displacement of the soils are considered. The numerical analyses...

Reliability-Based Design Requirements for Foundations of Buildings Subjected to Earthquake
Optimum seismic design coefficients and safety factors with respect to shear and overturning failure modes are obtained for a set of multi-story frame buildings idealized as single-mass...

Cellular Sheetpile Bulkheads

Cellular Sheet-Pile Floodwall in Cohesive Material at Williamson, WV

Design and Performance of a Deep Excavation Support System in Boston, Massachusetts

Initiation and Laws of Motion of Debris Flow
The mechanism of initiation and laws of motion of debris flow are studied experimentally, by allowing water or clay muds, with different clay concentrations and at different flow rates,...

Evaluation of the ARS Low Drop Grade Control Structure
The ARS low drop grade control structure was developed by Little and Murphy to provide efficient energy dissipation and effective grade control for streams in northern Mississippi. The...

Decayed Timber Bridge Microcomputer Rating Program
National Bridge Inspection Standards (NBIS) require that capacity ratings for each bridge structure be established. This requirement includes timber bridges which are often decayed, have...

Replacing an Urban Foundation
Baltimore's new subway extension will pass close to a 6-story reinforced concrete building near the Inner Harbor. Its timber piling foundation was threatened by the dewatering...
