Analysis of Geometric Mispositioning in a Vertical Pile Group
A straightforward procedure is described whereby an approximate, three-dimensional, nonlinear model for the analysis of pile groups is used to simulate errors in major group parameters...
Scour Around Cylindrical Piles Due to Wave Motion in the Surf-Zone
The paper discusses the results of experimental tests to study scouring phenomena around cylindrical piles during a sea storm with reference to the modelling of a beach profile in the...
Modelling of Cross-Shore Flow and Morphology
A one-dimensional, time-dependent model is presented which describes the evolution of wave groups and associated long waves over an arbitrary profile, in a short-wave averaged sense. Model...
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....
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...
Response Surface Fitting in Offshore Structural Design
Failure probability estimation of complex offshore structures requires the modeling of the system behavior in terms of all uncertain parameters. This paper investigates the applicability...
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...
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...
New Wharf Covers Trident Submarines
The U.S. Navy's newer fleet of Trident-class submarines requires upgraded support facilities. Work has continued on expanding the base at Kings Bay, Georgia. The explosive...
Expressway Centerpiece
The center span of the Napoleon Bonaparte Broward Bridge, better known as the Dame Point Bridge over the St. Johns River at Jacksonville, Fla., is the country's longest cable...
An Optimal Design of Steel Pipe Pile Foundation
This paper presents an optimal design method for the steel pipe pile foundation of bridge pier using a nonlinear programming. It is firstly assumed that an imaginary wall model behaves...
Performance of Steel Sheet Pile Cellular Cofferdams
Steel sheet pile cells are often used as construction cofferdams for structures to be constructed in rivers. Examples of this type of construction include locks and dams, pumping stations,...
