Port of Kismayo (Somalia) Rehabilitation
Extensive deterioration of the 2070 ft long four-berth, marginal wharf at the Port of Kismayo necessitated a major rehabilitation to maintain operations. The selected scheme was a steel...
Overdredging at Existing Gravity Structure
Pacific Elevators Ltd. decided to upgrade Berth No. 2 to handle ships up to 70,000 DWT. The difficulty was to maintain the support of the cribs after dredging of the berth to minus 45...
Underwater Compaction of Sand Fill During Placement
A system and related equipment have been developed, and tested on a recent dredged fill project, to compact sand, either clean or with limited silt, in lifts several feet in thickness...
Seismic Design of Earth Retaining Wharf Structures
Seismic design considerations pertinent to earth retaining wharf structures are reviewed. These considerations include: evaluation of the seismic environment and design earthquake ground...
Marginal Wharf and Embankments?Seismic Design
This paper presents some of the seismic considerations used for the improvements at Berths 225 to 229 at the Port of Los Angeles. The design of the improvements was complicated by the...
Soil-Structure Interaction in Seismic Environments
Soil-structure interaction depends on the mass, stiffness and the damping of the structure as well as on the geometry and embedment of the foundation and on the properties of the soil....
Recent Advances in Structural Dynamics
The four papers in this book emphasize the design, testing, and analysis of large structures. The topics covered include base isolation in the design and construction of power plant structures,...
Dynamic Response of Structures
The primary goal of the third specialty conference on the dynamics of structures was to provide a forum for dialogue between engineers conducting experimental tests and those developing...
Tiebacks for Bulkheads
Tiebacks were once used primarily to support temporary structures such as supported excavations. However, the use of tiebacks has been gradually expanded to include the support of permanent...
Effects of Deterioration on Safety and Reliability of Structures
Deterioration of structural and non-structural elements in commercial, industrial and residential constructions is of general concern to investors, design engineers, architects, contractors...
The Mile High Dream
For the 1986 Tall Buildings Conference in Chicago, a group of experts studied the implications of a mile high skyscraper to be built of concrete. It is 500 ft square at the base, designed...
Bridge Management: Computer Aided Priorities
Pennsylvania's Department of Transportation has invested $3.6 million in developing the concept and software for a Bridge Management System that will help determine the needs...
Structural Analysis by Spreadsheet
This is an introduction to and description of use of a spreadsheet to analyze a two-way slab on a microcomputer. The spreadsheet used is Lotus 1-2-3, but the ideas generally apply to many...
Use of In Situ Tests for Foundation Design on Clay
Years of evaluated experience with the field vane test in soft clays have resulted in empirical correction factors well suited for design practice. An extension of L. Bjerrum's...
Seismic Cone Penetration Test
A new test, called the seismic cone penetration test (SCPT) is described. A small rugged velocity seismometer has been incorporated into an electronic cone penetrometer. The combination...
In Situ Testing for Lock and Dam 26 Cellular Cofferdam
The in situ testing consisted of split spoon and cone penetration tests, Menard and self-boring pressuremeter tests, and Marchetti dilatometer tests. The testing program proved to be challenging...
Borehole Shear Test and Slope Stability
Three Iowa landslides analyzed on the basis of Borehole Shear Test (BST) data are reported. The soils included CL and ML loess and glacial till, and CH clay shale. Back-calculations from...
Pressuremeter Correlations for Preconsolidated Clay
Conventional triaxial compression and consolidation tests are often utilized to obtain parameters for design of foundations. More recently, Menard pressuremeter test results have been...
ECPT Investigation of a Slurry Trench Cutoff Wall
ECPT (electronic cone penetration testing) was used to investigate a soil-bentonite backfilled slurry trench cutoff wall at Calamus Dam in Nebraska, The wall was tested shortly after its...
In Situ Tests Aid Design of a Cylinder Pile Wall
In situ testing was used to verify geotechnical design parameters and modify construction for a 22 million dollar slope stabilization project near a major highway interchange. The project...
