Lateral Load Tests of Piles in Sloping Rock Fill
A new container wharf constructed at the Port of Los Angeles features vertical prestressed concrete piles to provide both vertical and lateral support. A rockfill embankment used to allow...
Pile Foundation Design Using Pile Driving Analyzer
A case history of pile foundation design and construction for Pacific Bell's San Ramon Valley Administrative Complex is presented. Dynamic monitoring of driven piles with...
Role of a Standard in the Production of Drilled Shafts
The preparation of drawings and documents that describe the details of the installation of drilled shafts for a project requires an up-to-date standard. The role of the standard in the...
Geotechnical Perspective?Proposed Drilled Shaft Standard
In the writer's understanding, a standard is an agreed upon manual of practice and as such, sets the level of performance and attainment considered adequate. A standard is...
A Structural Engineering Perspective for Drilled Shafts
This commentary is an attempt to close the gap between the Building Code Requirements for Reinforced Concrete (ACE 318-83) and the design of drilled shafts. The context of design includes...
Computer Aided Design of Reinforced Concrete
An interactive computer-aided design (CAD) program for the design of reinforced concrete members is herein described. The program, called ECPRS, designs reinforcement and performs all...
Pavement Recycling: Stopgap or Remedy?
Recycled pavements cost less than new asphalt concrete overlays, but no long term data has ratified how recycled pavements' strength and durability compare to virgin material....
RCC Dam Incorporates Innovative Hydraulic Features
An overview of the features of Monksville Dam is presented, with emphasis on the hydraulic components of the project. This 150-foot (45-meter) high roller compacted concrete structure...
Willow Creek Dam--To Be or Not To Be
In Heppner, Oregon, several alternatives for flood control were considered. A concrete gravity dam constructed using roller compaction methods was selected because of the greatly reduced...
Pipeline Materials and Design
The proper use of pipeline materials and design is obviously paramount in the private and public works sectors. The introduction and proper use of new piping materials and design procedures...
Prestressed Concrete Pavements: Status Report
Prestressed concrete is cost-competitive with and requires less maintenance than conventional concrete, but acceptance of prestressed pavements in this country has been slow. While Europe...
Superplasticizers: Reducing Water in Concrete
Superplasticizers or high-range water reducers are new types of chemical admixtures which when incorporated into concrete can cause significant increases in its slump but without any loss...
Asphalt: Great Expectations
A $50 million, five year research program has been proposed for research into asphalt as part of the larger ($150 million) Strategic Transportation Research Study (STRS). The research...
Structural Trends in New York City Buildings
This story is based on interviews with some leading structural engineers in New York City. It highlights the major structural trends in building design in that city. Case histories of...
Electronic Computation
Dramatic changes have occurred in computer-aided structural engineering during the past 25 years. Computers have evolved from large, slow processors with little available storage to fast...
Recent Developments in Pavement Skid Resistance
As pavements wear, they lose some of their skid resistance. This article discusses some of the leading options for restoring a pavement's skid resistance. The possibilities...
Superplasticized Concrete Takes Off in Dallas
Some engineers are calling superplasticized concrete the most important advance in concrete technology in over three decades. Over the past four years superplasticized concrete has begun...
Restoration
After the San Fernando earthquake of 1971, California's State Capitol Building was declared an earthquake hazard and vacated. It took the most extensive structural and architectural...
Bridge
Seven Mile Bridge is the longest, continuous precast post-tensioned segmental concrete bridge in the world. In addition to its function as a main artery connecting the Florida mainland...
Building Trends: The View from Houston
Highligts of the major changes in building design and construction over the past decade are presented from a structural engineer's viewpoint. The areas covered include: (1)...
