Building Motion in Wind
The trend towards higher structural efficiency and hence lower cost has resulted in a generation of lighter and more flexible buildings with a lower inherent capacity for energy dissipation...
Asphalt Pavement Modifiers
Modifiers or additives to asphalt concrete pavements are being researched or marketed by many major chemical firms. Modifiers or additives are used to stiffen the asphalt in hot weather...
Highway Quality Level Program
This article describes three versions of BASIC programs for microcomputers, prepared for the Federal Highway Administration, to calculate a statistical measure of highway quality. Using...
Superminis for Super CAD
Many second time users of computer-aided design software and hardware, in their efforts to have more power and flexibility, are switching to superminicomputers and building their own systems....
CAD Goes into Analysis
In the past, computer analysis of a design was always a separate and distinct step from CAD. Now, an increasing number of systems are combining the two. One system, SSCAD, allows the engineer...
CAD Mapping Trailblazer
Until three years ago, few civil/surveying firms had automated both surveying (including digital recording of angles and distances shot in the field) and the related design and drafting....
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...
Use of SPT and CPT Tests for Evaluating the Liquefaction Resistance of Sands
A cone penetration test (CPT)-liquefaction resistance relationship has been established using the large body of standard penetration test (SPT) data. Factors for relating CPT tip resistance...
Pressuremeter Tests and Shoring Wall Design
Pressuremeter testing was used as an integral part in the design of the temporary tieback shoring wall for the Columbia Center office building in Seattle, Washington. Pressuremeter testing...
Laboratory and Field Evaluation of Cone Penetrometers
Cone penetrometers from 8 organizations have been studied by performing laboratory tests and field tests. The testing show that pore pressure and temperature zero shift affect significantly...
In-Situ Testing to Characterize Electric Transmission Line Routes
A review of the literature has shown few definitive studies which separate test variability from soil inhomogeneity. A sensitivity study was performed to evaluate the effects of the overall...
Effect of Cementation on the Cone Penetration Resistance of Sand
A laboratory study was conducted to investigate the effect of cementation on the cone penetration resistance of sand. A new apparatus to form homogeneous artificially cemented sand specimens...
Design Parameters for Grouted Piles in Rock From In-Situ Load Tests
A series of pile load tests were performed at an onshore site to develop final geotechnical parameters for the Gaviota platform foundation which consists of large diameter drilled and...
The Pressuremeter for Foundations: French Experience
The paper presents historical information on the development of the pressuremeter and its application in the Laboratories Central des Ponts el Chaussees (LCPC). The continuous research...
Ports '86
Ports '86 had the theme of Innovations in Port Engineering and Development with keynote speakers looking ahead to Port Development in the 1990's. The program...
Designing for Maintainability
Inspection and maintenance guidelines are unavailable for many buildings. Building owners seldom have the benefit of such information because buildings are often considered passive systems,...
Parking Lot Gets White Top
The many-acre parking lot at the Valley Fair Mall shopping center in Salt Lake City, Utah is described. In 1985 the asphalt pavement was overlaid with concrete, making it one of the relatively...
Beauty and the Bridge
At the California Department of Transportation, a special aesthetics unit works closely with the design engineers in the Division of Structures, which has won almost 400 prizes for its...
Effect of Particle Size on Sludge Dewaterability
Using a modified Buchner funnel apparatus to measure specific resistance and a sequential centrifugation/filtration procedure to fractionate a sludge, it was possible to more precisely...
Sea Level Rise and Coastal Stormwater Drainage
Global sea level rise as a result of the greenhouse effect and the past trend and future projection on the rise are discussed. Potential problems associated with coastal stormwater drainage...
