Experimental Study on Structural Control for Seismic Loads Using Passive and Active Devices
The feasibility of controlling the responses of structures against seismic loads is investigated through some experiments and numerical analyses for both the passive and active control...
Tradeoffs Between Active Control and Identification of Structural Systems
This paper explores the tradeoffs between structural identification and structural control in a quantitative manner. Through the intemediary concept of an optimal input, it is shown that...
Foundation Engineering Constraints in Karst Terrane
Cavity-prone carbonate rocks are found in many Appalachian valleys and represent a poorly recognized hazard. This paper reviews the nature of the problem of founding above these Cambro-Ordovician...
Location of Geologic Discontinuities by Geophysical Techniques
An overview of the seismic refraction method and resistivity methods is given. These two geophysical techniques are integrated into a systematic method for locating geologic discontinuities...
Some Dilatometer Test Results in Pennsylvania and New York
This paper starts with a brief introduction to the dilatometer and piezoblade. Test results in four different areas are presented. DMT soundings at LR 67057 (Legislative Route numbers...
Identification and Characterization of the Collapsing Alluvial Soils of the Western United States
Suggested procedures for the identification and characterization of the collapsing alluvial fan, mudflow and debris flow deposits of the arid and semi-arid parts of the western United...
Design Methodology for Foundations on Stone Columns
Stone columns offer the geotechnical engineer a valuable and viable technique for stabilizing sites underlain by soils ranging from soft clays to loose silty sands. A discussion of the...
Jet Grouting for Underpinning and Excavation Support
Jet Grouting as a new tool for underpinning and excavation support is presented, describing the systems of Jet Grouting and its advantages over conventional underpinning techniques. A...
Case Histories of Shallow Foundations on Improved Soil
Case histories for four projects, with structures varying from a 27-story high rise to a one-story shopping center, are presented. For each of these projects, improving the soil to allow...
Pile Foundation Construction Practice in Stiff Clays with Dense Granular Layers
A survey was conducted recently in conjunction with a project located in the San Francisco Bay Area to ascertain the general pile driving practice in stiff overconsolidated clays interbedded...
Cost Effective Pile Foundation Supports Fast Track Paper Mill
This paper decribes the generalized subsurface conditions, pile evaluation and load test program, pile and piling contractor selection, production pile installation, and quality assurance...
Interaction of Geology, Construction Practice and Foundation Design
The influence of geologic knowledge and construction practices on the geotechnical foundation design process has been assessed and summarized. Particular emphasis has been given to the...
Building on the Coastal Barriers Resource Act
In 1982, the Coastal Barrier Resources Act (CBRA) was enacted to minimize the loss of human life, wasteful expenditure of Federal revenues, and damage to fish and wildlife and other natural...
Erosion and Washover in Coastal Louisiana
In 1985 three hurricanes affected the barrier coastline (Caminada-Moreau Headland) of Louisiana. These produced severe coastal erosion and rapid washover extension. Using the 1979 U.S.G.S....
Environment Exploitation by Prehistorical Population of Rio De Janeiro
The specific purpose of this project was to establish the cultural contexts in the area being studied as well as to define the mechanisms of environmental manipulation that were employed...
Computer Utilization in Structural Engineering
This volume contains the papers presented at the 1989 Structures Congress sponsored by the Structural Division of the American Society of Civil Engineers that deal directly with the application...
Perceptions of Architects Regarding Use of Computers and Educational Requirements for Architectural Technicians
This paper identifies those cognitive competencies common to all CAD programs to determine which will best prepare the students for entry-level CAD proficiency and flexibility within the...
Real-Time and Off-Line Aids for Teaching Digital Control
This is a report of unique computer tools developed for teaching of the design of digital control systems at the University of Wyoming. The real-time components of the laboratory involve...
Safety in the Industrial Robot Environment
Safety requirements differ for applications with or without a human interface. The extent of human interface with the robot must be determined. Design of the robot, guarding, access, and...
ROBOSIM: A Simulation Package for Robots
ROBOSIM was developed first in a VAX environment. Using PC's with a terminal program capable of emulating a TEKTRONIX 4014, students can create robots, see them graphically,...
