Cold Regions Hydrology and Hydraulics
The Cold Regions Hydrology and Hydraulics Monograph is the eighth in a series of monographs prepared by the ASCE Technical Council on Cold Regions Engineering. The book is intended to...
Geosynthetic Shields For Dams
A series of large dams in Europe, waterproofed by geosynthetics, may become U.S. prototypes. In Europe, the faces of more than 30 large dams now contain geotextiles and geomembranes. In...
Building in Reservoirs
The Croton Supply System, one of the three major water supply systems for New York City, is undergoing extensive rehabilitation. In an innovative use of space, some of the new construction...
Diatomaceous Soils: A New Approach
Diatomaceous soils are formed over long periods of time when the skeletal remains of plankton and other single-celled marine creatures sink and accumulate in lakes, estuaries and oceans....
Commuter Control
Traffic management systems are a relatively new way to expand the capacity of existing highways and to utilize new ones realistically. Several major systems have been in place and new...
Haunches and Hangers
The $210 million VA Medical Center at Houston features a structural system as innovative for the 1990s as the interstitial space concept was in the 1960s. The medical center, designed...
An Education in Tunneling
A senior civil engineer and winner of the 1988 Martin Kapp Foundation Engineering Award describes the evolution of U.S. tunneling technology and practice. Trained as a structural engineer,...
Representation of Strategic Choices in Structural Modeling
A major concern in structural modeling is the proper choice of tools to achieve stated objectives. Problem statements in structural analysis and design are usually made in fairly abstract...
Experiments on Active Structural Control Under Seismic Loads
Two control systems, an active tendon system and an active mass damper system are selected for study for possible real structural implementation. Presented in this paper are simulation...
Frequency Response Design of Controlled Structures
The installation of optimal control systems has been shown to be effective in reducing the vibration responses of structures. In addition to the effectiveness, there are many factors that...
A KBES for Seismic Design of Buildings
A knowledge-based expert system for earthquake resistant design of buildings is described. The knowledge-intensive nature of the domain and the consequent motivation for an expert-system...
A Prototype Expert System for Steel Connections
A PC-based, menu-driven, five-module prototype knowledge-based system has been developed for steel connections. The system can solve various steel connection problems by utilizing the...
Computers in Civil Engineering Education at Clemson University
This paper describes the current use of computers in the civil engineering undergraduate education of students at Clemson Univrsity, the land-grant university of the State of South Carolina....
An Integrated Knowledge System of Seismic Vulnerability and Risk for Engineered Facilities
This paper describes an integrated knowledge system for the assessment of the seismic vulnerability and risk of engineered facilities. The system integrates knowledge from many fields...
A Knowledge-Based System for Evaluating the Seismic Resistance of Existing Buildings
The large number of existing buildings designed without considerations of seismic loading warrants the development of computer aids for the evaluation of their seismic resistance. Since...
Vector Optimization of Structural Systems
In this paper the basic ideas of vector optimization are presented, and both the weighting and constraint methods are applied to vector optimization of truss systems by minimizing the...
Water Transport in Limestone by X-Ray CAT Scanning
The transport of water through the interior of Salem limestone test briquettes can be dynamically monitored by computer aided tomography (commonly called CAT scanning in medical diagnostics)....
Enhancing Concrete Durability by Treatment with Sealers
This paper summarizes some of the research which has been undertaken on sealers for hardened concrete during the last ten years at Wiss, Janney, Elstner Associates. Inc. The research used...
Lessons Learned in Laboratory and Field Evaluation of Accelerated Strength Tests for Quality Control of Concrete Pavements
This paper describes the results of an accelerated strength testing program performed to evaluate flexural strength potential at 28- and 90-days. Based upon a literature review of previous...
Containment Model ? Test Program and Results
Sandia National Laboratories (Sandia) completed the testing of a 1:6-scale containment building for a Light Water Reactor (LWR) in July 1987. The containment building was made of reinforced...
