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...

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...

Load-Permit Truck Operations in New York State
This paper presents the results of a survey of indivisible-load permit vehicle operations in New York State. The survey was conducted in the context of an investigation into the impacts...

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...

A Method of Computing Impact and Fatigue Life in the Railway Steel Girder Bridge
The purpose of this paper is to investigate the dynamic interactions between an steel girder bridge and a moving freight train. A non-linear, 100-ton, freight car vehicle model and a 70-ft...

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)....

Retrofitting Aerodynamic Performance of Bridges
This paper is a review of aerodynamic retrofit techniques for long-span bridges. The discussion includes a description of the aerodynamic problems of static divergence, flutter, buffeting,...

Dynamic Response of a Building with Dual System
The paper presents the dynamic response of a 30-story building with dual system consisting of cross-bracing and beam-column moment resisting frames. Two types of beam-column connections,...
