Floating Membrane Supertankers: Are They Feasible?
Optimal shapes of long cylindrical membrane containers are obtained by restricting the circumferential membrane stress to be tensile and constant throughout the tanker. Optimality is achieved...
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...
Fatigue Strength of Corroded Rolled Beams
Highway and railway bridges fabricated from ASTM A7, A36, and A572 steels will corrode if the paint system is allowed to fail for lack of maintenance. Corroding members lose cross section...
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...
Fatigue Evaluation of a Riveted Railroad Bridge
An 83 year old railroad bridge was analyzed for fatigue based on historical records such as the original schedules. Based on the number of cycles to date, corresponding to an effective...
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)....
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,...
Status of Structural Engineering Research
Problems and opportunities for structural engineering research are being addressed in a study by the ASCE Structural Division Task Committee on Structural Engineering Research Needs/Funding....
An Education in Tunneling
In this follow-up to the author's article in the April 1989 issue of Civil Engineering, this senior civil engineer and winner of the 1988 Martin Kapp Foundation Engineering...
Hydrogeology Comes to the Surface
Before concluding whether groundwater is safe or contaminated, engineers must understand the science of hydrogeology. If they don't understand hydrogeology, unnecessary and...
Forced Vibration of Sliding Base Structural Systems
An analytical and experimental study of the effect of a horizontal sliding plane on the dynamic response of a single-story structure subjected to harmonic motion is presented. There is...
Friction-Dampers for Economic Seismic Design
A novel structural system, which combines the strength and stiffness of a braced frame and energy dissipation capacity of the friction-dampers, has been used in the design of a reinforced...
