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)....

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...

N-Pad?A Three-Dimensional Program for the Analysis of Base-Isolated Structures
N-PAD is a three-dimensional computer program especially written for the analysis of base-isolated structures. The program is designed with the ability to model various types of isolation...

System Identification of Meloland Road Overcrossing
The Meloland Road Overcrossing (MRO) is a two-span reinforced concrete bridge structure located east of El Centro, California, 0.3 mi from the Imperial Fault. The Imperial Valley Earthquake...

System Identification of a Large Structure Using Pseudo-Dynamic Test Data
This paper deals with structural modeling and the determination of optimal nonlinear models by applying system identification techniques to inelastic pseudo-dynamic test data from a full-scale,...

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...

Hydrodynamic Isolation of Concrete Dams
The feasibility of reducing hydrodynamic effects in the earthquake response of concrete dams by anchoring gas-filled balloons or injecting bubbles in the water is investigated. Significant...

Seismic Isolation of Storage Tanks
There has been a significant amount of research activity over the past decade on the seismic design of storage tanks. The seismic design issues and limit states are quite complex due to...

Biaxial Damage Assessment
The structural system under investigation is a frame subject to seismic excitations. The analysis accounts for the spatial distribution of beams, columns and bracing system. It also considers...

Seismic Isolation of the USC University Hospital
This paper provides an overview of the various structural engineering tasks that are associated with the implementation of the design of a seismically isolated structure. The project is...

Seismic Isolation for the Los Angeles County Fire Command and Control Facility
The use of seismic isolation is becoming an increasingly important consideration in improving the earthquake lifelines of a community. This paper identifies the major problems encountered...
