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...
Optimal Location of Active Controllers Subjected to Seismic Excitation
In the application of structural control to seismic structures certain locations are advantageous for placement of the actuators. These locations reduce the structure's response...
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...

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...
Optimization of Structures Subjected to Vibrations
A minimum cost optimization procedure is presented for the analysis of multi-degree freedom structures subjected to steady, transient and random vibration environment. The procedure is...
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)....
Concrete Strength-Quality Assurance
The usual criterion for establishing grades of structural concrete is the compressive strength measured in an arbitrary manner on a standardized specimen stored in a stipulated fashion...
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....
Vibration Control Damper Using Sloshing of Water
The objective of this study is to develop a method of reducing wind-induced vibration of long-period structures utilizing sloshing of water in tanks added to the upper part of the structures....
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...
Experimental Study on Structural Control for Seismic Loads Using Passive and Active Devices
