Computer-Aided Structural Analysis
Finite Element Methods and other numerical techniques are often taught nowadays in the undergraduate Structural Analysis courses. Commercial, structural computer programs are becoming...

Accurate Response Analysis of Seismic Distributed Mass Systems
A dynamic analysis technique of distributed mass structures is presented with a combination of the dynamic load factor approach and the dynamic stiffness matrix method. The dynamic stiffness...

COMBAT.PC; a New Windows-Based Tool for Three-Dimensional Dynamic Analysis of Multi-storied Building Structures
By some accounts, analytical capability without the power of visualization is little productive; visualization is the tool that will turn computational power into practical results. COMBAT.PC...

A Survey of Discrete Variable Optimization for Structural Design
Available methods for discrete variable structural optimization are reviewed. Methods are classified according to three categories: branch and bound, approximations using branch and bound,...

Discrete Optimal Design of 3D Frameworks
The paper describes a discrete optimization method for the least-weight design of three-dimensional (3D) steel building frameworks. The method involves the coordinated application of structural...

Optimal Design of Reinforced Concrete Structures via Decomposition and a Variety of Search Strategies
This paper presents a strategy where the design of a reinforced concrete structure is not only automated, but optimized. The strategy employs decomposition to subdivide the problem into...

Simultaneous Design and Location of Actuators
A chance constrained model for determining optimal dynamic control parameters for structures subjected to probabilistic forcing amplitudes is presented. Optimal feedback control parameters...

Structural Optimization to Limit Natural Periods
It is necessary to limit the natural periods of some structures to control their response to dynamic loads. Floor systems with natural periods greater than approximately 0.15 seconds may...

Stiffness Optimization Methods for Lateral Systems of Buildings: A Theoretical Basis
The sizing of the members of the lateral resistance system for multi-story buildings is often controlled by stiffness requirements. In order to achieve economical buildings, it is important...

An Analysis Procedure for Cable Structures Using an Isoparametric Finite Element
The computer modeling and analysis of cable structures creates a major problem for the analyst in that the geometry of the cables is dependent on analysis results. The purpose of this...

Computer Modelling of Concrete Cover Effect on the Behavior of Fiber Concrete Subjected to Monotonic Pullout
The objective of this paper is to evaluate the concrete cover effect on the bond behavior of bars embedded in normal and fiber reinforced concrete. Nonlinear finite element analysis is...

Data Modelling for Steel Frame Structures
The first step to automate any facet of structural engineering is developing a suitable data representation upon which the computer program will operate. However, there is no standard...

What Object-Oriented Programming Can Mean for Structural Engineers
In recent years, object-oriented programming has become an important topic in the computational community. Although generally viewed as a programmers' tool, object-oriented...

GIS in Transportation Modeling: Merging MINUTP with GIS
Transportation system modeling involves a great deal of information on features which are geographically distributed over a study area. Geographic Information Systems (GIS) are suited...

GIS Applications Floodplain Reconnaissance Studies
U.S. Army Engineer District, New Orleans (NOD) employed a Geographic Information System (GIS) to support a flood plain management Reconnaissance Study. The study region encompassed the...

Extending GIS Capabilities for Enhanced Sewer System Modeling
A limitation of many sewer system modeling programs is their inability to accept and display graphic data. By the same token, many GIS packages, which handle graphics, aren't...

A GIS Approach to Urban Water System Planning
Procedures for projecting future water needs have ignored the spatial distribution of consumers. However, with a GIS approach to water demand forecasting and supply planning the spatial...

Integrating GIS and Civil Design
Genasys Inc. has traditionally specialized in Geographic Information Systems (GIS) and Computer Mapping. The Genamap product is the world leader in UNIX based GIS. Over the last five years...

A Geographic Information System to Support State-Wide Hydrologic Modeling with the SCS-TR-20
A geographic information system (GIS) that is structured for hydrologic analyses has been installed in the Maryland State Highway Administration's (MSHA) Division of Bridge...

Runoff Modeling Using the Geomorphological Instantaneous Unit Hydrograph and ARC/INFO Geographic Information System
The degree to which the spatial variability of watershed characteristics (geographical and climatological) is recognized for simulating watershed runoff depends on the hydrologic model...
