Finite Element Limit Load Analysis by the Static Approach Using Nonlinear Programming
The static approach to limit analysis using finite element modelling is formulated as a nonlinear programming problem and applied to the vertical cut problem. Whereas the kinematic approach...

Rotating Crack Model and Fracture in a R/C Medium
In this study the potential of the development of cracks in the members of a reinforced concrete large panel structure is considered. The analysis is carried out using finite element modeling...

Integrating Computer Application for Pavement Management: A Case Study
This paper presents a case study of the process through which a relational database management system and stand-alone application programs are developed and integrated to form a comprehensive...

An Object Oriented Highway Information System in the Client-Server Environment
This paper discusses issues required for the development of an object-oriented (OO) highway information system in a client-server environment based on the System Object Model (SOM) in...

An Overview of the Analysis and Design Techniques Used on the Main Tunnels of the SSC
Sophisticated numerical analysis and design techniques were devised for the Supercollider in order to produce a design which closely reflected the constraints of the construction processes,...

Numerical Modeling of Initial Ground Movement in an Instrumented Superconducting Super Collider Shaft
A 5.5 m diameter shaft was sunk into a rock formation of Taylor Marl to a depth of 61 m at the Superconducting Super collider (SSC) site. Numerical modeling using finite difference analysis...

Prediction of Ground Deformations Due to Excavation-Application to Tunnel Lining Design in Weak Rock
Prediction of ground deformations due to excavations is simulated by three dimensional non-linear finite element analyses. It considers various in-situ ground stress levels, excavation...

Three Dimensional Simulation of Progressive Tunneling Process for Lining Design of Intersecting Tunnels in Soft Rock
This paper presents the results of the state-of-the-art three-dimensional nonlinear finite element modeling of progressive tunneling process and its comparison with field data. Reasonable...

Creative Design Using a Genetic Algorithm
Genetic algorithms provide a methodology for searching a space and are typically associated with optimization or classification problems. The possibility for genetic algorithms to produce...

A Version and Configuration Scheme for Collaborative Engineering
This paper presents a data management model for collaborative design. Versions are proposed to support the independent evolution of design alternatives in an individual discipline. configurations...

Database Integration in Support of Construction Management
This presentation will describe how new object-oriented technology is being applied to this problem. The goal of this use of object-oriented systems is 1) to provide a method for processing...

A Computerized Methodology for Conducting Pedestrian Gap Studies
this paper will detail recent improvements with the procedure the New York City Department of Transportation utilizes when conducting Pedestrian Gap Studies. These improvements were made...

Quick Checks for Structural Computer Analysis
When working with general structural analysis programs, there are some fast ways to check the input and output. This paper reviews some methods for verification of results of computerized...

A Real-Time Graphical Interface to a Two-Dimensional Groundwater Flow and Mass Transport Model
This paper describes the implementation of a graphical interface to the U.S. Geological Survey's Method of Characteristics (MOC) groundwater flow and mass transport model....

Facilitate Delay Claim Analysis with As-Built Schedule Databases
A computer-based As-Built Schedule Database can provide a useful tool for the investigation of project performance. The facts recorded in the database may be used to identify actual sequential...

The Use of SCADA for Real-time Calculation and Monitoring for CT Compliance at the Ralph D. Bollman Water Treatment Plant
The contra Costa Water District (CCWD) of Concord, CA was formed in 1935 under the authority of the State Water Code. CCWD purchases its water supply from the Central Valley Project (CVP),...

Contemporaneous Development of Field Data: Transportation Construction Claim Defense
This paper addresses the continuing development of a construction field database system documenting resources applied on the jobsite by Contractors. The paper focuses on the case study...

Computer Use in Claims Analysis -- Roundtable Discussion
Preparation or defense of construction claims is inherently time consuming and often counter-productive. This outline discusses some tools currently used in the construction industry to...

CadVisor (CAD Equipment Analysis and Selection System)
This paper describes a system called CadVisor (CAD Equipment Analysis and Selection System) developed by the U.S. Army Corps of Engineers Construction Engineering Research Laboratories...

Practical Approach to Cope with Construction Cost Uncertainty in an Inflationary Environment
There are actions suggested to mitigate the risk in costs caused by an inflationary economy, such as escalation clauses and including price contingencies in the bid . This paper presents...
