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 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...

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...

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...

Use and Abuse of Settlement Analysis
Terzaghi's concept of settlement analysis included comparison of prediction with reality and investigation of the causes of the differences. Present usage is often limited to prediction....

Settlement of Embankments on Soft Clays
It is now possible to make reliable predictions of settlement of embankments on soft clays. In most situations, where the embankment is designed to resist undrained instability during...

Settlement of Tanks on Clay
Steel tanks for storage of water, oil, and other liquids are capable of withstanding large, but not unlimited, settlements without damage. In most cases shallow foundations provide adequate...

Mat Foundation Design: An Historical Perspective
Nearly a half century ago, Karl Terzaghi rationalized the analysis and design of mat foundations with the conclusion that subgrade reaction was the most important variable. Soon after...

53 WAK Tests on Spread Footings
Research on the prediction of soil stiffnesses of spread footing-soil systems using Wave Activated Stiffness (K) or WAK tests was conducted. As discrete lumped-parameter model with a mass,...

Vertical and Horizontal Deformations for Foundations on Sand: An Experimental Study
A natural scale model is used in order to investigate experimentally the sand soil deformation behavior which accepts loads by shallow foundations. The vertical and horizontal soil displacements...

Settlement Behavior of an Avalanche Protection Gallery Founded on Loose Sandy Silt
An avalanche protection gallery located in the Swiss Alps was founded on alluvial ground close to the steep rocky mountainside. The rear retaining wall, at a variable distance of a few...

Displacement of Landmark Building Resulting from Adjacent Construction Activities
This paper describes the observations and presents comments related to the measurement of settlement and the avoidance of damage to a historic structure in the City of New York from adjacent...

Horizontal and Vertical Movements of Bridge Piers Subjected to Ship Impact
Results of a detailed analysis to evaluate the potential horizontal and vertical movements of the piers of George P. Coleman Bridge, Virginia, in the event of ship impact are presented...
