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 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...
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...
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...
Compressibility of Clays: Fundamental and Practical Aspects
The compressibility of natural clays is influenced by strain rate, temperature, sampling disturbance, stress path and some restructuration factors. The first part of the paper reviews...
Methods to Reduce the Settlement of Embankments on Soft Clay: A Review
New trends have been observed during the past ten years in the practice of settlement control for embankments on soft clays: they include increased use of rigid (piles) or semi-rigid (stone...
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...
Effects of SPT Equipment and Procedures on the Design of Shallow Foundations on Sand
The effect on our computations of bearing capacity and settlement of shallow foundations suggests that as more efficient SPT hammers and procedures are used, our shallow foundation designs...
Predicting Shallow Foundation Settlement in Sands from DMT
The dilatometer test is ideal for predicting the settlement of shallow foundations. It directly measures a modulus of the soil and has been correlated to predict stress history. Recently,...
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,...
WAK and Full-Scale Load Tests on Granular Fill
For footings on granular fill that includes cobble- and boulder-size materials, in situ tests cannot be used to estimate foundation settlement because such fill is difficult to explore...
