Bridge Condition Rating Using Fuzzy Sets and an Eigenvector of Priority Settings
A simplified methodology for combining the condition rating of the various elements of bridge components (deck, superstructure or substructure) is developed using a multi-attributive decision...

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...

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...

A Knowledge-Based Computer System for Financial Wind Risk Management
This paper presents the results of a sponsored applied research project conducted by a multi-disciplinary team to integrate state-of-the-art methods in wind and collateral (e.g., surge,...

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...

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...

Footing Load Tests on Sand
Four full size footings were load tested at a site in Texas. The embedded footings were situated on a thin layer of stiff clay underlain by a thick deposit of medium dense to dense sand....

Settlement of Shallow Foundations on Sand
A new method for estimating the settlement of shallow foundations on sand is presented. The method is based on elastic stress-strain theory and is designed for use with soil data from...

Uplift Load-Displacement Behavior of Grillage Foundations
Full-scale field tests were conducted on steel grillage foundations for lattice transmission line towers that had been in place since 1929, 1947, and 1958. A total of eight tests were...

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...

Deformations in Sand Layer During Pile Driving
This paper presents measurements of settlement and lateral soil movements in a medium dense to dense sand layer due to densification during driving of precast concrete piles. At one end...

Pile Settlement Based on Dynamic Measurements
Dynamic measurements during driving are well established for monitoring driving performance and the prediction of pile capacity. Post driving, signal matching office methods (e.g. CAPWAP)...

Testing and Predicting the Movement of a Drilled Shaft in New Mexico
The New Mexico State Highway and Transportation Department (NMSH&TD) have been using drilled shafts for supporting bridges in the State of New Mexico. Several drilled shafts were...

Static Pile Load-Movement From Dynamic Measurements
Static loading tests have traditionally been performed to determine the characteristics of pile load-movement relationships. Due to the expense involved and time required, this type of...

Design and Performance of a Piled Raft Foundation
The foundation system for a recently constructed building in Perth, Western Australia, consisted of combined pile groups and raft elements, with a total of 280 bored piles incorporated...

Model Tests on Caissons
Laboratory tests were conducted on model caissons to better understand the settlement/deflection behavior of open ended caissons on sandy soil, with embedment depth, caisson diameter,...

Wanapum Dam Embankment Settlement Study
This paper discusses the long term vertical movements of a zoned earth embankment. Vertical movement of the Wanapum Dam embankment has been monitored since its completion in 1964. The...

Settlement Evaluation for Cap Closure Performance
Predicting short and long-term performance of a landfill cap system is a difficult task considering the generally unknown nature of the waste and magnitude and variation of settlement...
