Bridge Rating Using Influence Surface for Curved Bridge Structures
A fairly sizeable number of curved steel bridges in Louisiana need to be rated and influence lines required to be stored. A methodology is developed and rating procedures are established....
Computer Analysis of Continuous P/C Highway Bridge Girders with Variable Depth
A computational procedure and associated computer program were developed for the analysis and design of P/C continuous beams with variable depth. Using this program, continuous girders...
Impulse Effect on Redundancy of a Tied-Arch Bridge
This paper studies the redundancy of a tied-arch bridge using a 3-dimensional finite element computer model. By using static incremental loading simulation, a tied-arch bridge designed...
Design and Implementation of a Database for Seismic Evaluation of Structures
The seismic evaluation of large structures, such as bridges, requires a comprehensive framework for managing the data. An evaluation typically involves the dynamic analysis of a number...
Discrete Modeling of Soil-Structure Interaction Under Dynamic Loading
A proposal of discrete modeling useful to describe behavior of structures burried in the ground under air explosion is presented. In the modeling emphasis is laid on determining the space...
SELECTCRANE: An Expert System for Optimum Crane Selection
Every major project undertaken today requires the services of a crane(s) to ensure that all materials and equipment hoisting and placement are performed in the most efficient manner. The...
Seismic Analysis of Reinforced Concrete Building Using Finite-element Techniques
The response of a reinforced concrete building subjected to earthquake loading has been obtained on a personal computer using the finite-element code STARDYNE. For preliminary design,...
Computer Analysis of Lateral Loading in Wood-Framed Structures
Building codes and design techniques associated with single-family housing need to incorporate advances in architecture and construction so that the traditional life-safety building codes...
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...
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...
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....
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...
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...
