Modeling Human Error in Structural Design and Construction
Human error is recognized as the major cause of structural failure. Moreover, it may greatly exacerbate the damaging effect of other hazards, such as earthquakes. The objectives of this...
Finite Element Analysis of Reinforced Concrete Structures
The 40 papers included in this publication were presented at the Joint U.S.-Japan Seminar on Finite Element Analysis of Reinforced Concrete. Two state of the art reviews discuss the role...
Performance Analyses and Design for Urban Bus Transit
This paper describes a Management approach to Bus Transit Systems based on the treatment of Demand, Supply and Policy. The procedure described is currently supported by a series of interactive...
Performance Evaluation and Optimization of Transit Operation
This paper discusses the use of a Performance Evaluation Model in evaluating the effect of short term policy changes including fares, service frequencies, route coverage, and route alignment....
An Infrastructure-Based Strategy for Guiding Reconstruction, Development and Reconciliation in Lebanon
In 1979 an agreement was entered into between the CDR, U. S. A. I. D. , and the American University of Beirut (AUB) whereby an interdisciplinary team of AUB researchers would develop a...
Influence of Artificial Island Side-Slopes on Ice Ride-Up and Pile-Up
An artificial island slope protection scheme must be able to inhibit ice ride-up and pile-up in order to minimize operational interruptions. The prediction of ice ride-up and pile-up mechanisms...
Probabilistic Description of Ice Forces on an Offshore Arctic Structure
A probabilistic simulation model has been developed to describe the frequency and outcome of multi-year ice floe encounters with a fixed offshore structure located in the Beaufort Sea,...
Selection of Environmental Design Criteria for Arctic Structures
Where data are insufficient for calculation of extremes using probability theory, design criteria may be reasonable defined by combining available data, knowledge of physical processes...
Centrifugal Modeling of Ice Forces on Single Piles
The ice forces and ice floe failure mechanisms associated with an ice sheet surrounding a vertical cylindrical pile were evaluated. A test system was developed to model ice forces in gravity...
Endochronic Constitutive Modeling of Frozen Soil
The static behavior of a permafrost type foundation, for a typical artificial island in the Arctic, is determined using endochronic axisymmetric finite element analysis. Endochronic constants...
Geotechnical Thermal Analysis with a Microcomputer
A computer program entitled TDHC (Two-Dimensional Heat Conduction), based on finite element modelling, is capable of solving two-dimensional nonsteady-state heat conduction problems. These...
Comparison of Wave Overtopping Prediction to Measurements from Large-Scale Model Tests
A recent large-scale physical model study was sponsored by Arco Alaska, Inc. , to evaluate slope designs for an Arctic offshore oil drilling island. The drilling island will be located...
Validation of the CICE Code for Ice Ride-Up and Ice Ridge Cone Interaction
The discrete element method is capable of analyzing multiple, interacting, deformable, discontinuous or fractured bodies undergoing large motions and rotations. The formulation solves...
Earth Pressure on Underground Rigid Pipe in a Centrifuge
A series of centrifugal model tests on underground pipes that simulate the actual construction process were carried out to investigate the earth pressure concentration onto the pipe (particularly...
MILHY?A Microcomputer Based Hydrologic and Hydraulic Model
MILHY is an interactive, single event, lumped parameter model used to estimate streamflows and water surface profiles. The model was designed for use on basins less than approximately...
Initial Operation Model for the Central Arizona Project
A microcomputer program for operating uncompleted portions of the Central Arizona Project has been developed. Engineers may use this program daily to assist in scheduling pumping plant...
Local Pressure in Ice-Structure Interactions
Two models for the determination of local pressures during marine ice or iceberg collisions with bottom-founded structures are presented. The first model is a two-dimensional analytical...
Random Vibration Techniques
The paper presents a review of random vibration techniques for analyzing dynamic systems from the perspective of applicability to structural engineering. Problems involving linear or nonlinear,...
Design Load Combination Factors
This paper reviews alternative load combination formats for ultimate limit states in codified structural design. The need for explicit consideration of load-time variations and random...
Watershed Management in 1985
Today's technology in subalpine watershed management is based on carefully designed watershed experiments beginning with Wagon Wheel Gap in 1909. Subsequent advances in process...
