Computational Mechanics: Constitutive Modeling and Performance Analysis
The availability of supercomputers in the 80's has brought about a revolution in the analysis and design of complex structures. Parallel with this, computers have played a...
Stochastic Seismic Response of Simple Structures
Since, at present, it is impossible to eliminate the various sources of uncertainty related to earthquake loading, it is necessary to better understand their effects on structural seismic...
Comparative Time Domain Analysis of Some Available Analytical and Empirical Expressions for the Spatial Variability of Seismic Ground Motions
Simulations in space and time based on models for the spatial variability of seismic ground motions are generated. Displacement time histories are simulated through the spectral representation...
On the Solution of Plates and Shells Mixed Boundary Problems
Strain-stress state analysis on plates and shells under mixed boundary conditions is of significant practical value: a lot of problems, arisen in machine design, civil engineering etc.,...
Synthesis of Lateral Structural Bracing with Active Tendons
The idea of combining X bracing, viscoelastic dampers, and active tendons in a structure which has been optimized for gravity loads is presented. It is shown that reduction of the structure's...
Sensitivity Analysis of Connection Stiffness in Orthogonal Frames with End-Plate Connections
According to AISC-LRFD specification (1986), two types of construction for steel frame structure can be assumed which are Type PR (partially restrained) and FR (fully restrained) constructions....
Cables Not in Trouble
Cable-stayed bridges in the U.S. are not, contrary to reports widely disseminated in the press several years ago, about to fail from corrosion. The design, in which primary cables support...
The Pressuremeter: Some Special Applications
The preboring pressuremeter has been used for foundation design for many years. Some recent developments are presented which extend the applications of the pressuremeter. These developments...
Geotechnical Database Management Systems for Boston's Central Artery/Harbor Tunnel Project
This paper presents a geotechnical computer application currently in use on Boston's Central Artery/Harbor Tunnel (CA/T) Project. The application is designed to manage subsurface...
A Hybrid Expert System for Design with Geosynthetics
A prototype hybrid expert system is presented that selects geosynthetic materials and performs detailed designs for different geotechnical applications. An expert system is used to give...
Expert System for Driven Pile Selection
Selection of driven piles for deep foundations is a complex process. Many subjective factors enter into the decision of which pile to select, making experience an important factor in proper...
Knowledge-Assisted Interactive Probabilistic Site Characterization
This paper describes a prototype knowledge-based expert system for probabilistic geological anomaly characterization and geotechnical system reliability evaluation. The system assists...
Geotextile Edge Drain Design and Specification by Expert System
Expert systems can be developed and operated on personal computers to aid in the design of the geotextile filter component of pavement edge drains. The expanding use of geotextiles in...
An Expert System for Preliminary Ground Improvement Selection
Ground Improvement is an area which has rapidly advanced in the past two decades. Most of the work has resulted from experience in field work. Thus experience has played a vital role in...
KBES Applications to the Selection and Design of Retaining Structures
Knowledge-based expert systems (KBES) are computer programs, based on artificial intelligence (AI) techniques, designed to reach the level of performance of a human expert in some specialized...
An Expert System for Civil Engineering Applications
Civil engineering is a field where experimental knowledge has no substitute. Making experts' knowledge explicit and documenting and transferring it can have a great impact...
Do Simplistic Methods of Foundation Design Produce Reliable Foundations?
Many foundations today are designed using deterministic (single value) analysis techniques which do not reflect the natural variability of soil properties. If the standard deviation and...
Development of the South Carolina Coast 1959-1989: Prelude to a Disaster
The history of hurricanes on the South Carolina Coast is reviewed. It is shown that reasonable design wind and surge conditions could have been established before the rapid development...
Within the North Wall of Hugo (Personal Recollections of Being in the Wrong Place at the Wrong Time)
Our house is in Romain Retreat, a subdivision of lots of 1 1/2 -3 acres in Awendaw, S.C. approximately 20 miles northeast of Charleston off Route 17 and about the same distance from McClellanville...
Hugo 1989 - The Performance of Structures in the Wind
The performance of buildings in the Carolinas during Hurricane Hugo, 21-22 September 1989, is reviewed. Wind speeds in most locations were below the design levels specified in the local...
