Advances in CAD for Structural Engineers
In the 1980's Computer-Aided Design (CAD) will offer the structural engineer an opportunity to improve his work. Decreases in the cost of equipment and improvements in computer-aided...
Relational Model for Computer Analysis and Design
One of the most critical elements in engineering analysis and design is data management. Relational database systems have been proven to be an excellent tool for managing the voluminous...
Advanced Graphical CAD System for 3D Steel Frames
An innovative, advanced graphical computer-aided design system, called STEEL-3D, is described. The main objective of this program is to provide the engineer with all the tools necessary...
Automated Analysis Model Generation
The state of development of the capabilities needed to automatically link the geometric definition of a CAD system to finite element analysis is discussed. Areas considered include fully...
Engineer-Constructor Experience with Computer Aided Design and Engineering
Stone & Webster Engineering Corporation has used CAD/CAE equipment since 1974 and has developed organizations and procedures for integrating the technology into the design process....
Computer Aided Design of Reinforced Concrete
An interactive computer-aided design (CAD) program for the design of reinforced concrete members is herein described. The program, called ECPRS, designs reinforcement and performs all...
Influence of Connection Behavior on Steel Frame Designs at Factored Loads
This paper illustrates how interactive computer graphics, when interfaced with nonlinear inelastic frame analysis programs, can provide a powerful tool for design of semi-rigid frames...
Consulting Engineers' Experience with CAD
A general, brief history of the role of computers in design in consulting engineering practice is presented. Their changing role from their initial early use to today's involvement...
Numerical Analysis of Two Embankment Foundations
Two case histories of the performance of a compressible embankment foundation are analyzed using the Cam-Clay constitutive model and a finite element consolidation program. The I-95 highway...
Consolidation-Strength Analysis for Soft Soils
A one-dimensional consolidation analysis including prediction of consequent shear strength increase for soft soils which exhibit large secondary compression is proposed. Consolidation...
Selfweight Consolidation of Very Soft Clay by Centrifuge
This paper reports a series of selfweight consolidation tests and their analysis by Mikasa's consolidation theory. The tests covered a coastal reclamation project and the...
The Use of Soil Mechanics Capabilities in a General Purpose Finite Element Program
This paper describes capabilities, points out features of implementation in a general purpose code, and describes some numerical considerations. The paper makes use of illustrative solutions....
Validation of Consolidation Properties of Phosphatic Clay at Very High Void Ratios
The void ratio-effective stress and void ratio permeability relationships for phosphate slime mine tailings were measured by several methods. The measurements were used in nonlinear finite...
Consolidation of Multi-layered Clay
Three kinds of clay with different plasticity were pre-consolidated from slurry and combined into typical two layered systems consolidated under 40 tf/m**2 with single drainage condition....
Yield Behaviour and Consolidation. I: Pore Pressure Response
This paper discusses the frequency of occurrence of anomalous consolidation behaviour. The behaviour of soft clay is discussed briefly in terms of the effective stress path/yield envelope...
Yield Behaviour and Consolidation. II: Strength Gain
In Part I it was shown that in situ yielding of soft foundation clays significantly affected consolidation behaviour and that yield could be defined using the effective stress path/yield...
Consolidation of Permafrost upon Thawing
Methods of predicting initial consolidation upon thawing and the subsequent consolidation with time under increasing pressures are presented in terms of changes in unit weight. Procedures...
Trends in Computerization in the Eighties
This paper addresses trends in computer-aided productivity tools for Civil Engineers in the eighties. Certain aspects of the past history, present status, and future of CAD/CAM and CAE...
Monitoring of an Ocean Dredged Material Disposal Site
The Tampa Harbor Project involves deepening and widening approximately 50 miles of existing shipping channel in Tampa Bay, Florida, with the removal of approximately 70 million cubic yards...
REMOTS Sediment Profiling at the Field Verification Program
Disposal of uncapped highly polluted Black Rock Harbor muds took place in April-May 1983 at a buoy located within the Central Long Island Sound Disposal Area in 62-66 feet of water. Baseline...
