Shallow Seismic Exploration in Soil Dynamics
Methods of shallow seismic exploration of soils are continually developing and evolving. Advances in techniques and equipment for performing crosshole and downhole tests, new data on interpretation...

Advances in the Art of Testing Soils Under Cyclic Conditions
The session on Advances in the Art of Testing Soils under Cyclic Loading Conditions was organized by the Soil Dynamics committee of the American Society of Civil Engineers in an endeavor...

Richart Commemorative Lectures
The geotechnical specialty known as soil dynamics has developed during the past 25 years from a minor role to a mainstream discipline. Professor F. E. Richart has played a major role in...

Geotechnical Innovations: Why Seldom Used in Highways?
Ground improvement methods introduced within the past decade to American geotechnical engineers offer cost savings, ease of construction and reduced construction time. Amont these innovations...

Probabilistic Seismic Analysis of a Nuclear Power Plant Steel Containment
Concern for the safety of nuclear power plants has motivated efforts to determine the statistical characteristics of the seismic resistance of steel containments under various types of...

Preliminary Analysis of Large Penetration Enclosures for Containment Vessels Subject to Beyond Design Basis Loadings
Numerical simulations of the macro-deformations of the sealing surfaces (gasketed junctures) of a PWR steel containment vessel's equipment hatch subjected to accident loadings...

Stress Distribution Around the Equipment Hatch Opening of a Prestressed Concrete Containment for a PWR Power Station
Results are reported of a finite element stress analysis for the linear elastic deformation around the equipment hatch opening in prestressed concrete containment. The dimensions and form...

Determination of Containment Vessel Ultimate Capacity Using Nonlinear Finite Element Analysis
Analysis of steel containment vessels is normally performed using linear elastic solutions with allowable stresses specified by applicable design codes. This method gives little indication...

ACI 349 Embedments: Code Provisions and Methods of Analysis
Steel embedments form the critical link between steel and concrete structures. Appendix B of ACT 349, Code Requirements for Nuclear Safety Related Concrete Structures, specifies the ultimate...

A New Approach to the Design of Core Support Structures for Large LMFBR Plants
The paper describes an innovative design concept for a LMFBR Core Support Structure. A hanging Core Support Structure is described and analyzed. The design offers inherent safety features,...

An Estimate and Evaluation of Design Error Effects on Nuclear Power Plant Design Adequacy
An estimate by the author is found of typical error levels contained in Structural-Mechanical-Civil Design and Stress Reports. Based on the original analysis performed to demonstrate design...

Design Criteria for Buried Flexible Pipe
A modified CANDE program was used to analyze a full factorial set of design parameters for buried, large diameter high density polyethylene profile-wall pipe. A new pipe subroutine was...

Limit State Analysis of Lattice Steel Transmission Towers
The background and present status for limit state analysis of lattice steel towers at the Bonneville Power Administration is presented. Conceptual development, a computer program, and...

Plastic Design Requirements of the AISC Proposed LRFD Specification
The American Institute of Steel Construction proposed LRFD Specification (1) has recently completed a one year period of trial use and review. This paper discusses the background of the...

Finite-Strain Axial Analysis of Piles in Clay
In the late 1970's, a series of research projects developed simple effective-stress methods to predict the axial capacity of piles in normally-consolidated clay. The method...

Centrifugal Modeling of Pile Foundations
Modeling of pile foundations in a centrifuge, where the self weight induced stresses in the soil are simulated by elevated gravity loading, is described. Hollow pipe piles in a stiff clay...

Prediction of Settlement of Single Piles in Clay
Analyses by trial were used to fit theoretical load-settlement curves to measured curves for driven piles. For the elastic method, analyses of load tests indicated that designers should...

Vertical Behavior of Two 16-Year Old Drilled Shafts
Vertical load tests were performed on drilled shafts subject to lateral confining and heaving pressures from expansive soil over 16 years. Results indicated mobilized skin friction equal...

A Flat-Dilatometer Study of Lateral Soil Response
The effect of flat dilatometer penetration on the lateral stress conditions in soil around the dilatometer blade and the soil response against dilatometer diaphragm deflection were investigated...

The Simple-Pile Approach to Pile Installation in Clays
This article describes the fundamentals of the approach and presents solutions for the effects of quasi-static deep undrained penetration of a simple solid pile on the deformations and...
