Reliability-Based LRFD for Transmission Structures
A simple reliability-based Load and Resistance Factor Design (LRFD) method is proposed for the structural design of electric transmission lines. With the proposed method, the designer...
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...
Probing the Past
In Denver, Colorado, 12 buildings of an old abandoned brewery complex were to be renovated into a 270,000 sq ft shopping, entertainment and restaurant complex. Rather than conduct a thorough...
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...
Limiting Tip and Side Resistance: Fact or Fallacy?
The tip and side resistances of deep foundations do not reach a limit at a critical depth; instead, they increase with depth. For the tip, the rate of increase decreases with depth. For...
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...
Pile Foundation Design Using Pile Driving Analyzer
A case history of pile foundation design and construction for Pacific Bell's San Ramon Valley Administrative Complex is presented. Dynamic monitoring of driven piles with...
Role of a Standard in the Production of Drilled Shafts
The preparation of drawings and documents that describe the details of the installation of drilled shafts for a project requires an up-to-date standard. The role of the standard in the...
A Structural Engineering Perspective for Drilled Shafts
This commentary is an attempt to close the gap between the Building Code Requirements for Reinforced Concrete (ACE 318-83) and the design of drilled shafts. The context of design includes...
ASCE Drilled Shaft Standard: University Perspective
A critique is presented of the proposed ASCE standard on drilled shafts. Areas where major work is necessary relate primarily to the shaft design sections, establishment of loads, and...
Government Agency Perspective on Standard for Drilled Shafts
Relative to the proposed ASCE standard for Design and Construction of Drilled Shafts, the Tennessee Valley Authority (TVA) would be considered an 'owner'. However,...
Functional Specifications of a Distributed Engineering Data Management System
The development of a large-scale engineering data management system is outlined for AEC industries. Described are the outline specifications and basic design decisions used to implement...
Database Management
Computer aided design systems have found widespread acceptance from Engineering companies as drafting/detailing/drawing tools. While this has brought a dramatic productivity improvement...
Planning of CAE and CADD Centers
The factors to be considered prior to the establishment of computer aided engineering or computer aided design and drafting centers are discussed. It is noted that the critical issues...
Toward Interactive Color-Shaded Rendering in CAD
A software package (CATSIG) is described which allows the user to interactively color shade geometric objects created on a sophisticated commercial CAD system (CATIA). The novel features...
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...
