A Generalized Approach to the Local Stability of Stiffened Plates: Part I?Mathematical Formulation
The paper describes a generalized approach for the determination of the buckling stress of stiffened plates under combination of uniform biaxial compression, in-plane bending and shear...

A Generalized Approach to the Local Stability of Stiffened Plates: Part II?Approximate Solution
The paper presents an approximate solution for the prediction of the buckling stress of stiffened plates under combined loadings. A closed form expression is presented for the buckling...

The Structural History of the Jacob Bachmann Tavern
The Jacob Bachmann Tavern is located in Easton, Pennsylvania. It is a collection of four interconnected buildings that have been constructed and modified over a period of 240 years. Structural...

LRFD vs. ASD for Wood Structures
There is a growing preference within the structural engineering community for the adoption of reliability-based load and resistance factor design (LRFD) procedures in lieu of traditional...

Fabric Roof Design Responds to New Technologies
A combination of newer synthetic materials and advanced structural design technologies have given contemporary tensioned fabric roofs vastly improved energy performance and far greater...

Nonlinear Behavior of Northlight Reinforced Concrete Shells
The behavior of northlight shells is very sensitive to the boundary conditions at the top and bottom edges of the shell. The aim of this paper is to investigate the structural action of...

Efficient Nonlinear Analysis of Column-Supported Cylinderical Shells
This paper presents a finite element methodology for the study of geometrically nonlinear behavior of column-supported cylinder. Due to the discrete nature of the column supports, the...

Elasto-Plastic Buckling Design for Shallow Cylindrical Shells under External Pressure
Pressures providing elastic-plastic buckling conditions for thin shallow cylindrical shell panels are presented. Classical simple support boundary conditions have been adopted for the...

History and Development of Fabric Structures
Except for the cave, the tent has been the dwelling for most nomadic peoples from the Ice Age to the present. Until recently, the three basic forms used are namely, the conical, the widespread...

The Body Language of Tensile Structures
Considered to be a 'body' and its visual appearance as 'non verbal, intuitable information,' a building has a Body Language that is employed as a primary mode. Presented is an intuitive...

Damage Tolerance Analysis in Structural Rehabilitation
The rehabilitation of existing structures requires an evaluation by the structural engineer of past performance to determine the extent of existing damage. Following evaluation of the...

Issues Related to Modeling the Transport of Suspended Sediments in Northern San Francisco Bay, California
Measurements of suspended sediment concentrations at several deep-channel stations in San Francisco Bay are reviewed. Sediment concentrations are found to be strongly correlated with delta...

Understanding the Uses of History in Water Resources Planning and Management
Understanding how water resources decisions (technical, regulatory, structural, or managerial) have been made is necessary to provide the water industry with a perception of complex human...

Computer Applications in Liquefaction Analysis
This paper discusses the applications of total and effective stress based computer programs for liquefaction analysis. A total stress based computer program, SHAKE in conjunction with...

Macroelement Model for Shear Wall Analysis
An efficient modeling scheme for static and dynamic analysis of reinforced concrete shear walls in the inelastic range is presented. The macroelement model of the shear wall is composed...

Extensions of Finite Element Dental Stress Analysis
Some two dimensional models for stress analysis of dental crowns are examined and compared in relation to boundary conditions and some other issues in finite element analysis. The current...

Rotating Crack Model and Fracture in a R/C Medium
In this study the potential of the development of cracks in the members of a reinforced concrete large panel structure is considered. The analysis is carried out using finite element modeling...

Numerical Modeling of Initial Ground Movement in an Instrumented Superconducting Super Collider Shaft
A 5.5 m diameter shaft was sunk into a rock formation of Taylor Marl to a depth of 61 m at the Superconducting Super collider (SSC) site. Numerical modeling using finite difference analysis...

Compressibility of Clays: Fundamental and Practical Aspects
The compressibility of natural clays is influenced by strain rate, temperature, sampling disturbance, stress path and some restructuration factors. The first part of the paper reviews...

Predicting Shallow Foundation Settlement in Sands from DMT
The dilatometer test is ideal for predicting the settlement of shallow foundations. It directly measures a modulus of the soil and has been correlated to predict stress history. Recently,...
