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...
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...
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...
Computer Modelling of Comminuting Granular Media
Using generalized continuum mechanics, generalized damage theories for granular materials in comminution processes are proposed. The generalization is accomplished by treating the average...
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,...
Vertical and Horizontal Deformations for Foundations on Sand: An Experimental Study
A natural scale model is used in order to investigate experimentally the sand soil deformation behavior which accepts loads by shallow foundations. The vertical and horizontal soil displacements...
Settlement of Shallow Foundations on Sand
A new method for estimating the settlement of shallow foundations on sand is presented. The method is based on elastic stress-strain theory and is designed for use with soil data from...
