Why Bifurcation: A Study of a Reticulated Dome
Numerical results for a hexagonal lattice dome subjected to uniform gravity loading are presented. We demonstrate that a perfect nonlinear bifurcation analysis plays a crucial role in...
Buckling Criteria for Earthquake-Induced Overturning Stresses in Cylindrical Liquid Storage Tanks
Perhaps one of the most common forms of seismic damage to cylindrical liquid storage tanks made out of steel is buckling of the tank wall due to vertical overturning stresses. Buckling...
Static Tilt Analyses of Uplifting Cylindrical Tank
This paper describes the general method adopted for predicting the static tilt performance of cylindrical liquid storage tank that is free to uplift. In the analysis described here, the...
Bullwinkle
The 1989 Outstanding Civil Engineering Achievement is an offshore oil production platform named Bullwinkle, a structure in the Gulf of Mexico that is taller than the Sears Tower, shaped...
Structures for the Moon
Lunar structures present new challenges for structural engineers. By articulating lunar conditions in terms of various 'causes,' e.g. high transportation costs...
Caissons Skirt a Tunnel
Exchange Place Center is a 490 ft, 30 story office tower built directly over the existing transportation hub in Jersey City, N.J., where trains and buses meet the PATH Tubes that carry...
Computer Aided Simulation of Fluid-Structure Interaction Problems
The papers included in this book represent state-of-the-art developments in and applications of computer aided simulation of fluid-structure interaction problems in both the terrestrial...
Stability of Cylindrical Shells With and Without Cutouts and Subjected to Wind Load
The cylindrical storage tanks with and without cutouts are analyzed using nonlinear finite element analysis. All the cylinders are fixed at the base. Two types of cylindrical tanks without...
Circular Tubes and Shells 4th Edition of SSRC Guide
The 3rd edition of the Guide was the first to have a chapter devoted to Cylindrical Tubes and Shells. Chapter 14 in the 4th edition is a major revision of Chapter 10 in the previous edition....
Concrete Shell Design for Membrane Stress
A methodology is presented which covers the design of reinforced concrete shells for membrane stress. The methodology follows the strength design method of the ACI 318-83 Building Code...
Ultimate Membrane Strength of R/C Shell Elements
The ultimate strength of reinforced concrete shell elements is governed by the yielding of steel and/or the compressive strength of concrete. Depending on which of these two conditions...
The Ultimate Load Design Method of R/C and P/C Shell
Based on the testing results of 20 full size shells and models, the ultimate load analysis method is proposed to design four different kinds of reinforced concrete shallow shell structures....
Substitute Wind Concept for Elastic Stability of Cooling Tower Shells
The influence of the nonaxisymmetric wind distribution on the stability behavior of cooling tower shells is examined. It is demonstrated, considering about 50 cooling tower shells, that...
Materials and Member Behavior
Each of the papers in this book covers some aspect of material properties. New developments in cold formed steel are reviewed. The strength, stiffness, and ductility of steel connections...
Heterosis Shell Element in GTSTRUDL
The most popular shell finite element is the degenerated solid type, originally formulated to model thick shells. However, in thin shell applications, this element fails by 'locking'....
Frequency Domain Analysis of a Tank-Soil System
The dynamic response of an elastic cylindrical tank supported on a rigid base under a harmonic vertical excitation is analyzed taking into consideration its interaction with the foundation...
Earthquake Analysis of Liquid Storage Tanks
In the design of modern liquid storage tanks, it is of technical importance to examine their safety against earthquake damage. The methodologies used in design do not account for the major...
Nonlinear Quasi-Static and Transient Response Analysis of Shallow Shells: Formulations and Interior/Boundary Element Algorithms
Nonlinear integral equations are derived for the representation of displacements of shallow shells undergoing moderately large, quasi-static or dynamic deformations. A combined interior/boundary...
Response of Concrete Shell Panels to Simulated Impact
Concrete gravity structures have been constructed in Arctic regions for oil and gas exploration/production. In addition to extreme winds and waves, sheet ice, annual ridges, rubble fields,...
Arctic Drilling and Production Platform Concept
An 80-well Arctic drilling and production platform for water depths to 100 feet in the Beaufort Sea transition ice zone is presented. It includes a novel inner caisson to help resist large...
