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...
Time-Domain Dam-Reservoir-Interaction Analysis Based on Boundary Elements
For a reservoir with an arbitrary shape of the upstream face and of the bottom including an adjacent regular part of constant depth extending to infinity, the hydrodynamic-stiffness matrix...
Dynamic Simulation of Foundations on Winkler Subgrade
The objective of this paper is to present a dynamic simulation of foundations on Winkler subgrade. The analysis is based on a direct simulation procedure. The structures have been modeled...
Combined Finite Difference/Finite Element Analysis for Soil Structure Interaction
A method for the analysis of buried structures subjected to stress transients is presented. The method combines the finite difference and finite element techniques to provide the analyst...
Lateral Impedance of Contact Pile Foundations
The static and dynamic lateral impedance of pile foundations for which there is continuous contact between the bottom of the pilecap and the underlying soil is investigated. A parametric...
Dynamic Response of Massive Block to Transient Rayleigh Waves
The study explores the dynamic behavior of a rigid massive block placed on a homogeneous elastic half-space soil medium and subjected to transient Rayleigh waves. The treatment of the...
Stability and Limit Loads of Steel Space Trusses
An investigation of the behavior of cold-formed steel space truss structures, under the interaction of local, member, and overall buckling is described. A Finite Element computer program...
Buckling of Thin-Walled Members by p-Version of FEM
P-Version of the finite element method (FEM) is used for one-D and three-D modeling of thin-walled open sections and axial compressive load. Equal angle and channel sections are used for...
Behavior and Design of Semi-Rigid Composite Frames
Recent advances and experimental research on the behavior of composite semi-rigid frames indicates that substantial savings can be achieved with this method of construction. The current...
Frame Stability
The Chapter on Frame Stability of the Fourth Edition of the SSRC Guide provides guidance on use of several stability design procedures. These include Critical Load Concept, Second-Order...
Dynamic Fracture Toughness of Rail Steels
As new premium alloy rail steels exhibit increased wear resistance and as track lubrication is used, the failure mode for rails is shifting from wear to fatigue. Elastodynamic finite element...
Design of Steel Buildings for Second Order Effects
Several methods of calculating corrected effective length factors for unbraced frames are presented and discussed. In addition, an alternate format is suggested for the ASD beam-column...
Sewer-Septic Tank Hybrid Promises Savings
Until recently the only options for sewage were the septic tank/leach field or conventional sewers. In some cases a hybrid of the two, called the septic tank/effluent drain, is less costly...
