Study on Structural Characteristics of Air-Inflated Beam Structures
The purpose of this paper is to clarify the structural characteristics of nonlinear load-carrying behaviors of air-inflated beam structures in their finite deflection range and after wrinkles...
Expandable Structures with Incorporated Roofing Elements
In this paper design aspects of expandable structures with incorporated cover plates are studied. These roofing elements can be made by single plates or by self-folding plates. In both...
Intermediate Support Cable Logging Systems
Cable systems for the transportation of fresh cut logs often employ existing trees as intermediate supports for the main support cable. Failure of these support trees is life threatening...
Transient Response of Guyed Telecommunication Towers Subjected to Cable Ice-Shedding
This paper presents the results of a numerical study of the transient response of guyed telecommunication towers subjected to sudden ice shedding from the guy wires. Detailed nonlinear...
Study on Reinforced Concrete Cylindrical Shells with Edge Members under Impact Loading
The strength, cracking patterns and the other nonlinear dynamic behaviors of reinforced concrete roof-type circular cylindrical shells influenced by edge member stiffness and supporting...
Nonlinear Analysis of a Reinforced Concrete Folded Plate Structure
This paper deals with the ultimate load analysis of a reinforced concrete (RC) folded plate shell subjected to dead load and monotonically increasing live loads, statically applied, using...
Ultimate Strength of R/C Cooling Tower Shell
Reinforced concrete(R/C) cooling towers are the largest, thin shell structures. It is important to assess the ultimate strength of R/C cooling tower shells subjected to wind load. In the...
Punching Shear of Reinforced Concrete Shell Structures
In reinforced concrete shells punching shear failure may take place, if heavy concentrated loads are applied. Such failure is undesirable, since it does not provide adequate warning and...
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...
Performance and Analysis of Frames With URM Infills
The interaction of unreinforced hollow concrete block masonry (URM) infill walls and gravity load designed (GLD) frames has been studied at Cornell University. The primary goal of this...
Lateral Response of Unreinforced Masonry Infill Frame Panels
This paper presents the results of the out-of-plane testing phase of the National Science Foundation Grant BCS 9102347. This project addresses the out-of-plane response to lateral loading...
How to Optimize Frames Using Plastic Design Concept
An optimal design procedure using plastic design concept was presented. For low-rise building frames, optimal plastic designs can be made using the plastic limit load as a basis of design....
Optimization for Earthquake Loads
Structural optimization for seismic loads can be approached from a deterministic or nondeterministic point of view. Deterministically, the major difference between optimization of statically...
Flange Local Buckling and Behavior of I-Sections
A simple kinematic model is proposed to determine the locally buckled shape of the compressive flange plate of I-sections subjected to pure bending or bending combined with axial thrust....
Digital Signal Processing Techniques for Active Structural Control
In the past, implementation of active structural control strategies employing PC-based hardware has been problematic due to excessive computational times required for processing the measured...
A Numerical Study of Hydraulic Jump and Mixing in a Stratified Channel With a Sill
An x-z plane two dimensional primitive equation model is used to study sill effects in a narrow channel. The aim is to examine the generation of internal bores/waves, hydraulic jumps and...
Tributary Loading with a Terrain Following Coordinate System
The modeling of physical processes that occur in a tributary between the farthest downstream gage and the lake interface can help to improve the predictive capabilities of Great Lakes...
Design, Construction, and Maintenance of Relief Wells
Technical Engineering and Design Guides, as adapted from the U.S. Army Corps of Engineers, No. 3 This engineering manual provides guidance and information...
Low-frequency Fluctuations of Suspended Sand and Wave Groups in the Surf Zone
Field observations of the sand suspension near the bottom in surf zone are presented and discussed. Calculated spectra of suspended sand concentration and wave envelope was found to be...
