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....
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...
Wave Transformation and Load Reduction Using a Small Tandem Reef Breakwater ? Physical Model Tests
The performance of several small reef breakwaters, and a tandem breakwater system (consisting of a reef breakwater positioned upwave from a surface-piercing main breakwater), are quantified...
Dynamic Loading of Airfield Pavements Caused by Aircraft Operations on Rough Runways
This paper presents results for dynamic pavement loading of various aircraft under takeoff and taxing scenarios. The data were obtained from computer simulation and applied to the Corps...
Environment-Friendly Deicing/Anti-Icing Fluid
NASA Ames has formulated a unique candidate non-glycol based freezing point depressant (FPD) fluid material that performs essentially the same or superior to currently used glycol based...
Prediction of Gravel Bedload with SAM
Bedload measurements for Little Beaver Creek in Colorado were used to test the sediment transport functions included in SAM. The test results showed that Toffaleti predicts total bedload...
Partnering in Environmental Restoration: The Coastal America Model
The Coastal America Partnership was initiated in 1993 with the underlying principal that collaborative efforts would be more successful than attempting individual agency solutions. To...
An Integrated Approach to the Real-Time Control of Water Supply and Distribution Systems
In recent years, real-time automated operation and control schemes have been implemented for a number of water supply and distribution systems with varying degrees of success. This paper...
Concrete Watertight Structures and Hazardous Liquid Containment
The purpose of
MPOS Become VIPS
The 1991 Intermodal Surface Transportation Efficiency Act made metropolitan planning organizations very important players in transportation decisionmaking. MPOs have been around since...
