What Controls the Ultimate Load of a Glulam Dome?
A glulam dome is analyzed with the finite element method to determine the governing failure mode and ultimate snow loads. The dome consists of a triangulated network of curved glulam beams,...
Structural Failure and Quality Assurance of Space Frames
Space frame has been developed rapidly in China and used to wide extent to cover various types of buildings. The large scale of application will unavoidably cause quality problems. Damages...
AWS versus AIJ Tubular K-Connection Design Rules
Among various existing design rules for circular tubular connections, the AWS rules are compared with the AIJ rules because of differences between the two. Subjects of discussion include...
Response of Truss Structures Subjected to Dynamic Loads During Member Failure
The paper presents a method for and results from an investigation of the response of a truss structure during the chain reaction of its member failure while subjected to external static...
Structural Integrity of Space Trusses
Space trusses of the double layer grid configuration can experience rapid propagation of failure in the ultimate load condition and thus are potentially vulnerable to progressive collapse...
Collapse Behavior of Double-Layer Space Truss Grids with Member Buckling
The results of collapse tests of over twenty space truss grids with elastic buckling of members are reviewed. The space truss grids include three types, that is, square-on-square, square-on-diagonal...
Membrane Structures: Technological Innovation and Architectural Opportunity
Presented is a list of materials used in building an airhouse. There are so many other moves in tensile structures and the present interest is in ETFE foils because of light transmission/cost...
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...
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...
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...
Nonlinear Earthquake Analysis of Concrete Gravity Dams Including Sliding
The sliding stability of a concrete gravity dam during a design earthquake must be investigated to assess the seismic safety of the dam. A new numerical procedure for solving the equations...
Fast Monte Carlo Simulations and Safety Index Checking
This paper presents recent techniques which require a small number of simulations to assess the structural reliability. They combine both the concept of importance zones in the random...
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...
Tailwater Fishery Management Using a Fish Bioenergetics Model
Water releases from TVA reservoirs exert great influence on downstream water quality. Analytical tools to quantify biological response to altered environmental conditions, such as dissolved...
Changing Dam Operating Criteria to Accommodate Aquatic Biological Diversity
The Colorado squawfish, bonytail chub, humpback chub, and razorback sucker, now threatened with extinction, were once the dominant fishes in the river. Recovering these native species...
Integration of Reliability, Uncertainty and Optimization in Hydraulics Systems: Structural Reliability
The focus of this paper is to provide an overview of analysis and optimal design of systems in which the system reliability is dependent upon the structure of the system (such as the layout...
Designing Optimal Reliable Multiquality Water Supply Systems
A methodology which integrates optimal design and reliability of a multiquality water supply system is presented and demonstrated. The system constructed is able to sustain prescribed...
Nakajima Subsurface Dam
A new water resource is generated by a subsurface dam. This paper presents the design, construction, and monitoring of a test subsurface dam in an alluvial valley of an island for both...
Simulating Hourly Hydropower Operations for the Assessment of Environmental and Economic Impact
Generation of peaking power at Glen Canyon Dam causes river flow and stage to fluctuate on an hourly basis. This has been shown to impact the downstream physical and biological environment....
Dam Safety Issues Related to Urban Detention Ponds
Detention ponds located within or adjacent to individual residential developments provide significant benefits by improving water quality and preventing damages from floods up to the design...
