Damage Prediction in Reinforced Concrete Structures under Cyclic Loading
Assessment of the stiffness, resistance and damage behaviour of reinforced concrete members under high cyclic loading due to earthquake actions must consider material nonlinear effects...

Continuous Pulse Control of Structures with Material Nonlinearity
A control method is presented for reducing the dynamic response of structures in the inelastic material range using a control force from an active control system. The proposed method of...

Imperfections and Thin-Walled Bars Behaviour
Experimental and theoretical observations allowed us to present some new conclusions concerning the proper, and safe designing of the structures composed of thin-walled bars (TWB). These...

Research of Strength and Deformations with Long-time Loading and the Use of Glassfiber Reinforced Concrete in Shells
Presented is an experimental research on the properties of behavior on compression and tension of glassfiber reinforced concrete of alkali-resistant glass fiber under long-time load and...

Large Deformation Analysis of Lattice Truss Structures Including Hysteretic Material Behavior
A methodology is presented to analyze lattice truss structures including both material and geometric nonlinearities. Modeled member material behavior modes include: buckling, yielding,...

Ultimate Loading Capacity of Braced Domes
The stability behaviors of a practical latticed dome with 40 metres span are studied in this paper. The geometric and material nonlinear behaviors, as well as the effects of the initial...

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...

Helium-Supported Hangar for a Small Solar-Powered Airship
For the IGA Expo '93 the Institute for Statics and Dynamics of Aerospace Structures, University of Stuttgart, together with Stuttgart Solar e.V. developed a solar-powered airship. For...

Wall Relief and Three Dimensional Suspension Sculpture Utilizing Tension and Membrane Structures
The aesthetic concerns and observations on sculptural forms involve tension and membrane structures. In the following discussion, the textile forms, which strongly influenced the more...

Current State of Development and Future Trends in Employment of Air-Supported Roofs in Long-Span Applications
Considered here is the low-profile, long span air-supported roof, as opposed to the high-profile 'bubble' variety, which has seen a substantially different development and expectation....

The Use of ETFE Foils in Lightweight Roof Constructions
ETFE foils are polymer film sheets which are enclosed in support frames and inflated to provide stable, insulated and transparent roof cushions for lightweight enclosures. This paper describes...

Fabric Roof Design Responds to New Technologies
A combination of newer synthetic materials and advanced structural design technologies have given contemporary tensioned fabric roofs vastly improved energy performance and far greater...

Elasto - Plastic Analysis of Cable Net Structures
This paper presents a Newton-Raphson interaction technique which takes account of plastic cable strains while iterating on the nodal equilibrium equations of cable net structures. The...

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...

A Quasicrystal for Denmark's Coast
The first true quasicrystal structure will have been built in the fall of 1993 at COAST (The Center for Art, Science, and Technology at the Danish Technical University). With 600 aluminum...

Some Applications of Neural Networks in Structural Engineering
After a brief discussion of neural networks and their potential engineering applications, the author's on-going research in application of neural networks in structural engineering will...

How to Optimize Light-Gage, Cold-Formed Steel Beams
The Illustrative Examples section of the AISI Cold-Formed Steel Design Manual (AISI 1989) demonstrates how to analyze a number of different cold-formed steel sections. This paper applies...

Structural Analysis for Structural Design
This paper presents a simple extension to conventional structural analysis that serves to provide additional information that is of significant use to the structural design process. Specifically,...

Computer-Aided Structural Engineering Software: The Status of Concurrent Engineering
Concurrent engineering encompasses computer-aided engineering (CAE), multidisciplinary CAE (MCAE), computer-aided design and drafting (CADD), computer-aided manufacturing (CAM), computer...

Assessing Effects for Disposal Sites off San Francisco
A simple particle tracking model has been used to estimate the size of deposition footprints and transient turbidity effects in the water column resulting from disposal of dredged material...
