Fabric Structures for Public Buildings
The design of the enclosure structure of the new Denver Airport derived from twenty years of experience with the design and engineering of fabric structures for permanent buildings. This...

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...

Study on Mechanical Characteristics of Light-weight Complex Structure Composed of a Membrane and a Beam String Structure
This paper aims at studying a new type of Beam String Structure, in which a membrane is used as finishing material. This paper reports on the mechanical characteristics of this structure,...

Combinatary Net-Shell Roofs of Elliptic Paraboloid of Zhaoqing Gymnasium
Zhaoqing Gymnasium is a multi-functional sports building, whose structural modelling takes Zhaoqing City Flower(Lotus) as the main theme; adopts a combinatory ellipic paraboloid net-shell...

Effects of Spatial Triangulation on the Behavior of Tensegrity Domes
A number of long span 'tensegrity' dome type structures have recently been realized pursuant to the inventions of R. Buckminster Fuller and David H. Geiger. These structures have demonstrated...

Active Control of Axial Forces in Beam String Space Frames
The present work discusses a formulation for active control of axial forces of strings in beam string structures to dynamically and/or statically reduce the responses, and proves both...

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...

A Practical Design and Construction of Tension Rod Supported Glazing
In designing a glass skin-covered space, for the atrium, entrance hall or other core part of a building complex, the high openness and quality requirements of the space often lead to the...

Form Finding Numerical Methods for Tensegrity Systems
The rigidification of Tensegrity Systems is related to selfstress states which can be achieved only when geometrical and mechanical requirements are simultaneously satisfied. This paper...

Direct and Modal Analyses for Shape-Finding of Unstable Structures
Shape-finding analysis of unstable structures has been presented by using generalized inverse (Tanaka and Hangai, 1986). The 'Modal Analysis' using rigid body modes is elegant, but the...

A Shape-Finding Finite Element Analysis for an Equally-Stressed Surface in Membrane Structures
A finite element method is proposed to obtain an equally-stressed surface in a membrane structure, where the displacements and rotations of a membrane are in general finite and nonlinear....

Vibration Characteristics of Suspension Membrane Structures
The present paper specifies fundamental vibration characteristics obtained from experiment on the model of the suspension or the framed membrane structure. The first paragraph describes...

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...

Seismic Performance and Retrofit of the Golden Gate Bridge
Since its opening in 1937, the Golden Gate Bridge has endured and functions as an important transportation link for Bay Area commerce and commuters. After an earthquake in 1989, T.Y. Lin...

Innovations in Major Suspension Bridge Design
Before the Tacoma disaster, the trend in bridge-building is on increasing slenderness. But since its occurrence, a high degree of aerodynamic stability is required. Presented are designs...

Akashi-Kaikyo Bridge Underconstruction
This paper presents 1) brief history of the survey work, 2) brief description of the physical dimensions and structural system, 3) major studies for the design, 4) development of higher...
