Deployable Mesh Reflector
This paper presents a new deployable reflector for space applications, based on a deployable edge frame that deploys and prestresses a 'rigid' cable network. The edge frame consists of...

An Application of Inverse Problem Techniques to Spatial Structures
The present paper attempts to give a definition of inverse problems for spatial structures, and to develop a design method to find the optimum configurations and shapes for such structures...

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...

Experimental Study on a Buckling Behavior of a Wooden Single-Layer Space Frame of Reticular Shell on a Hexagonal Plan: Influence due to the Bolted Joint Looseness with Axial and Bending Resistance
The authors have investigated about the structural behavior of a wooden single-layer space frame structure with the bolted joints. We have carried out a buckling tests of a wooden single-layer...

On some Problems of the Multicriteria Optimization of the Spatial Grid Structures
One can not think contemporary structure designed without consciously complying with optimization methods. Creative activity of engineers have to be optimal or semi-optimal. It is necessary...

The Behaviour and Design of Stressed-Arch (Strarch) Frames
The paper presents an overview of the stressed-arch structural system and the associated research program undertaken at the University of Sydney between 1988 and 1992. The objectives of...

Research and Application of Various Joints of Space Grid Structures in China
This paper introduces the research work results and applications of various joints of space grid structures in China. It also gives out formulas for determining the loading capacity and...

Sensitivity and Optimum Structural Design
Modern design requires more advanced considerations leading to light and safe structures. One of the way to reach this aim is through structural optimization. Today's computational possibilities...

Possibilities and Problems of Latticed Structures
Several fundamental aspects of space frames which are sometimes referred to as latticed structures are discussed. Terminology of the structural system is first considered. Special features...

Project Case Study: Space Frame Roof Structure, Main Stadium, Shah Alam Sport Complex, Selangor, Malaysia
In the city of Shah Alam located just outside of Kuala Lumpur, the Shah Alam Sport Complex is built as a multi-use sports facility. The aim of this study is to discuss the management of...

Analysis and Design of a Double Layer Barrel Vault with a Large Span
The roof of coal storage in JiaXin Power Station is a double-layer barrel vault. This roof covers span of 103.5 M and a longitudinal span of 88.0 M. The height of this space truss is 3.5...

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...

Optimization of Space Lattice Structures with Multimodal Frequency Constraints
The paper presents an optimization algorithm for the design of space trusses subjected to constant value constraint. The goal of the optimization is a structure of the highest multiple...

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...

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...

The Nature of Structural Morphology and Some Interdisciplinary Examples
Among members of IASS, the most common definition of Structural Morphology is the study of interaction between geometrical form and structural behavior. The most significant structural...

Tensegrity Structures: Filling the Gap Between Art and Science
Underlining the role of structuralism in contemporary architecture this paper addresses the application of structural morphology in the context of an educational experience. Focussing...

Space Frames and Polyhedra
Polyhedra are easy to build and they can be useful as architectural matrices. Relatively small polyhedra can be built as faceted structures; very large ones can be built with space frames....

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...

Hyper-Geodesic Structures: Excerpts from a Visual Catalog
A class of hyper-geodesic surface structures is presented. The surfaces of known polygons, polyhedra, plane and space tessellations, higher dimensional polytopes can be subdivided into...
