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...

Optimal Design Conception of Grid Domes in Practice
In this paper, the optimal design conception of grid domes in practice is presented. The classical dome shell structures covering some irregular boundaries often seems not to be satisfied...

Explorations in Geodesic Forms
Geodesic forms constitute an important family of structural systems. The objective of the paper is to show how the concepts of a mathematical tool called formex algebra and its programming...

Discrete Field Stability Analysis of X-Braced Lattices
The three-dimensional X-braced lattice is used as a compression member in structures ranging from the long span roof of buildings to radio and television antennas. In such cases the design...

Simulation Procedure for Buckling Behaviors of a Reticular Dome
Complex behaviors of the ball-joint connection, especially used in steel space structures, are expressed in the numerical model to confirm the estimative ability of such a model by comparing...

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,...

Buckling of Single Layer Latticed Dome under Uniform Gravity Load
This paper reports on experiment and numerical analysis relating the buckling of a single layer latticed dome under uniformly distributed nodal gravity load at the dome central portion....

Nonlinear Buckling Response of Single Layer Latticed Barrel Vaults
Elastic overall buckling of single layer latticed barrel vault roof structures under static vertical loading is investigated using a fully nonlinear finite element solution procedure and...

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...

Georgia Dome Cable Roof Construction Techniques
This paper will provide a case study of the construction of the Hypar-Tensegrity Cable Roof for the Georgia Dome. The paper will emphasize innovative computer analysis of the construction...

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,...

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...
