Dynamic Analysis of Unstable Structural Systems With Prescribed Velocities
Structural systems that have large inextentional deformation, or in other words, deformation without stain are called 'Unstable Structural Systems.' They include cable structures, membrane...
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...
Comparison of Two different Models of a Shell Roof
The main purpose of this study is to compare a physical model of a shell roof with a theoretical model of the same shell roof in order to verify the reliability of the Homeostatic Model...
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...
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...
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...
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,...
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...
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...
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...
Design for Durability for Large Reinforced Concrete Shells
Classical design concepts restrict themselves to sufficient structural safety, using linear analysis methods. Durability questions are mainly treated independently. Modern computer simulations...
Stability Analysis of Stiffened Plates and Shells
A stability analysis of stiffened plates and shells by using degenerated finite elements is presented. The studies are based on a thin shell theory, large deflections, but on an elastic...
Morphology of Reciprocal Frame Three-Dimensional Grillage Structures
This paper is an introduction to the morphology of structures using the Reciprocal Frame (also known as Mandala Dach in Germany) which is a patented three-dimensional beam grillage structural...
Integrated Research for Civil Infrastructure Systems: A Future Challenge
The paper presents a research program developed at NSF for the improvement and renewal of the nation's civil infrastructure systems. The proposed program is integrated, multi-disciplinary,...
