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...
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...
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...
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...
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...
Performance and Analysis of Frames With URM Infills
The interaction of unreinforced hollow concrete block masonry (URM) infill walls and gravity load designed (GLD) frames has been studied at Cornell University. The primary goal of this...
Behaviour of Concrete Masonry Infill - Steel Frame Structures
Twenty-eight masonry shear panels infilled in steel frames were tested to ultimate strength under in-plane, horizontal loading applied at roof level. The parameters investigated in this...
Experimental Evaluation and Finite Element Analysis of Masonry-Infilled R/C Frames
Eleven tests were conducted on 1/2-scale, single-story infilled frame specimens to study the influence of the relative strengths of the infill panels and the bounding frames and the frame...
How to Optimize Frames Using Plastic Design Concept
An optimal design procedure using plastic design concept was presented. For low-rise building frames, optimal plastic designs can be made using the plastic limit load as a basis of design....
RC Beam-Column Element for Nonlinear Frame Analysis
Recent studies have shown that beam-column finite elements that enforce equilibrium rather than compatibility along the element are better suited for the description of the strength and...
Plate and Frame Membrane Air Stripping
This paper examines utilization of a plate and frame membrane air stripping system for the removal of volatile organic chemicals (VOCs) and radon from a water supply. Previous work explored...
Success Syndrome: The Collapse of the Dee Bridge
Scaling up existing successful designs can cause latent weaknesses to become dominant, leading to catastrophe. By studying past failures where this has happened--for example, the 1847...
