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...
Concrete Shells Today
Providing high structural qualities, modern shells using experimental forms will attract new attention due to their limitless repertory. Presented is a new form of construction, instead...
Nonlinear Behavior of Northlight Reinforced Concrete Shells
The behavior of northlight shells is very sensitive to the boundary conditions at the top and bottom edges of the shell. The aim of this paper is to investigate the structural action of...
Study on Reinforced Concrete Cylindrical Shells with Edge Members under Impact Loading
The strength, cracking patterns and the other nonlinear dynamic behaviors of reinforced concrete roof-type circular cylindrical shells influenced by edge member stiffness and supporting...
Nonlinear Analysis of a Reinforced Concrete Folded Plate Structure
This paper deals with the ultimate load analysis of a reinforced concrete (RC) folded plate shell subjected to dead load and monotonically increasing live loads, statically applied, using...
Spatial Structures Erected out of Thin Shell Elements Fabricated on Plane Followed by Bending
The paper offers the examples of spatial structures of average spans (up to 24 m) and engineering structures made of prefabricated curvilinear elements originally having a plane form....
Ultimate Strength of R/C Cooling Tower Shell
Reinforced concrete(R/C) cooling towers are the largest, thin shell structures. It is important to assess the ultimate strength of R/C cooling tower shells subjected to wind load. In the...
Repair of a Cracked Cooling Tower Shell Based on Numerical Simulations
The present condition of a 30 years old cooling tower shell made of reinforced concrete is characterized by a relatively large number of long, thermally induced meridional cracks. For...
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...
Punching Shear of Reinforced Concrete Shell Structures
In reinforced concrete shells punching shear failure may take place, if heavy concentrated loads are applied. Such failure is undesirable, since it does not provide adequate warning and...
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....
