Collapse behaviour of double layer grid structures in steel
Flat double layer grid (DLG) structures are efficient modular, structural systems which span in two or more directions and consequently develop their resistance in three dimensions. Although such structures offer many structural, constructional and aesthetic advantages over alternative planar …

Manufacturing Quality of Carbon/Epoxy IsoTruss (R) Reinforced Concrete Structures
… of hand-manufactured carbon-epoxy IsoTruss® grid structures for use as reinforcement in concrete piles. Large IsoTruss® grid structures were manufactured and embedded in 14.0" (35.6 cm) diameter concrete to create IsoPiles™. The IsoPiles™ were designed to have flexural characteristics …

Grid Structure and Space
… architects to use steel as the material in grid structure buildings. For example, rising real estate prices, the advent of the safety elevator and availability of cost effective steel members. After that, grid structures play a very important role in modern architectural history. Now, …

Modeling and Hybrid Simulation of on-Chip Power Delivery Network Using an Unconditionally Stable Electromagnetic Field Solver
… layer-centric domain decomposition of the power grid. The domain decomposition approach used relies on the iterative exchange of field information between adjacent subdomains over an overlap region. For the case of on-chip power grid structures, it is shown that at most two iterations are needed …

Design approaches to structural optimization
… In the example of three-dimensional grid structures, widely known as 'space frames', possible configurations are explored which maximize the load-bearing capacity of the system in relation to its weight. The study has been organized in two chapters: The first chapter starts with a …

Spatial context as an aid to page layout : a system for planning and sketching
… by their dimensions and have areas delineated by grid structures. The pages become the structure upon which the design problem is mapped out. Text and image areas are defined and modified dynamically. Series of pages constitute the spatial context and can be combined, ordered, and arranged. Using …

Inelastic Analysis of Reinforced Concrete Beams Subjected to Combined Axial Force, Bending and Torsion
… the space truss model is used in the analysis of grid structures on which torsion is known to be significant. By comparison with available experimental data as well as examination of the behavior of the model in extreme conditions, the use of the structural mechanism of the space truss model is …

DGM-FD: A Finite Difference Scheme Based on the Discontinuous Galerkin Method
… and effective adaptability to different mesh structures. Finite difference and finite element methods are commonly used numerical schemes in CAA. Finite difference methods have the advantages of ease of use as well as high order convergence, but often require a uniform grid, and stable …

Optimal coordination of distributed energy resources in smart grids enabled by distributed optimization and transactive energy
Modern active distribution grids are characterized by the increasing penetration of distributed energy resources (DERs). The proper coordination and scheduling of a large numbers of these DERs can only be achieved at the nexus of new technological approaches and policies, primarily distributed …

Predicted Redidual Strength of Damaged IsoTruss® Structures
… damage in traditional single and hybrid-grid IsoTruss® structures. Residual strength was studied for structures subjected to axial compression, torsion and flexural bending, independently. Carbon/epoxy material properties were applied in all load cases, and fiberglass/epoxy material …

Influence of Consolidation and Interweaving on Compression Behavior of IsoTruss™ Structures
<p>Composite IsoTruss™ structures incorporate intersecting longitudinal and helical members. At the intersections, the fiber tows can be interwoven to achieve mechanical interlocking for increased joint integrity. Interlocking introduces gaps and curvilinear fiber paths similar to the crossovers in …
