This paper reports research on the design of structures using genetic algorithms. It presents the design of a program that uses genetic algorithms to optimize a truss structure, along with an example of truss optimization.

All-metallic sandwich panels with truss and prismatic cores have impending application as ultra-light load bearing panels amenable to simultaneous active cooling and blast resistance. To facilitate application, a protocol for characterizing the structural performance of such panels is needed that can be used for design calculations. An approach capable of realizing this objective is presented a...

We introduce a truss decomposition algorithm for bipartite graphs. A subgraph G of a graph is called k-truss if there are at least k-2 triangles containing any edge e of G. By a standard breadth-first-search algorithm, we can compute the truss decomposition for large graphs. To extract a dense substructure that represents community in graph G, this method avoids the intractable problem of cliqu...

Actuators formed from piezoelectric ceramics were embedded in truss rods to make up active rods. The paper used mechanical knowledge, static stiffness method and the finite element method to analyze the active rod and the smart truss structure and then model them. In order to solve the difficult problem of number optimization, the paper put forward the actuator existence variable and optimized ...

1 Motivation Many large terrestrial structures—towers, bridges, construction scaffolds—are sparse assemblies of rigid bars connected together at structural nodes. This is also true of many in-space structures such as antennae, solar panel supports, and space-station members. A long-term application of truss climbing robots is automated assembly, repair, and inspection of such truss-like structu...

The present work deals with the structural optimization of self-supported Composite Steel Trussed-Concrete Beams (CSTCB). CSTCB belongs to category prefabricated steel truss embedded in a concrete core casted situ. is typically composed plate, which represents bottom chord, system diagonal bars and some coupled rebars working as upper chord. Optimized geometries lead minimization material use. ...

In order to assist students, gain conceptual understanding of internal forces, a physical manipulative of a truss was developed in order to help students visualize, feel, and analyze the behavior of the material being manipulated. The purpose of this qualitative study was to understand how a physical manipulative of a truss contributed to the conceptual understanding of truss analysis in static...

A new method for fabricating carbon fiber composite pyramidal truss cores was developed based on the molding hot-press technique. In this method, all the continuous fibers of composite are aligned in the direction of struts and thus, the truss structure can fully exploit the intrinsic strength of the fiber reinforced composite. The microstructure and organizations of fibers of fabricated compos...

This study is to analyse the dynamical instability (or the buckling) of a steel space truss using the accurate solutions obtained by the high-order Taylor series method. One is used to obtain numerical solutions for analysing instability, because it is difficult to find the analytic solution for a geometrical nonlinearity system. However, numerical solutions can yield incorrect analyses in the ...

Abstract For industrial applications, truss robots can perform mutipleoperations, such as transporting objects and handling tools independently, but face the challenges of inconvenient disassembly non-recyclability. Therefore, a robot load-bearing module based on spatial bar structure is designed, which consists bars connectors. Ansys Workbench used for static analysis beam. The results show th...
