Distributed Construction of Truss Structures
2013We address the construction of truss structures with standardized parts and simple fasteners using multiple aerial robots. Robotic construction, unlike assembly in industrial settings, often occurs in unstructured environments where it may be difficult to manipulate objects to a high level of precision.

The presentation of the finite element method starts in this chapter with the explanation of the finite element method for truss and beam systems. The concept of stiffness matrices is shown first for a simple truss element. The procedure for setting up the equations for a finite element analysis is explained exemplary for a simple truss system.

A Numerical Stability Study on Truss Structures
Revue Européenne des Éléments Finis, 1992Summary: This paper, which presents a numerical study on nonlinear stability problems of truss structures, concentrates on three main parts. First, the derivative of the tangential stiffness matrix is used to give the stability analysis with direct calculation of the critical points and the branch-switching function. And then a quadratically convergent

As we described in Chap. 7, there are several main types of structural elements. In this chapter, we will discuss ways to find the internal forces acting in structures. Structures may be spatial or planar. For example, if all of the structure members and loads belong to the same plane, we will call such a structure planar.

A force method is proposed to analyze and optimize adaptive truss structures. It is observed that the structural strength is improved significantly using the adaptively optimized geometries while the computational effort required by the force method is found to be significantly lower than that of the displacement method.

Recent trends in underwater vehicle design suggest the use of trusslike structures to support vibrating machinery. Experimental measurements are used to understand the dynamic behavior of a set of 1:15 model, three-dimensional truss structures over the full scale equivalent frequency range 10–1400 Hz.

Analysis on dynamic response of truss structure for deployable truss antenna
2011 9th World Congress on Intelligent Control and Automation, 2011Analysis on dynamic response is one of the important parts of structure analysis for space deployable antenna. To study the dynamic response characteristics of truss structure for deployable truss antenna, according to the structure characteristics of truss structure, the finite element model is built by using ANSYS software.

Truss Optimization In Aerospace Structures
SAE Technical Paper Series, 2001<div class="htmlview paragraph">This work presents an approach for the structural optimization of 2D and 3D aerospace truss structures. The main goal is to reduce the volume (or weight) of the structure while satisfying constraints such as compliance, member stresses, local or global buckling, for one or more load cases.
