Traditional truss design and analysis assumes pinned joints at the connections. Other design provisions recommend that the trusses be designed and analyzed as frame structures, with careful consideration of the stress, timber behavior, and joint response. A large body of knowledge has been compiled detailing truss behavior as it relates to member properties and responses. However, the modeling ...
1. Abstract Use of decomposition-based design optimization methods requires a priori selection of system partitioning and of the corresponding coordination strategy. Typically, partitioning systems into smaller, easier to solve subproblems leads to more complicated, computationally expensive coordination strategies. Previous optimal partitioning techniques have not addressed the coordination is...
In the design of a mechanical structure, we’re interested in finding a general layout of the structure’s supporting frame that best supports some anticipated design loads. Often, the design of such supporting frames are addressed in ad-hoc ways, such as by complicated domain-specific heuristics [TTG05, DG01]. Our project targets the problem of designing a truss–a collection of bars rigidly atta...
In this paper, an efficient technique is presented for static analysis of tall buildings with combined tube-in-tube and outrigger-belt truss system while considering shear lag effects. In the process of replacing the discrete structure with an elastically equivalent continuous one, the structure is modeled as two parallel cantilevered flexural-shear beams that are constrained at the outrigger-b...
The transverse compression and shear collapse mechanisms of a second order, hierarchical corrugated truss structure have been analyzed. The two competing collapse modes of a first order corrugated truss are elastic buckling or plastic yielding of the truss members. In second order trusses, elastic buckling and yielding of the larger and smaller struts, shear buckling of the larger struts, and w...
recent developments in the area of smart structures indicate that variable geometry / stiffness truss network is of fundamental importance in designing smart transformable structures and systems for space applications. this paper presents the conceptual design and dynamic modeling of a cooperative re-configurabel dual-arm robotic structure called dual-arm cam-lock manipulator. the manipulator i...
Schizothorax curvifrons is a morphometrically and meristically most variable and economically valuable promising fish food from Kashmir Valley. Since there is a lack of information on stock structure of wild populations on this species, this study was aimed to investigate the intraspecific variation of this important snowtrout. For this, two rivers and one lake in Kashmir Himalaya were sampled ...
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.
The theory of plane, elastic trusses is reconsidered from the viewpoint of the continuum theory of elastic media. A main difference between continuum and discrete theories is the following: In the continuous case all quantities are declared throughout the whole body, whereas in the discrete case each quantity has its own “carrier”. In a truss, for instance, displacements and applied forces are ...
