Study On Structural Morphogenesis Technique In Restrictive Conditions Of Stress

In the real project, the demands for structure are different due to differentdemands for architecture, as a result, there are many restrictive conditions, likedisplacement and stress, for structure. The stress restrictive conditions alwaysrequire some bars have equal stress which is done by changing bar area in previousresearch and by changing truss shape in this paper. The matrix which we use aresingular or rectangle, so we use general inverse matrix. This paper will study thetruss in restrictive conditions of stress.The methods of this paper is elaborating mechanical equation, then usinggeneral inverse matrix in Fortran language to obtain optimal structure. The aim ofthis paper is to construct reasonable shape by making the number of equal stressbars as much as possible, that is, construct reasonable shape of truss in restrictiveconditions of stress. This paper discuss both plane truss and space truss in threekinds of conditions. The conditions are: except the supporting notes, all nodes canmove; the upper nodes can move; except the supporting notes, all under nodes canmove. In the specific projects, we can move random nodes using Fortran languageto obtain optimal structure.In discuss of plane truss we study the influencing factors of morphogenesis,the factors are: supporting conditions, stress restrictive conditions, load conditionsand the initial shape. We can use stress restrictive conditions and the initial shape toget various kinds of structures. This paper prove the possibility of morphopoiesis bythe use of many examples.The characteristics of this paper’s method are: the theory is easy, the evolutionspeed is fast and the parameter’s change is clear.
