A cytoskeleton of a living cell is framework structure that forms the cell shape and controls motion of the cell. It is constituted of three kinds of protein that are actin filament, microtubule and intermediate filament. Actin filament is contractible element with mechanical tension, and microtubule is stiffer element to support compression. Tensegrity is a concept of structure that is constructed by tensile elements and compression-supporting elements. Balance between the tension and compression of the tensegrity structure is in equilibrium, and it makes shape of the structure stable. The tensegrity structure is available for modeling of the cytoskeleton. In this study, stable shape problem of tensegrity structure was formulated mathematically, and a computer program to solve the problem was produced by using sequential quadratic programming. The program was applied to a six-strut tensegrity model, and its effectiveness was discussed.
