The optimum form which corresponding to stress, changes the cross section of the edition condition space framework roof

(57) Abstract Objective The part component in the lithography space framework structureUnevenness, unnaturalness is cancelled. Constitution In structure of necessary lithography space framework structure, tare weight,Operation various outer forces, it is proportionate to the distribution of the axial force of each single piece of composite member which it occursWith doing, reconstructs the truss forming of the section the axis of each single piece of composite memberEqualization of power is assured, becomes simultaneously equalization of material diameter possible.To cancel the part unnaturalness of the truss with this, the natureSo, the space framework construction by optimum form is implemented.
