- Abstract
This paper presents the estimation of the carrying capacity of space structures with the use of the reliability theory and quantile algebra. Structures with rectangular meshes with every other blank mesh are shown to be economically competitive in relation to traditional full-wall and lattice roof coverings. On the basis of the structure reliability theory it is shown that connections of bars with nodes ought to have a greater carrying capacity than that of bars so that change of mechanisms of destruction from elastic-plastic to elastic-brittle does not occur. Attention is drawn to the fact that structures which are accompanied by geometric invariability resulting from articulated connections of bars with nodes are safer and have a smaller mass than structures whose geometric invariability depends on the spatial stiffness of the connections of bars with nodes. Attention is drawn to the additional advantages of selected economically competitive structures, namely: the possibility of support in any nodes of the structure, a smaller labour outlay in designing, execution and assembly and the ease of the provision of technological equipment in the structural space, including suspension of fire shields.
