Abstract
The methodology of determining the optimal geometric shape of the lattice in the combined arch system was developed under conditions of tensile capacity of all elements of the flexible lattice and the minimum material consumption of the structure for circular plan buildings with a central pillar. Circular plan buildings with a central pillar rigidly attached to the basement can be used for bus parks, trolleybus depots, markets, etc. The roof shape meets the requirement for a convex roof covering and creates favorable conditions by reducing atmospheric impacts. Due to the horizontal component of the support reaction of the arch system, the external inclined pillar can be used to create the necessary value of pre-stressing, including self-regulated pre-stressing, i.e. when the snow load rises the value of movement of the support part of the arch system and the inclination angle of the pillar increase which leads to the increase of tension in the lattice elements. In this case, the compressed upper belt of the arch system is unloaded. At this stage of the study, the optimal shape of the lattice is supposed to be determined only by the geometric shape of the lattice itself, without pre-stressing of its elements.
