"In the reality, a concept of \u201Ebend less shape design\u201C is some sort of utopian vision - bend less state is deterministically given for a certain shape of the structure and the actual load. Real load acting on the structure stochastically. If the structures cannot continuously modify the shape given to counteract the current load, bend less condition cannot be guaranteed at all times. But it is possible to estimate the long-term non-variable component of loads and adjust the shape of the centerline in order to minimize the bending effects. Practical applications and theoretical calculations show that an appropriate choice of the shape design can significantly reduce bending effect from unchangeable load and move closer to the ideal membrane structure acting. As a goal of the project the simple computational tool was created for solving 2D beam model in iterative manner while settling shape of vaults and arches to minimize bending effects of operating model loads. User must define a model load on vault with their horizontal and vertical effects. The tool is primarily intended to compensate the shape buried and non-buried arches, arch structures loaded by the single forces and search driven membrane shape. Output from the program is the field of source commands for AutoCAD that render the upper and lower surface of the structure and the axis in the local coordinate system." . "SECON-CSSE" . . .
