This thesis deals with the development of a tool intended for automatic optimization of point support distribution for plate and shell structures. In an architectural context point supported plate or shell constellations are typically represented by doubly-spanning, in situ concrete systems carried by columns. Correspondingly, the tool is developed with in situ concrete systems in mind. However, the tool appliance is not restricted to concrete as material choice, although it is designed for a doubly-spanned load carrying structure consisting of an isotropic material.
