Anwendungsbeispiele zur Optimierung verformungsempfindlicher Tragwerke

Application studies to optimize deformation sensitive structures.

Many building structures are designed in such a way that the deflection in a critical point of the structure is reduced as much as possible (e. g. the middle span of a bridge or the top level of a high rise building). This often requires a lot of material. In addition optimizing these kinds of structures by hand is quite difficult and time consuming. This article demonstrates the practical usage of an optimization method (called MVM), which allows an engineer to redistribute the material within a geometrically given structure in such a way that the deflection in a critical point is reduced as much as possible. The demonstrated case studies are a steel truss bridge over four spans and a steel roof structure for a bus station.
