The civil engineers have a responsibility to society to offer best possible solutions in order to design more sustainable buildings. A way to incorporate sustainability concepts by the structural engineers is the attempt to reduce both material consumption requirements and energy use during all phases of design. In a sustainability focused society, the amount of the matter resulted from a structural design according to the norms, may be of key importance. Nowadays, structural engineers are trained to design for me...

From a structural optimization point of view, the design of steel lattice towers begins with choosing from various alternatives to develop the geometry of the incorporated trusses. The biggest challenge is to find optimal geometry based on experience. In contrast to some structures that are generally intuitive to construct, (e.g. common buildings structures), the same design for the tower structures is frequently built for several times. Thus, cost savings and performance improvements obtained by structural optimi...
