#### Abstract

With the increasingly enlarged process scale and the consequent requirement for large equipment, such as column, trusses ever widely applied in civil and building engineering have been introduced in petroleum chemical industry these years. Under this circumstance, truss structure optimization emerges as a study focus to balance safety, durability and economy. In this paper, an optimization example is introduced of a main truss beam system, namely centre, and its side beams in super-large column at high temperature. The main truss beam is optimized on three counts, that is, cross-section shape of the chord members, structure height and the pairs of the web members, while side beams are optimized by compromising among workability, stress, stiffness and weight.
