Characteristics and Selection of Steel Structure edited by Yi Fumin and Dong Wei, and the concept and principle of STS steel structure design; Portal frame design (including two-dimensional and three-dimensional design methods); Structural design of steel frame; Structural design of steel truss: structural design of steel bent: structural design of steel support. PKPMSTS Steel Structure Design-From Introduction to Mastery is characterized by unifying the extraction of steel structure model with the general process of STS steel structure design, explaining through typical engineering examples, analyzing the parameter setting skills of each operation module, with strong pertinence and clear thinking, and providing video demonstrations of actual operation of each steel structure design example in STS environment, which makes readers easier to understand and master.
