This textbook introduced the design method of several kinds of buildings steel structures, compiled based on current codes Standard of steel structure design(GB 50017-2017)and Technical code for steel structure of light-weight building with gabled frames (GB 51022-2015) and so on. This textbook introduced the design method of several steel structures including the platform steel structures, the light-weight steel portal frames (gabled frames), heavy industrial buildings (including the angle steel roof truss and the crane beam), large-span roof structures, high-rise building structures, and tubular steel structures with unstiffened connections. By introducing the basic design provisions and principles of common Chinese codes related to steel structures, the textbook enabled international students and Chinese students in bilingual programs to understand and master the general requirements and methods of Chinese steel structure design method to the greatest extent.
This book can be used as the professional basic course material of civil engineering, and can also be used as a reference book for those who are engaged in overseas steel structure engineering design and for construction engineers and technicians.
