Abstract：This project is a multi-layer light industry plants, taking into account the light weight of steel structures, seismic performance,speed of construction, and high degree of mechanization,adopting the steel frame construction system. Its advantages are: to provide greater interior space, building layout flexibility to adapt to various types of use function; generally prefabricated steel beams and columns at the factory, transported to the construction site and then assembled into a whole frame connection; simple structure, member easily standardized and stereotyped, for much of the construction layers, the framework is a more economical, widely used structure system.

This project is 5-story steel frame factory, seismic intensity of 7 degrees, site category II class design earthquake grouped into the first group. Calculated transverse frame bearing structure analysis, specific contents include: structure of the program and primaries sectional dimension; structural calculation diagram and load calculation; structural internal force analysis under horizontal load; structure force analysis under vertical loads internal; load effect and internal force combination; column section checking and node design; combination floor and staircase design; basic design; drawing construction plans; and computer-aided design. During cross-section seismic design, column by eccentric ensure ductile frame to content the design principle of "strong shear weak bending, strong column weak beam, strong joint weak member".

Keywords: structural design, steel frame, multi-storey factory
