The article describes the design theory method

design points

and design process of the prefabricated steel frame structure

then analyzes engineering application and economic benefits of prefabricated steel frame structure.it is concluded that the design theory method of prefabricated steel frame structure has strong direction

operability and practical guiding significance

and prefabricated steel frame structure layout is more flexible

the construction period is shorter

the construction quality is better

it is more in line with the requirements of "green building

energy saving and environmental protection"

and the comprehensive benefit is better.
