Design method of large span steel structure workshop

In the field of infrastructure construction, steel structure has created important opportunities for the development of steel structure workshop because of its advantages of simple construction and excellent performance. In addition, for the design of large-span steel structure workshop, in view of its complex structure, long construction cycle, so enhance the design of large-span steel structure difficulty. As a designer, in order to make the big span steel structure factory building design more reasonable and scientific, to ensure that its performance meets the demand of future use, in addition to the need to constantly improve their own designer, also should step up for large span steel structure factory building design research, to promote the development of steel structure workshop has important significance.

Since the appearance of structural design method, with the continuous passage of time, traditional structural design method has been unable to meet the requirements of the present stage, and performance-based structural design is becoming an important development direction of structural design in the future. Performance-based design refers to the use of engineering methods to make the performance of steel structures more consistent with established requirements. At the same time, in the performance-based design theory, designers can verify whether the performance of the designed steel structure meets the requirements of the project user through analysis, calculation, structure prediction and other methods, to ensure that the performance of the steel structure can meet the needs of the project user.

Generally speaking, if the component or structure has good ductility, its later deformation degree will be larger. Even if the yield or bearing capacity of the structure or component has been in the ultimate state, it can still absorb a certain degree of energy, which helps to delay the ductility failure time. Therefore, it is necessary for designers to control ductility when designing steel structures. In the process of designing long span steel structure, ductility design has become an important idea.
