Design method of long-span steel structure workshop
In the field of infrastructure construction, due to the advantages of simple construction and excellent performance, steel structures have created important opportunities for the development of steel structure workshops. In addition, for the design of long-span steel structure factory buildings, due to its complex structure and long construction period, the design difficulty of long-span steel structures has been increased. As a designer, in order to make the design of long-span steel structure workshop more reasonable and scientific, and ensure its performance meets the requirements of future use, in addition to continuously improving the designer’s own ability, it is also necessary to increase research efforts on the design of long-span steel structure workshop , to promote the development of steel structure workshop.
Performance design of long-span steel structure workshop
Since the emergence of structural design methods, with the passage of time, traditional structural design methods have been unable to meet the requirements of the current stage, and performance-based structural design is becoming an important development direction of future structural design. The so-called performance-based design refers to the use of engineering methods to make the performance of steel structures more inclined to the 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 methods such as analysis, calculation, and prediction of the structure, so as to ensure that the performance of the steel structure can meet the requirements of the project user. need.
Design ideas for long-span steel structure workshop
Generally speaking, if the component or structure has better ductility, the degree of its later deformation will be greater. Even if the yield or bearing capacity of the structure or component is already in the limit state, it can still absorb a certain degree of energy, which is Helps to delay the time of ductile failure. Therefore, when designing steel structures, it is necessary for designers to do a good job in ductility performance control. In the process of designing long-span steel structures, ductility design has also become an important idea in the design of long-span steel structures.
In ductility design, the following parameters need to be considered, namely: yield load, failure load, yield deformation and failure deformation. In addition, in order to ensure that the ductility design is more reasonable, the designer must first find a way to calculate the above ductility performance parameters, and analyze the yield load value and yield deformation index to ensure that the long-span steel structure can be used reliably and safely. In addition, in the ductility design, the designer should calculate the accurate proportional coefficient of bearing capacity to ensure that the long-span steel structure can reserve a certain amount of bearing capacity before structural damage occurs. Finally, in the process of ductility design, designers should accurately and reasonably determine the deformation ratio coefficient, so as to ensure that the long-span steel structure itself can have a certain deformation capacity reserve before structural damage occurs. In short, for the performance design of steel structures based on ductility, designers should consider the calculation and analysis of geometric nonlinearity and material nonlinearity of the system, so as to obtain performance parameters such as yield load and failure load of steel structures, and based on this, propose a solution that meets national standards. Required security design performance control indicators.
