Precautions for steel structure design and installation

Steel structure has been installed in many places now, but what should be paid attention to when the steel structure is installed and designed? Below, the HJSD steel structure manufacturer introduces what should be paid attention to when the steel structure is designed and installed.

 

According to the specific conditions of the project, the construction organization, construction facilities, component transportation, construction technical standards, general layout and other preparations shall be made before installation.The key points are to complete the assembly, welding and hoisting scheme, select hoisting machines and tools, train special types of work, arrange the schedule, prepare the construction organization design, etc.In addition to the fatigue strength calculation, the limit state design method based on probability theory should be used in the design of industrial and civil buildings and general structures, and the design expression of partial coefficient should be used for calculation.The safety level of general industrial and civil building steel structure can be taken as level II, and the safety level of special steel structure can be determined according to the specific situation.In the design of building structure, different safety levels should be adopted according to the possible consequences of structural damage.The bearing structure shall be designed according to the limit state of bearing capacity and the limit state of normal use.The limit state of steel structure engineering refers to the critical state that the structure or component can meet a certain functional requirement specified in the design, beyond which the structure or component will no longer meet the design requirements.The ultimate state of bearing capacity is the ultimate state when the structure or component reaches the maximum bearing capacity or reaches the deformation that is not suitable for continuous bearing.The serviceability limit state is the limit state when the structure or component reaches a specified limit value for normal use.When the structural members or connections are designed according to the bearing capacity limit state, the basic combination of load effect shall be considered, and the accidental combination of load effect shall be considered if necessary
