Structural design key points of post-tensioned prestressed frame and steel secondary beam combined prefabricated logistics warehouse
A post-tensioned prestressed frame and steel secondary beam combined prefabricated logistics warehouse structure system was proposed.Based on a logistics park project in Langfang,Hebei province,the structural layout of the system was introduced.The design points of beam-column joints,prestressed tension joints,main and secondary beam joints,and composite steel secondary beams were also introduced,and a complete set of technical solutions was provided.Comparing the construction period and cost of the system with the cast-in-place concrete frame structure,it is concluded that the system can reduce the construction period and reduce the cost.
