Abstract The project is a light portal frame,which is a single span and double slope form。 A crane with a weight of 10t is set up within the span。 The span is 30m long, vertical structure size is 96m, column is 6m。 According to the Code for Design of Steel Structure, and Technical Specification for Steel Structure of Light-Weight Buildings with Gabled Frames standard, considering the design data for a variety of conditions, choose the light steel structure of light weight, high strength, construction period is short and economy and convenient。
The composition of the design is mainly composed of two blocks, the first block is the architectural design, and the other is the structural design。The architectural design consists of architectural plane column net design, facade design, building profile design, wall design and some other ground practices, ramp practices and steel plant fire prevention measures, etc。。 Next is the structural design。 Structural design mainly consists of main frame design, sub component design and foundation design。 Main frame design first choosing PKPM software to model selection, to meet the initial requirements through the combination of internal forces obtained the most detrimental to the internal force of the member selection for checking, carries on the design to the node and the column。 Component selection according to the front of the main frame are designed to be adaptive selection, need to check the roof panel, purlin, walls, beams, braces, brackets and crane beam component to satisfy the corresponding conditions。 Based on the independent foundation of the design selection column, the load capacity of the upper wall column is calculated and the calculation of the bearing capacity is calculated。
The last part is the drawings: building plan, elevation, section, rigid frame construction drawing, crane beam layout figure, purlin and support arrangement diagram and the basic layout and so on。 The design of strict compliance with the relevant professional design requirements, reference to the latest national industry standards, and strive to achieve scientific and correct。
