Design And Study On The Heavy Steel Structure Of Portal Frame Plant

Heavy duty steel plant is widely used in modern industrial production, and its advantages are obvious. Heavy steel structure factory building structure should be designed to meet the technical requirements under the premise, so that the overall structure or local member under service loads safe and secure work and meets the project requirements. Therefore, the structure is designed to solve the fundamental problem with the structure of the select an optimal balance between reliability and economic efficiency, the lowest investment to achieve the most appropriate structural safety, serviceability and durability requirements. According to the designers have years of design experience, design is reflected not only in the quality of the heavy steel structure factory building structural safety and serviceability, steel consumption is also an important indicator. On the heavy steel structure factory building in the lattice column is good deformation and mechanical properties, and can take a large extent saving steel consumption.Layout structure is one important piece of early design, feasibility studies, preliminary design stage on project investment budget, bidding work plays an important role in guiding. Through the availability of different steel plant steel quantity variation can greatly reduce the workload of the trial. Master the heavy steel structure factory building in different economic indicators under the column space is of great significance.In this paper combines engineering instance, through software established structure calculation model, to describe heavy steel plant in calculation process in the of parameter selected, load taken; Specific described of heavy steel plant of structure layout, design principles and the actual application in the of specific method and note matters; To show support system of calculation method and layout principles; achieved has on single layer steel plant of frame structure, crane beam, support system and enclosure structure in different column space layout of calculation and analysis; Calculation and analysis of seismic intensity effect on the steel plant under different column spacing. Under the different column form, the weight of each component steel and the overall is calculated, studied and compared, so more economical column space obtained. All of that can be used to the preliminary design scheme of similar projects for the future reference.
