Research On The Economic Analysis Of Steel Staggered Truss

The steel staggered truss system is a kind of economic, practical and efficient system of the new structure. It has a wide application prospective using in steel structure of housing and student hostel. Truss is the major part of staggered truss system. It has important value to study on this structure.In this paper, By analyzing the current planning on steel structure of housing and student hostel, combined with load bearing behavior of staggered truss system, including structural models of the select and loading, trusses internal force calculation, the shape of section and the design of section, and the number of truss internodes, Structural models are built on the basis of housing and student hostel. Using ANSYS to calculate internal force and design the section, gained the used steel quantity.The truss structure with the use of quantities of steel to every truss the chord and belly and columns of steel framework for the amount of truss structure, therefore always use steel amount of proportion. the column space, floors, number of truss internodes, among the length of truss structure with a steel of the impact and influence factors in quantitative analysis.Use of artificial neural networks, and use of quantities of steel of the column span, and number, the floor location, number of truss internodes, neural network model, artificial Through the parameters of change and train, the forecast results better BP network model. the model can for designers to design a truss by contrast, in the preliminary design can provide more accurate trusses used steel for project investment.Analyzed staggered truss production and installation of materials and labor, and durations, the effective size and material, refurbishment, building energy conservation and environmental protection with regard to the cost of truss. Truss structure of the economic and social benefit.
