On the way steel reinforcement

　　On the way steel reinforcement
The main way to Hainan Steel steel reinforcement are: to reduce the load, change the structure of computation graph, increasing the original structure member section and cohesion strength, prevent crack development and other. When a mature experience, or may choose other reinforcement approach. 1, changes in the structure of the graphics computation graph changes structural calculation refers to the choice of reinforcing way to spread the load status changes, load path, node properties and boundary conditions, the addition of an additional lever and support, prestressed, consider the space to work on the structure and other measures reinforcement approach; reinforcing way alter the general structure calculation graph: The structure of the following approaches can be used to increase the stiffness of the structure or member reinforcement: A, increase support structure constituting the spatial structure and press space checking; B, plus increase the structural support provided rigidity, or adjust the natural frequencies of the structure in order to enhance the structural capacity and improve dynamic characteristics; C, additional support or auxiliary rods so that the structure of the slenderness ratio reduction to improve its stability; D, the focus in the bent structure strengthen the stiffness of a column by column, so that they bear most of the horizontal force to relieve other column column load; E, set moderately tensioned cable or rod to strengthen stiffness of the structure of the tower and other structures. Bending the lever on the way to access the following changes to its cross-sectional internal force reinforcement: A, change load distribution, for example, a gathering will load into a plurality of sets load; B, end support change, for example change is hinged Just knot; C, an increase in the middle seat or simply supported ends cohesion become successively structure; D, a series of structural adjustment of seat position; E, the structure becomes strut-type structure; F, prestressed. May take the following changes to the truss member forces its way reinforcement: A, added to strut brace truss structure changed; B, plus set prestressed lever. 2, increase the cross section of the reinforcing member selection when increasing section reinforcing steel members, selected cross-section in the form should be conducive to strengthening the technical requirements and consider the existing deficiencies and condition of injury. 3, convergence and reinforcement of reinforcing steel Cohesion Cohesion way, choose the welds, rivets, bolts and high-strength bolts general convergence of approach should be based on the structure needs strengthening reasons, intent, force status, structure and construction conditions and consider ways to determine the structure of the original link. Steel reinforcement is generally better to use the weld convergence, friction-type high convergence, there may also be chosen according to when welds and friction-type high mixing convergence. Weld was elected with a link, you should choose assessed and approved welding technology convergence materials. 4, the amendment and the reinforcement structure cracks because repeated load effects and material selection, construction, manufacturing, construction and installation of improper produced having the tendency to expand or brittle fracture crack damage, should seek to amend. Before amendment, must analyze the seriousness of the cause of cracks and their impact, targeted to improve the structure of the actual work or take reinforcement approach should not be selected for amendments reinforcement member, should be withdrawn to be replaced.
