Sliding steel ball bearing hinge features a sliding ball joint bearing steel high-strength lightweight construction. Compared to steel and concrete structure, the quality of light movable hinge support, superior quality, and high strength movable hinge supports, with a vivid example to describe: For the same span, bear the same roof trusses load, a reinforced concrete roof truss Another is steel roof, the steel roof of their quality is only reinforced concrete roof trusses 1/3 ~ 1/4 What is movable hinge support, can fully be seen from this example of high-strength steel lightweight characteristics, based on this advantages for large-span steel used for construction. Sliding steel ball bearing hinge material uniformity, in line with assumed mechanics calculations. When we conduct mechanical calculations, we must first assume that this rigid material is homogeneous and isotropic, and in the steel mechanical calculations, without assuming that this condition, because the steel structure of the material itself to meet this performance, which is very commendable, the more obvious advantages. Slide ball bearing hinge hinge concrete detail of the requirements of reinforced concrete hinge detail design hinges on the use of good and bad effects of the concrete has a crucial influence movable hinge support price, all countries are conducting research on the hinge structure and distribution tendons made many designs and made good suggestions. By Fred Sinai (Freyssinet) hinges and hinge the same neck of concrete and steel instead of equal thickness, number of revolutions at different angles, shear and compressive ultimate strength were 2 × 10 repetitions pulse load test. [Slide ball bearing hinge] butyl rubber damping device using high damping ring, when the earthquake happened and force more than 20% each time the level of force, bearing liner concave convex set of words (the energy dissipation plate) and floor (lower energy dissipation plate) relative sliding by damping ring absorb energy. [Slide] ball bearing hinge static method static method that static equilibrium method is based on the force equilibrium equations to establish the conditions to have occurred after a slight deformation of the structure, and then solve for the critical load. Follow these basic assumptions in the establishment of equilibrium equations: 1) member is uniform bar. 2) pressure always acts along the axis of the original member. 3) material meets the Hooke's law, that stress and should become a linear relationship. 4) members meet the plane section assumption that the deformation of the front cross member in a flat plane section remains after deformation.
