Example Embodiment

[0026] The present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0027] Such as Figure 1~7 As shown, the present invention proposes a fabricated mild steel-friction composite damper, including a first connecting plate 1, a second connecting plate 2, a first friction plate 3, a second friction plate 4, a high-strength bolt 5 and a mild steel Stick 6.

[0028] The first connecting plate 1 is composed of a bottom plate 7 and a web 8. There is a stiffening rib 9 between the bottom plate and the web plate to increase the strength. The bottom plate is provided with bottom plate bolt holes 16 through which high-strength bolts pass through the bottom plate bolt holes 16 and Column H is fixed; both sides of the web 8 are sandblasted; the second connecting plate 2 has the same shape and size as the first connecting plate, and is fixed to the beam I through the bolt holes 16 of the bottom plate by high-strength bolts;

Abstract

The invention provides an assembly soft steel compound friction damper and an assembly method thereof. The assembly soft steel compound friction damper comprises a first connection plate connected with a longitudinal building member and a second connecting plate connected with a horizontal building member, wherein a first friction plate is fixedly connected to the first connection plate through high strength bolts, a second friction plate is fixedly connected to the second connection plate through high strength bolts, the first friction plate is fixedly connected with the second fraction platethrough high strength bolts, soft steel bars are arranged on the connection parts between the first connection plate and the first friction plate, between the second connection plate and the second friction plate and between the first friction plate and the second friction plate in a penetrating mode. According to the assembly soft steel compound friction damper, when relative deformation is occurred the joints of beam columns, the fraction plates are enabled to slide relatively, and a friction energy consumption mechanism begins to perform functions; and when the deformation is increased toa certain extent, the soft steel bars begin to consume energy, the organic combination of two different energy consumption mechanisms is achieved, all-bolt assembly is adopted by the assembly soft steel compound friction damper, the manufacturing cost is low, installation and disassembling are convenient, and application range is wider.

Description

technical field [0001] The invention relates to an assembled mild steel friction composite damper and an assembly method thereof. Background technique [0002] The mild steel damper utilizes the low yield point, long plastic section and good hysteresis characteristics of mild steel to achieve the purpose of energy dissipation and shock absorption of engineering structures. In 1972, kelly and other scholars proposed the mild steel damper and applied it to the field of engineering energy dissipation and shock absorption technology, and confirmed that the mild steel damper has a full hysteretic curve and can effectively weaken the earthquake effect. Since then, there have been more and more studies on mild steel dampers at home and abroad, and various forms of mild steel dampers have been proposed, and the performance stability of mild steel dampers has been demonstrated through experiments. The fatigue performance is good, but there is an energy dissipation mechanism. Disadva...
