Abstract

The invention discloses a fabricated circular steel tube energy-dissipating support which comprises a support body, an end plate, a bolt, a nut, two energy-dissipating components, a baffle, a connecting plate and a stiffening rib. The two energy-dissipating components are detachably arranged at the two ends of the support body correspondingly. According to the fabricated circular steel tube energy-dissipating support, the problems that as for an existing structure, an inner core dissipates energy, deforms untimely and consequently may lose effect untimely in an earthquake, and the replacing and maintaining cost is high can be solved.

Description

technical field [0001] The invention belongs to the field of building shock absorption, and relates to an assembled energy-dissipating support. Background technique [0002] my country is an earthquake-prone country, and the occurrence of earthquakes has brought huge losses to people's lives, property and local economy. [0003] The mechanical characteristics of low yield point steel are low yield strength, small yield strain, stable strength and strong deformation ability. The low-yield point steel energy dissipator utilizes the good plastic deformation capacity of low-yield point steel to produce hysteretic deformation during earthquake action to consume the vibration energy input into the structure and effectively attenuate the seismic response of the structure. The low-yield-point steel used in the field of anti-seismic buildings in my country has developed three grades with yield strengths of 100MPa, 160MPa, and 225MPa. This provides the necessary material basis for m...
