Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0018] As shown in the accompanying drawings, the present invention is a replaceable coupling beam with enhanced energy consumption, which consists of a non-yielding section 1 and a replaceable section, the replaceable section is connected in parallel by a lead rubber damper 2 and two U-shaped steel plates 3 Composition, two U-shaped steel plates 3 are symmetrically arranged on the upper side and the lower side of the lead rubber damper 2 and fixed together with the end plate of the lead rubber damper 2 .

[0019] The U-shaped steel plate 3 is made of low yield point steel.

[0020] The U-shaped steel plate 3 does not yield during a small earthquake, but yields to dissipate the input energy of the earthquake during a moderate or large earthquake.

[0021] The replaceable section and the non-yielding section 1 are connected together by an embedded part 4 .

Abstract

The invention discloses an energy dissipation enhanced-type replaceable coupling beam and belongs to the field of seismic resistance of high-rise building structures. The energy dissipation enhanced-type replaceable coupling beam is composed of a non-yielding section and a replaceable section. The replaceable section is formed by connecting a lead-core rubber damper and two U-type steel plates in parallel, and the two U-type steel plates are symmetrically arranged on the upper side and the lower side of the lead-core rubber damper and fixedly connected with an end plate of the lead-core rubber damper. During a small earthquake, the U-type steel plates do not yield, and during a medium earthquake or major earthquake, input energy of the earthquake is dissipated by the U-type steel plates and the lead-core rubber damper; meanwhile, the replaceable section can be easily repaired and replaced after the earthquake if damaged; the energy dissipation enhanced-type replaceable coupling beam has high popularization and application value.

Description

technical field [0001] The invention relates to the anti-seismic field of high-rise building structures, in particular to a replaceable connecting beam with enhanced energy consumption. Background technique [0002] At present, most of the existing replaceable connecting beams dissipate energy through the yielding of the replaceable sections, but the disadvantages of most of the replaceable sections are that their energy dissipation capacity and deformation capacity are poor, and the replaceable sections cannot play an effective role in large earthquakes. The energy dissipation effect, which leads to the general seismic performance of the replaceable coupling beam. [0003] Therefore, it is urgent and particularly meaningful to develop a coupling beam that has strong energy dissipation capacity and deformation capacity, and can be easily repaired and replaced after an earthquake. Contents of the invention [0004] In order to overcome the shortcomings of the existing repl...
