The traditional structural earthquake-resistant design is mainly used for resisting earthquake action according to the strength, rigidity and ductility of a structure, and a large number of earthquake cases show that after a large earthquake, a structural body is damaged and destroyed to a certain degree, and serious people can have irrecoverable results. The energy dissipation device adopted by the structural energy dissipation and shock absorption design can be composed of energy dissipaters, bracing, walls, beams and other supporting members, the current common displacement-related energy dissipaters are divided into a shear yielding type and an axial yielding type according to the yielding form, and due to the structural particularity, the current common energy dissipaters are high in manufacturing cost, so that the application of the structural energy dissipation and shock absorption technology is limited to a certain extent. Therefore, a new 'engineering structure damping control' system is generated, and a plurality of control devices are arranged in the structure, and when the earthquake acts, the control devices passively or actively apply a group of control forces to slow down the structure vibration and reduce the structure deformation.

Detailed Description

In this embodiment, referring to fig. 1, fig. 2, and fig. 3, the novel energy dissipation wall shock absorption structure includes a lower shear wall 3 and an upper shear wall 5 respectively disposed in a space between a frame beam 1 on the present floor and a frame beam 2 on the upper floor, where the upper shear wall 5 is opposite to the lower shear wall 3 in the up-down direction and is spaced apart from the lower shear wall 3 by a distance, the lower shear wall 3 is fixedly connected to the lower frame beam 1, and the upper shear wall 5 is fixedly connected to the upper frame beam 2; an energy dissipation key 6 (with the model of RT-600) is arranged between the upper shear wall 5 and the lower shear wall 3, and the upper end and the lower end of the energy dissipation key 6 are respectively connected and fixed with the upper shear wall 5 and the lower shear wall 3.

The lower shear wall 3 and the top surface of the frame beam 1 at the layer are integrally cast to form a tight connection structure during construction; the upper shear wall 5 and the bottom surface of the upper-layer frame beam 2 form a tight connection structure through integral pouring during construction.

And the upper end and the lower end of the energy dissipation key 6 are respectively connected and fixed with the bottom end of the upper shear wall 5 and the top end of the lower shear wall 3 through bolts.

The energy dissipation steel plate of the energy dissipation 6 key is made of BLY160 mild steel, the yield force of each energy dissipation key 6 is not lower than 600kN, the limit force is not lower than 1200kN, and one energy dissipation steel plate can be used independently or more than two energy dissipation steel plates can be used in a combined mode.

The main mechanical parameters of the RT-600 energy dissipation bond are as follows:

the upper shear wall 5 and the lower shear wall 3 are the same in size, are both walls made of reinforced concrete with the C35 standard, are 400mm thick, 1500mm long and 1400mm high, and have a distance of 500mm between the upper shear wall 5 and the lower shear wall 3.

Connecting steel plates are respectively embedded in the upper shear wall 5 and the lower shear wall 3, and the connecting steel plates are respectively connected with the upper-layer frame beam 2 and the local-layer frame beam 1.

Wherein, the two ends of the frame beam 1 and the upper frame beam 2 are respectively connected with the upright frame column 4.

The bending bearing capacity of the lower shear wall 3 and the upper shear wall 5 is not less than 2666kN.m, and the shearing bearing capacity is not less than 2690 kN.

The high-area floors greatly contribute to bending deformation (geometric deformation), the energy dissipation wall is difficult to play a good energy dissipation effect in a relative middle area of the area through stress mechanism analysis, and the efficiency is low. The design is used for reducing the fixed point displacement of the structure under the major earthquake in the X direction of the high region by arranging 4 energy dissipation walls on each layer, and the lateral rigidity and the deformability of the structure under the major earthquake are improved. As shown in fig. 4, under the action of natural wave 1, the X-direction displacement angle of the high region of the elastoplastic model is obviously reduced (from 1/119 to 1/149) after the modification, and the energy dissipation wall effectively limits the adverse effect of high vibration type response on the structure, and the necessity of arranging a certain amount of energy dissipation wall in the high region of the structure is also proved.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the scope of the invention, i.e. the present invention is intended to cover all equivalent variations and modifications within the scope of the present invention.
