Abstract
The invention belongs to the field of vibration control of building structures, in particular to a double-layer combined energy-consuming structure. The double-layer combined energy-consuming structure comprises an outer-ring energy-consuming steel pipe, energy-consuming ribs, built-in circular holes, an inner-ring energy-consuming steel pipe, connecting plates, connecting plate screw holes, leaddot holes, external energy-consuming washers, lead dots, end energy-consuming steel pipes, an energy-consuming filling material, wave peak energy-consuming steel plates, wave trough energy-consuming steel plates, end energy-consuming steel plates, shape memory alloy reset springs, end energy-consuming washers and internal energy-consuming washers. The double-layer combined energy-consuming structure has the advantages that the design of the double-layer structure combined internally and externally is adopted, the overall structure has a reasonable initial stiffness, the supporting and bearingcapacity of a building can be increased when the structure is used under a normal condition, the structure has good seismic performance, ductility and hysteretic energy consumption performance in theevent of an earthquake, so that damping and energy consumption can be achieved maximally, and the design of the double-layer structure combined internally and externally makes the energy consumption of the structure more evenly dispersed, so that the energy consumption is more sufficient.
Description
technical field [0001] The invention belongs to the field of vibration control of building structures, in particular to a double-layer combined energy-consuming structure. Background technique [0002] Earthquake disasters are sudden and devastating, which seriously threaten the safety of human life and property. Nearly a thousand destructive earthquakes occur every year in the world, and a major earthquake can cause hundreds of billions of dollars in economic losses, resulting in hundreds of thousands of deaths or serious injuries. my country is located in the two most active seismic belts in the world, and is one of the countries that suffered the most serious earthquake disasters. The casualties caused by the earthquake rank first in the world, and the economic loss is also very huge. The massive destruction and collapse of buildings in earthquakes is the direct cause of earthquake disasters. When an earthquake occurs, ground vibrations cause the seismic response of the...
