Bitumen sand cushion energy-dissipating and shock-absorbing building

Abstract

The invention discloses a bitumen sand cushion energy-dissipating and shock-absorbing building, comprising a foundation, a ground ring beam fixedly arranged on the foundation, and an upper wall body built on the ground ring beam, wherein, the ground ring beam is composed of an upper ground ring beam and a lower ground ring beam, and a bitumen sand cushion is paved between the upper ground ring beam and the lower ground ring beam In the invention, by taking the bitumen sand cushion as an energy-dissipating and shock-absorbing structure and using the characteristic of a bitumen sand mixture having viscoelasticity and plastic deformation, an energy-dissipating and shock-absorbing layer is formed in a brickwork structure; and when a large earthquake is encountered, the bitumen sand cushion is subject to plastic shearing deformation, thereby achieving dissipation of earthquake energy transmitted from the foundation to an upper structure and making a shock-absorbing effect on the upper structure through weakening transmission of the earthquake energy to the upper structure. The bitumen sand cushion energy-dissipating and shock-absorbing building has the advantages of simple structure, being convenient to take materials, and being economical and effective; and meanwhile the building can facilitate building construction for villages and towns, improve earthquake-resistant capability of the brickwork structure, effectively relieve damage of the brickwork structure under the large earthquake and avoid collapse, lighten earthquake disasters and reduce casualties and property loss.

Description

technical field [0001] The invention relates to a shock-absorbing building, in particular to an energy-dissipating and shock-absorbing building with an asphalt sand cushion suitable for residents in villages and towns. Background technique [0002] my country is an earthquake-prone country. The Xingtai, Haicheng and Tangshan earthquakes in the 1960s and 1970s brought huge disasters to people's lives and properties. In the Wenchuan earthquake in 2008, buildings were severely damaged, especially in villages and towns, 80% to 90% of which were masonry structures. Because of the lack of anti-seismic fortifications or poor anti-seismic technical measures, a large number of houses were damaged and collapsed, and the earthquake damage was particularly serious , is the weak link of earthquake resistance. In 2010, another 7.1-magnitude earthquake occurred in Yushu, Qinghai, my country. The masonry structure was seriously damaged by the earthquake, and thousands of people were killed...

However, the traditional seismic isolation adopts base isolation based on rubber isolation bearings. This isolation system has mature technology and has been applied in actual engineering. However, due to its high cost, it is mostly used in relatively important building structures.

In addition, there are still a small number of pure friction sliding isolation systems, and the sliding iso
