Multi-disaster defense structure

Abstract

The invention discloses a multi-disaster defense structure comprising prefabricated frame columns, prefabricated frame beams, energy consumption angle steel connectors, shear transferring plates and multi-disaster defense steel tie bars, wherein the energy consumption angle steel connectors, the shear transferring plates and the multi-disaster defense steel tie bars are used for connecting the prefabricated frame columns and the prefabricated frame beams. The multi-disaster defense steel tie bars are matched with the energy consumption angle steel connectors to achieve self-resetting and energy consumption of the structure under an earthquake. The shear transferring plates are matched with the multi-disaster defense steel tie bars to meet the requirements of continuous collapse preventing bearing capacity and large deformation of the frame structure. Therefore, destruction of the prefabricated structure when the earthquake and continuous collapse occur can be effectively reduced, a prefabricated frame can conduct self-resetting under the effect of the earthquake and be repaired only by replacing the energy consumption angle steel connectors, anti-seismic and anti-continuous-collapse performance and repairable ability of the prefabricated structure are greatly improved, and the multi-disaster defense structure has important significance for reducing the loss brought by disasters.

Description

technical field [0001] The invention relates to the technical field of civil structure engineering, in particular to a multi-disaster prevention structure. Background technique [0002] In recent years, with the rapid and stable development of my country's economy and people's increasing attention to energy conservation and environmental protection, industrialized construction methods are more cost-effective than traditional cast-in-place construction techniques when building houses. Therefore, construction industrialization is gradually becoming the future A major direction for the development of my country's construction industry. [0003] Among them, the key technical requirement of the prefabricated structure is to ensure that the prefabricated structure has sufficient rigidity, ductility and bearing capacity. However, building structures may face threats from different hazards during their entire life cycle. Improving the multi-hazard defense capability of structures is...

Problems solved by technology

For example, the Wenchuan Earthquake Damage Survey shows that the repair work of frame structures after the earthquake is heavy and expensive; another example is the most typical case of continuous collapse of frame structures, that is, the Oklahoma
