Technical Field

Background

In recent years, building exterior decoration technology is continuously developed, the modern large public building structure form is more and more complex, and the building design has higher requirements on the permeability, aesthetic effect and uniqueness of the building curtain wall. Ultra-high performance concrete (UHPC) wallboard has the advantages of easy modeling, attractive appearance, good durability, long service life and the like, and is paid attention to popularization and application in the field of building curtain walls. The UHPC curtain wall technology is widely applied abroad and belongs to an emerging starting stage in China.

There are two types of UHPC curtain walls that are currently common: thinner and smaller in size, and thicker and larger in size, often at the same height as the building level. For the latter UHPC curtain wall, the connection mode between the UHPC curtain wall and the main structure is an important factor affecting the earthquake safety of the structure. The prior art generally adopts a rigid connection mode of the UHPC curtain wall and the main body structure. When the connection mode is adopted, the curtain wall and the main body structure are deformed together under the action of an earthquake, so that a large interaction exists. This interaction has a significant impact on the seismic performance and damage pattern of the main structure and subjects the connecting nodes to large internal forces, thus making the node design uneconomical. In engineering, designers often neglect the node internal force caused by the interaction and only consider the dead weight, wind load, out-of-plane earthquake action and other local loads born by the wallboard, so that serious earthquake damages such as node damage and wallboard falling can be caused, and great potential safety hazards are brought.
