Description

Method for improving earthquake resistance of building masonry
Technical Field

Background
The masonry structure is the most common structural form in the existing buildings, but as a large number of existing buildings are long-term in construction and the strength of masonry mortar is low, the seismic performance of the masonry structure can not meet the requirements of the existing specifications. The traditional seismic strengthening method for the masonry structure comprises a double (single) face reinforcing mesh method, additionally arranged pull rods, constructional columns and the like. Existing buildings that are typically in use do not want construction teams to enter the room (or enter the room less) in view of personal privacy and damage to the original installation. The use of the high-ductility concrete and the high-ductility mortar provides a new idea for seismic reinforcement of masonry structures. The novel material is added with PVA fiber besides common concrete components such as cement, sand, fly ash, water reducing agent, water and the like, so that the ductility of the material is obviously improved, and the novel material has stronger energy dissipation and shock absorption effects when an earthquake occurs. In a low-rise (single-story or double-story) masonry structure building, a good earthquake-resistant reinforcing effect can be achieved by using an outer wall ductile concrete plastering method. However, the inventor finds that for a multi-layer masonry structure, with the increase of earthquake effect, the requirement of earthquake resistance cannot be met by only plastering the outer wall with high-ductility mortar, and meanwhile, in consideration of reducing disturbance to residents, other earthquake-resistant measures must be adopted to achieve the aim of earthquake resistance.
