Background technique

With the rapid development of my country's rural economy, the construction of villages and towns has set off another round of upsurge after the mid-1980s. However, through the current booming scene of village and town construction, it is not difficult to see that many village and town construction projects in many places still have problems such as many hidden dangers in quality, short service life of housing, and quality accidents occur from time to time. After investigation, it is found that ring beams and structural columns are basically not installed in the current village and town buildings. Even if there are, the cross-sectional size reinforcement is not based on the basis, which is very random and cannot achieve the actual effect that should be achieved. Most floor slabs use prefabricated slabs. When there are no ring beams, the prefabricated slabs are placed directly on the wall, and the penetration into the wall is too small, resulting in poor integrity of the house. Therefore, in previous earthquakes, village and town buildings were often the most severely affected. the

The current "Code for Seismic Design of Buildings" has made clear regulations on the setting of ring beams and structural columns of masonry structures. Due to the limitations of economic development, it is unrealistic to put forward requirements for houses in villages and towns in my country in full compliance with the Code for Seismic Design of Buildings. Therefore, it is imminent to study technical measures that are economically reasonable and acceptable to the masses to solve the problems of poor integrity and weak seismic performance of houses in villages and towns. the
