Background
The rammed earth building plays a great role in the traditional building form of China, has a wide distribution range almost throughout the whole country and is variable in form, and abundant substances and cultural heritages are left for the traditional residential form. The use history of the rammed earth building is far from long, and the rammed earth building is the most easily realized building form before people master the mature tile firing technology. In addition, the rammed earth building is made of local materials, green and environment-friendly, and is favored in rural areas with underdeveloped economy and abundant manpower resources. Nowadays, a large number of classical villages are left, which show the refulgence of rammed earth buildings.
Traditional rammed earth constructions are mainly composed of three parts: foundations (rammed earth rammed or masonry), rammed earth walls and roofs. The rammed earth wall is the most important component of the rammed earth building, not only is the comfortable living performance of the rammed earth building built, but also the unique simple air quality and the thick and elegant natural aesthetic feeling of the rammed earth building are given, and the rammed earth wall is the characteristic of the building. In addition, the rammed earth wall is a load-bearing member of a whole building, and the mechanical property of the rammed earth wall is directly related to the whole safety of the structure. However, the construction process and the material characteristics of the rammed earth wall determine that the wall body naturally has the defects of insufficient strength and integrity, which becomes an important factor threatening the life and property safety of residents for rammed earth buildings distributed in vast earthquake areas in China. The occurrence of the Sinkiang Bachu earthquake, the Yunnan Dayao earthquake, the Jiangxi Jiujiang earthquake and the like in recent years all show the defect of insufficient earthquake resistance of the rammed earth wall.
The poor seismic performance of the rammed earth wall is mainly caused by the reasons of the self weight of the wall body, insufficient shear strength and tensile strength, poor plane external rigidity and the like. Under the action of earthquake, the intensity of the rammed earth wall is not enough to resist the acting force generated by the earthquake, and the serious result that the wall collapses is caused. In addition, the construction of the rammed earth wall is mainly carried out by local craftsmen by virtue of experience, corresponding anti-seismic concept and cognitive level are lacked, certain randomness exists in the construction process, and potential safety hazards are buried in weak parts of the rammed earth wall. Some existing measures for adding constructional columns and ring beams find that the existing measures cannot generate a good constraint effect on a wall body in the investigation after earthquake, and the phenomenon that the wall is inverted and the column stands often occurs in the earthquake.
The rammed earth buildings widely distributed in China are widely located on earthquake zones, and the method has important significance for improving the living safety of users and avoiding unnecessary life and property loss by adopting a feasible technical means to improve the earthquake resistance of the rammed earth buildings.
