Please tell me the difference between adobe wall and rammed earth wall?

1, the characteristics of different

Rammed earth wall is built with rammed earth method; and adobe wall is a house with mud for the wall, the wall inside and outside of the materials used are mud, there are two main ways to become a wall: one is a good foot of the wall (generally stone for the foot of the wall) with a wooden mold, placed on it, into the mud mold manually tamped into a wall in sections and layers. The second is the handmade earth brick, (mostly refers to unfired earth bricks) wall into the house.

2, different performance

In the monotonous load, plain earth wall, grass earth wall bearing capacity is similar, while the bearing capacity of gray earth wall is lower. Under repeated loading, the three kinds of wall skeleton curve change rule is similar, and the size of the ultimate bearing capacity is also similar.

Compared with the ultimate load under monotonic loading, the ultimate load under repeated loading is slightly reduced, about 80% ~ 85% of the ultimate load under monotonic loading. Under monotonic loading or repeated loading, the ductility coefficients of plain earth wall, gray earth wall and straw earth wall are slightly different from each other, and the ductility coefficients of gray earth wall and straw earth wall are slightly lower.

The ultimate stiffness of the gray earth wall is greater than that of the plain earth wall and the straw earth wall in the same working condition. In terms of the energy dissipation capacity of the hysteresis curve, the energy dissipation capacity of the plain and straw earth walls is better, and the energy dissipation capacity of the gray earth wall is worse;

And the adobe house structure is easy to be damaged in earthquakes, and the reasons for this are roughly the lack of strength of the members, the weak connection of the nodes, and the poor stability of the structural system, and so on.

Expanded information:

Tang Chang'an's imperial city and palace walls were rammed earth walls, and the city's liwang were also separated with Rammed earth wall separation, to the Northern Song Dynasty rammed earth technology and progress. The Northern Song Dynasty craftsman Li commandments edited the book "building method" systematically summarizes the achievements of the rammed earth version of the building technology at that time.

The provisions of the "system of building walls, each wall is three feet thick, then nine feet high, and its diagonal collection, than the thickness of half; if the height increases by three feet, then the thickness of the increase of one foot, the reduction is also the same". Fujian Tulou put the traditional Chinese rammed earth construction technology to the peak.

Ancient buildings, city walls and tombs use a lot of rammed earth walls, rammed earth walls in archaeology has an important significance.

Taosi ancient observatory foundation site rammed earth wall, Shanxi Linfen South Xiangfen County found between about 2600 BC to 2100 BC Taosi site. 2003, in the Taosi site was found in a large building foundation address: ancient observatory foundation site.
