It is an objective fact that rural dwellings are generally of poor quality and basically do not have seismic performance. It is a newly built house, because it is greedy for convenience, saving trouble and money, ignoring the seismic requirements, and the quality is not much guaranteed. Not only can it not resist the strong effect, but even some strong feelings have led to damage to the house, and some new homes have become dilapidated houses, causing great economic losses, and the lesson is extremely profound.
How to improve the seismic performance of houses in rural areas? Summing up the historical experience, we believe that we should do a good job in the following aspects:
1) Choose a good site, try to avoid old ponds, semi-filled land zones (places that are filled in when leveling the land), and places with soft soil. In mountainous areas, you should also pay attention to avoiding cliffs and steep slopes to prevent landslides from occurring. The selected foundation should be carefully dealt with and tamped.
2) The roof truss should not be too high, so that the center of gravity of the house is lowered, scissor braces (wind braces) should be added between the roof trusses, and diagonal braces should be added between the roof trusses and columns, so that the house has a certain ability to resist shear force, and the integrity of the house is not easy to collapse. If the wall is made of brick-concrete material, it is best to add ring beams or tension bars at certain heights, which can improve the tensile performance and overall performance of the wall.
3) Try to do little or no decoration on the eaves, such as parapets and high door faces, these bulky and unstable appendages are the most likely to collapse; Window on the wall should be opened less or smaller.
4) For adobe walls, it is necessary to choose good viscosity soil, tamping should be uniform and dense, and directly shelving purlins, roof trusses or girders on the earthen wall, which is easy to cause collapse due to wall damage at the bearing beams, so place some wooden pads under purlins, roof trusses or girders to disperse the pressure.
5) The roof should be light, and when building a house in some places, add a layer of cement prefabricated slabs, and put a wooden roof truss mud tile roof on top, which will make the house top-heavy and have poor seismic performance.
6) Ensure the quality of construction, especially the wall of the brick and mud structure should be bitten inside and outside, and no through joints should appear. The brick draft should be sufficient, and the corners should be reinforced with several layers.
The above can effectively improve the seismic performance of the house. Different areas have different habits, but as long as you take into account the earthquake resistance requirements when building a house, and take some measures in combination with the actual situation, you will be prepared and reduce losses.
With the advancement of new rural housing, rural living conditions have improved, but the rural construction market that has been followed for many years is still far from achieving the true meaning of "new countryside".
Please give a good review, thank you.

The foundation is solid, and it seems that there is no money to save money, only if you do it yourself, you may save a little, and now the labor is very expensive.

According to the provisions of the "Land Law", the right to approve the homestead in the countryside lies with the people at the county level, so only after the approval of the county ** and the issuance of the homestead use right certificate, can the house property right certificate be obtained in accordance with the law. Although the residential houses in the rural areas use the rural collective land, the houses built on the homestead land approved only by the collective economic organization (village committee) are illegally occupied, and the house ownership certificate cannot be obtained, and the house built on the self-reserved land or contracted land cannot receive the house ownership certificate.
