From march to april of this year, there were four sensitive earthquakes in shanxi province, and knowledge of earthquake mitigation became the subject of discussion. Of these, three were in the salt lake area of the city, on 12 march at 11:14:44:4:30:30:30:15 march; and on 27 march:3. 58:3. 5:1:04:49:41:14:30:30:30:30:30:15; and on 7 april:1:04:49:40:40:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30; and on 27 march:05:05:05:05:05:05:05:05:05:05:05:05:05:05:05:05:04:04:04:04:04:04:04:04:04:30:04:04:04:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30:30。
The collapse of the wall was the primary threat to the physical security of property when the earthquake struck the house, which was an indispensable home for living and working on a day-to-day basis. What kind of house is resilient to earthquakes? What do you need to pay attention to? On 7 april, the department of earthquakes in shanxi province launched a design reward for the new rural earthquake-resistant housing in the northern part of the province, proposing five principles and four design ideas。
The principle of earthquake resistance to brick construction:
1. The rules governing the shape of houses are such that the size of multi-storey brick houses should not be excessive。
2. Houses should not be opened too large. They should be multi-walled and as heavy as possible。
3. The wall opening rate should not be excessive。
4. The corner of the wall shall be reinforced with steel。
5. Sets steel-fed concrete beams and tectonic columns。
In view of the situation in the mountainous areas north-west of the mountain, the following ideas were designed:
1. For mountainous areas, an independent residential base covers an area of 180 m2. In areas with complex terrain, dwellings can be arranged in spot form; the right and right combinations can be arranged in rows and fine-looking。
2. In accordance with rural customs, the dwelling is a proper house, the compound is located in the south-east and the kitchen and toilet are located in the north-west corner。
3. From the practical point of view of arid water scarcity in mountainous areas, each home has a rainwater cellar。
4. There is a small garden in front of the house, a biogas pool in the north-west corner of the backyard, a chicken or rabbit house in the north-east corner and an agricultural shed in the east. The front yard is empty, the backyard is in, and small agricultural motor vehicles can drive directly into the shed。
The above information was provided by the authorities of the earthquake bureau of shanxi province, with reference to the atlas of new rural housing designs in shanxi province, and the china earthquake information network (samaxi information/shang kai)
