Some time ago, a number of regions in parts of the country were rocked by an earthquake. Many victims arise because of this natural disaster. Houses collapsed because they couldn’t stand earthquake shocks. Because it is located right on the Pacific ring of fire, some countries are prone to earthquakes. It can not be avoided, but it can be anticipated. One of them is by building earthquake resistant houses. Earthquake resistant house construction is stronger than ordinary houses. Well, here are some things to consider when building a house.
Soil From Thick Components
To build earthquake resistant houses, soil conditions must be considered. Soft, easy to dig and soft sandy soil is not suitable for strong home construction. If the water level is less than 2 meters, the soil is also considered not good. Conversely, if the water is at a deeper level, the soil is good and stable. Judging from its components, good soils are those that have sandy gravel, clay, solid, and hard. This is the right location to build earthquake resistant houses.
The Foundation Must Be Strong
In some locations, soil quality is not as good as desired. However, this can still be anticipated by creating a strong building foundation. If the soil is hard, the minimum foundation size is a minimum width of 30 cm, a minimum width of 60 cm, and a height of 60 cm. The main structure of this building must also use a binding beam.
Pay attention to the roof structure
The ampig frame comes from reinforced concrete structures. Ampig is a brick arrangement, the composition of mortar and sand is 1: 4, then plastered. To minimize the risk if the ampig collapses, the recommended materials are lightweight materials such as boards or GRC (Glassfiber Reinforced Cement).
Wall Structure Must Fit
The anchor diameter on the wall is 10 ml and installed every 6 layers of brick with a length of 40 cm. Then, the walls are plastered with a mixture of cement and sand 1: 4. 2 cm thick. The longest wall area is 9 square meters. The distance between the columns is the longest 3 meters.
Earthquake Resistant Provisions
There are several other provisions to build earthquake resistant houses, namely the supporting wall must be symmetrical and uniform. There is no concentration of weight that is too large at the top of the house. If the house has two floors, the supporting wall on the lower floor must be longer than the wall on the upper floor.
One form of earthquake resistant houses is Monolithic Domes. Shaped like a dome, this house looks unique. To build it also need to use special methods, namely air circulation technology, concrete using steel bones, and polyurethane foam insulation.
Another type of house is Danshin Water. Houses like this are found in Japan. As an area that is often hit by earthquakes, Japan is very concerned about building houses. To withstand earthquakes, they use airbag technology. So, a house can float around 3 cm if an earthquake occurs.
At Stanford, there is a building called Seismic Isolators House. This building uses a shifting insulator so that it makes the house shift when an earthquake occurs. The construction of earthquake-resistant houses in Indonesia is increasingly being socialized. Thus, the risk of death and damage can be reduced.
