Let us consider the main principles in building earthquake resistant housing , the principles are as follows:
1. Plan and the Structure of Its Symmetrical
Building Plan. Plan a simple and symmetrical will help us determine the location of the points column and the foundation will be the main struktur order in our homes. For example, for the reinforced concrete columns are ideal for residences are usually within 3-4 m.
Structure. The structure is simple and symmetrical buildings can withstand seismic forces better than in buildings with irregular shapes. This is because the force of the earthquake can be distributed evenly to all the elements of the structure.

2. Selection Against Earthquake-Friendly Materials
Magnitude earthquake that struck the style of a building is directly proportional to the weight of the building itself. That is why it is important to make the building into a lighter by using lightweight building materials.
Japan is a country with earthquake-resistant construction technology is best. That’s because they did unbelievably region is prone to earthquakes. If you look at most of the traditional Japanese houses and the wooden structure is generally one level. The partition between the room wearing bamboo and paper is very mild.
Selection of Building Materials for Home Earthquake
Columns and beams of wood or bamboo . In addition to system construction and a good connection, earthquake resistant houses also require a lightweight and strong material. Due to the growing weight of the building the greater the force of earthquake that happened. A simple example is the traditional home of various places in Indonesia that was more earthquake-resistant than modern homes. This is due to the material used mostly from wood and bamboo are lightweight and flexible.
Who says wood and bamboo homes are not sturdy and durable? History proves that house can last hundreds of years. Let us look too traditional Japanese houses are made of wood and bamboo can be established for hundreds of years after the quake struck dozens of times. It shows indeed wood and bamboo building materials that have been tested toughness.
Modern house in Indonesia used to wear as a brick or concrete block wall material. It is brittle and inflexible make these materials do not withstand earthquakes. However, for reasons of solidity against shock, fire, wind and other security reasons many people still prefer brick walls. If you insist you must abide by the rules of earthquake-resistant structures. Some examples are:
- Placement columns rarely practical in every 2- 3 m along the wall
- Brick walls have to be anchors to each column within the composition 8 brick.
- Do not install directly over the brick roof load but must be given a sufficient beam with reinforcement.
- Foundations, walls and beams sloop is a single unit that is able to reduce the tremor.
In lieu of a brick wall, you can replace them with lightweight aerated concrete as the brand Hebel and Primacon. Available in the form of lightweight concrete blocks and panels that can be used for walls, floor slabs or stairs.
With the B-panel walls . B-panel system which is a new technology sandwich wall. These panels use foam material b very lightly coated with wiremesh for flexibility in structure. Lightweight and flexible in accordance with the terms of earthquake resistant houses.
If you want to manufacture the walls of a fast, lightweight and earthquake-proof you can replace the conventional structure with light steel wall frame structure. This structure is not only replace the function of the wall, but also replace the function of the column and can support a load of existing structures on it. Thus the use of this frame structure tidakcladding-house again require columns and beams.
Wall With Metal Cladding & Fiber Cement . For wall covering material, the exterior could use light steel wall panels (metal cladding), GRC, fiber cement (calsiboard) or wood. As for the inner wall could use gypsum. With a good finish outer appearance will not be much different from using conventional systems.
Tempered glass wall . In addition it should also be noted the use of glass in a window, door or roof. The use of ordinary glass is very dangerous because it is likely to rupture at a time when the quake and injure the occupants. The use of tempered glass is highly recommended although it is relatively expensive. The glass is very safe because if broken fragments form a very small so it will not hurt the residents of the house. Another alternative is to use a similar sticker on the glass so that the pieces will not be directly on the floor.
With Zink Alume roof . For roofing material to avoid the use of concrete roof tiles or ceramic tiles are heavy. The use of roof zinkalume (a mixture of zinc and aluminum) or roof light asbestos preferred. The use of polycarbonate with a varied choice of color is one option. Jam, it can also be used metal tile or shingle to get a better view.
The concept of building earthquake-resistant houses is essentially an effort to make the whole house elements into a coherent whole that is not easily collapsed in the quake. To realize the right choice of materials required, the connection element strong enough and of course the appropriate implementation planning.
