Sandwich wall Panel: More Lightweight But Stronger For Earthquake Resistant Houses

Thursday, May 12th, 2011 by # Architectural Modern, Minimalist House Design

Earthquake is a natural phenomenon that often occurs in Indonesia, because in general areas of Indonesia have volcanic activity level is very high, and also has a base layer of soil sufficient to trigger the earthquake-prone tectonics.
Basically, inhabited buildings are damaged or destroyed due to building structures that are not quite light and do not have a level of unity of the wall (monolith) is sufficient.
A. Principles of Earthquake Resistant Buildings
1. Plan a simple and symmetrical
Investigation of damage caused by the earthquake showed the importance of building a simple layout and structural elements resisting horizontal forces are symmetrical. Such structures can withstand earthquake forces Iebih either because of lack of effect of torque and a more equitable kekekuatannya.
2. Building materials should be as light as possible
Due to the limited choice of building materials, the designers of the building using conventional building materials are generally heavy, but it would be better if using a lightweight building materials such as the building material made from sandwich panels. This is because the magnitude quake inertial load is proportional to the weight of building materials.
3. Institute of buildings should form a solid unity
If we look at the condition of conventional buildings after the earthquake, there are still many visible condition of the walls in buildings separate from the column. This shows that the more monolithic (single unit), a wall will minimize the collapse of the effects of the earthquake.
4. The need for load restraint system of adequate construction
In order for a building to withstand earthquakes, seismic inertial forces should be channeled from every element of the structure to the main structure of the horizontal force. Then move these forces to the foundation and the ground. It will be very important if the main structure of the horizontal force resisting it is elastic. Because if the elastic force is exceeded, brittle failure that suddenly will not happen, but in certain places will be seen the pattern of cracks / deflection first.
One of the advantages of b-panel is to have a lighter weight compared to the wall with conventional methods. And also has a pattern of monolithic wall that is connected between the wall of the one with the other walls have wiremesh functioning due to tightly bind to each other.
B-panel system not only for wall applications only structure, but also can be applied to the floor, no roof and the stairs to the characteristics of the insulation (thermal / acoustic) and excellent earthquake resistance.
B-panel Wall Materials
B-panel wall is a type of sandwich wall panels (wall-coated material) consisting of 3 mateial.
1. b-foam
Materials made of polystyrene with a minimum density of 12 kg/m3.
2. High Quality Steel (wiremesh)
High Quality Steel was carried out together with a special design diameter of 3mm (quality U-50).
3. Plaster Concrete shotcrete
Plaster with shotcrete useful way to wrap wiremesh thus forming the concrete wall structure with a thickness of 3cm on both sides
