Bamboo is a renewable building materials and widely available in Indonesia. From about 1250 species of bamboo in the world, 140 species or 11% are species native to Indonesia. in Indonesia had long use of bamboo for building houses, furniture, farm equipment, crafts, musical instruments, and the food. However, bamboo is not a priority for development and is still viewed as "property-poor material that quickly broken."Bamboo has a strength that can compared with steel.
Due to the high flexibility and strength, the bamboo structure is earthquake resistant buildings.In principle, earthquake-resistant bamboo houses should be made with the following conditions:
Using bamboo is old, has been preserved and in the dry state,
Bamboo houses built on flat ground (solid)
Foundations and Sloof (Sloof anchored to the foundation in every distance of 50-100 cm) around the house plans,
Lower end of the bamboo column entrance to the foundation, anchored and the inside of the lower end of the column filled with reinforcement and mortar),Elements associated with Sloof wall or column should be anchored in some places,
At the upper end of the column was given a ring beam around the building floor plan, wall elements must also be haunted by the ring beam, If there are wall openings such as wind-wind, windows and doors, must be strengthened in the opening round, At each meeting the wall with the other walls, columns and walls must be anchored to that column, Roof truss (the horses) can be constructed with a simple pedestal (hinge-roller), in which each holder of the roof truss to be placed in position, and need anchored by columns.
Institute of the wind on the roof should be installed at each inter horses. This wind ties installed on the slope of the roof area below the roof covering, and in a vertical plane between two horses.
Excess use of bamboo as building material:
- Bamboo is known as building materials that can be updated
- No need to hire well-educated,
- Simply use the simple tools are easily available around us,
- Quite comfortable living in bamboo houses,
- Construction period is very short,
- The cost of cheap construction.
In addition to the above advantages, the building has a shortage of bamboo, among others:
Not the loss of connotation in society that the bamboo is known as the poor building materials,
Almost no credit facilities from banks, due to less confident the banks,
There are currently no national standard bamboo house.
The durability of building materials bamboo is a combination of preservation and design of the building itself.
Preservation protects the bamboo buildings of the enemy that is biological powder beetles, termites and fungi.
While the design must also be friendly with bamboo bamboo materials and are able to protect the bamboo from humidity, rain and scorching heat that can physically damage the bamboo.
