Bamboo is a renewable building material and is widely available in Indonesia. From about 1,250 species of bamboo in the world, 140 species or 11% of them are native to Indonesia. In Indonesia have long used bamboo for building houses, furniture, farm equipment, crafts, musical instruments, and food. However, bamboo is not a priority of development and is still seen as “poor people’s material that easily damaged.”
Bamboo has a power that can to compete with steel. Due to that high flexibility and strength, the structure of bamboo is also an earthquake-resistant building.
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)
- Foundation and Sloof (Sloof plugged into the foundation at each distance 50-100 cm) around the house plans
- The lower end of the bamboo columns go to the foundation and the inside of the lower end of the column is filled with reinforcement and mortar),
- Elements associated with the column wall should be plugged in some places,
- At the end of the column is given a ring that circled the block plan of the building, wall elements must also be plugged in to the ring beam,
- If there are wall openings such as wind-wind, windows and doors, should be strengthened in the opening round.
- At each meeting of the wall with the other wall.
- Framework of the roof (the horses) can be constructed with a simple pedestal (joint-rollers), where every seat frame roof should be put in place.
- Association of the wind on the roof should be installed at each inter horses. This wind ties, installed at the field slope of the roof under the roof covering, and in the vertical plane between two horses.
