Earthquake Resistant Houses of Bamboo

Bamboo has been known by the people of Indonesia, especially in the province of Banten as building materials for hundreds of years, both for the home, aqueducts, bridges etc. Plant bamboo clump can be found in the countryside, even most villagers have bamboo trees in her yard. In addition to the strength of bamboo is quite high (the results of our study, the tensile strength on the skin of bamboo for some types of bamboo exceed the tensile strength steels being), is also very fast growth (3-5 years need only ready cut), tubular has segment, so pliable enough to be used as a column.

Why bamboo buildings are constructed properly can withstand earthquakes? Indeed the construction of buildings with various components can be constructed resistant to earthquakes. In principle, earthquake resistant buildings intended to minimize casualties from the occupants / users of the building. In other words, building occupants can leave the building quake-hit safely in the event of an earthquake.

In accordance with the basic principles of earthquake resistant buildings should be kept as light as possible, then the bamboo material is very fulfilling these requirements. In earthquake-resistant buildings, bamboo can be used as an element of beams, columns, supporting the roof, wall charger, and floor. The use of bamboo (gedhek) for wall elements in buildings such as houses with wood frame houses in the rural parts of the district of Lebak (Kampung Kanekes; Baduy). In addition to use in the form gedhek wicker, bamboo can be used as wall elements in the form of galar or blades mounted horizontally with stretched and plastered with mortar (mortar sand and cement).
Can also form the main webbing woven with directional slats horizontally and plastered with mortar. This construction is quite light but have sufficient flexibility. For the roof truss construction can also use bamboo materials, even in India has been developed with the wave roof laminated woven bamboo.
In principle, earthquake-resistant bamboo houses should be made to the following provisions:
  1. Using bamboo is old, has been preserved and in the dry state;
  2. Bamboo houses built on land that is flat; The foundation and the sloop (sloop diangker to the foundation at every distance of 50 to 100 cm) around the house plans;
  3. The lower end of the bamboo columns entrance to the foundation, diangker and the inside of the lower end of the column is filled with reinforcement and mortar);
  4. Elements associated with the sloop wall or column must diangker in some places, at the top end of the columns are surrounding the ring beam building plans, wall elements should also be in the armature with the ring beam. If there is a wall openings such as winds, windows and doors, should be given a reinforcement in the opening round.
At each meeting of the walls with the other wall section, there must be a column and the column diangker wall. Roof frame (horses) can be constructed with simple supported (joint-roller), in which each holder roof frame should be put in place, and need diangker with columns. Bonds wind on the roof should be installed in every inter horses. Wind bond is mounted on the roof slope field under the roof covering, and on a vertical plane between the two horses.
Excess use of bamboo as a building material, among others:
a. Bamboo is known as a building material that can be updated;
b. No need to use skilled manpower;
c. Simply using simple tools are easy to get around us; Quite comfortable living in a bamboo house;
d. Very short construction period;
e. Cheap construction costs.
In addition to the above advantages, the bamboo building has shortcomings that have not lost the connotation of people that bamboo is known as the building material of the poor, almost no credit facilities from banks, due to lack of belief in the banks, there is no national standard bamboo house.
