In order to become a building that is resistant to earthquake then the structure of the building needs to be considered. As in the review, this structure will discuss Footings, columns/ post, roofs, and walls.
The Footing is a lower structure that holds the structure above and forwards the load to the ground so that the Footing satisfies the following.
The Footing should be placed on a solid ground, the Footing laid on the hard ground. Footing lies deeper than 45 cm below ground level. The whole Footing must lie on a strong ground.
The Footing must be connected to the Footing belt (sloof), this is given to the local Footing as well as the continuous Footing.
The Footing beam (sloof) should be lumped on the Footing with a 1.5 m with 12 mm diameter iron reinforcement.
The Footing should not be placed too close to the cliff wall to avoid landslides. To prevent cliff slopes, the soil is given a retaining wall from the stone pairs of times or from bamboo or wooden plaster.
2. Column / Column.
columns or poles to help the wall in holding the load above it while making the wall into a ductile wall. The things to note in the column are as follows.
Buildings should use columns as load-bearing elements, eg using reinforced concrete columns.
The column should be laid on the Footing beam (sloof) or the bond is passed to the Footing.
At the top end of the column is repeated or each column must be tied and put together with the beam around / ring balk.
Building frames (Sloof, beams, and columns) should have a strong and sturdy relationship.
The column should be equipped with a stiffening beam (ring balk, latei beam) to withstand the lateral force of the earthquake.
3. Building Beams.
The beams on simple house building consist of ring balk (beam around) and lintel beam. Latex beam/lintel has a function as a horizontal reinforcement and is generally located above the frame. Crosslinks can be mounted when possible.
4. Roof Building.
The roof structure needs to pay attention to the following points.
As discussed upfront, the roof should have a lightweight by using materials such as zinc, asbestos, aluminum or other lightweight materials.
The framework of the Truss must be strong to withstand the roof load and should be levied on its support that is on the column or ring beam.
In the longitudinal direction, the roof should be reinforced with a wind bond between the truss of the Truss.
The walls in particular of cement walls have the following uses.
The building wall in the event of an earthquake will receive the surface load in the direction perpendicular to the wall and the shear load on the parallel direction of the wall.
The strength of the inner wall of the load is influenced by the existence of the armature on the wall side and the reinforcement (practical column) on the wall itself.
The walls should be haunted in columns with a length of armature 1.5 times the length of a brick or brick. In addition, the armature is installed every 10 layers of red brick or every 3 layers of brick.
The walls of ampigs (mountains) will experience a large deflection when shaken by the earthquake because it is located at the highest part. Therefore, the mountains require the reinforcement of a wall frame.
The walls should be provided with practical columns and binding beams on sections of the wall that have an area of more than 12 m2 or wall length 15 times wall thickness.
Installation of ½ brick walls should be reinforced by practical columns binding both with sloof (foot) and ring beams at the top of the wall.
