Indonesia is located on the southwestern edge of the Pacific Ring of Fire. This resulted in high volcanic activity and the risk of earthquakes. When starting to decide to buy or build a house, it is necessary to consider the resilience of the house against natural disasters, especially earthquakes in accordance with the Law Building N0. 28/2002. The earthquake that followed by the tsunami in the Indian Ocean in 2004 and the earthquake in Jogjakarta in 2006 showed that earthquake-resistant construction is indispensable in Indonesia. Earthquake-resistant buildings are resistant to small earthquakes, suffering only minor damage to medium-large earthquakes. Even if the building is severely damaged by the earthquake, the building will not stand to collapse on its inhabitants.
The earthquake-resistant building locks are in sturdy construction and use lightweight materials. Foundation, column, and roof horses should be built with strong construction. All components of the house must also blend perfectly. Roofs and walls should use lightweight materials. When shaken by the earthquake, the momentum of light materials while swinging is not so great. Heavy objects swung hard when shaken by an earthquake, high risk for falling or collapsing.
Building earthquake resistant homes starts with a solid foundation. Constant rock foundations must be on stable ground and dug until it reaches hard ground. If the soil is soft, it should be hardened and stabilized first. Each elbow should also be exactly 90 degree angle. The foundation must be fused with columns and on the foundation there must be a sloop that tightly binds the columns. Sloop should also be given an armature with a foundation at any distance of 0.5 meters so that both are tightly bound.
The walls of the house should be made of lightweight bricks or wooden planks. This wall should be put together with the column using the armature. To withstand horizontal movement during an earthquake, cross links are required to make the walls more rigid and sturdy. Wide openings such as doors and windows should be lintel beams that are usually installed on the upper frame. Without this, windows can be thrown from the wall when rocked by a powerful earthquake.
The column is required for every 12 m2 area on the wall, its function is like a house pole. All columns must be firmly embedded into the foundation and there are beams that bind all the columns. If the column is under the horses, the oblique legs of the roof horses must merge with the column underneath to strengthen the roof.
Lightweight roofs are more resistant to earthquake shocks, so the roof of zinc or shingle is better than precarious. Roof is able to withstand the heat of the sun, but the ceramic tile is heavier than other types of roof. The wood is light enough for the roof frame, but the horses and roof frames made of aluminum other than light are also free from termite attack. The horses also have to fuse closely with other horses using lintel sticks.
Earthquake resistant buildings must follow the standard in the building, from stirring cement dough, setting up columns, and others. All must be standard. All components must be closely tied to one another, both structural and non-structural components. When building or buying a house, it is necessary to consider the building’s resistance to the earthquake. Make sure the developers who build our homes follow the standards that exist, given that almost all of Indonesia is vulnerable to earthquake risk. If you are going to buy a finished house, check first whether the house is built in accordance with the condition of Indonesia is prone to earthquakes.
