Means of creating earthquake resistant buildings in an…
- Computer controlled weights in the roof help to reduce movement by travelling around to specific places to balance out the movement of the building, and help prevent it from toppling
- Steel frames can sway, which reduces strain on the building during movement, so reducing the chance of a collapse
- Automatic window shutters prevent any glass that breaks from falling on anyone
- Open areas close to buildings allow anyone who has been evacuated to assemble. This allows people to be checked for so that emergency services know how many people are missing, and means that even if something does collapse, it is less likely to fall on anybody
- Foundations are sunk into the bedrock to avoid clays. Clay can easily enter liquefaction, which makes collapses more likely and also more devastating when occur
- “Birdcage” style interlocking frame on the exterior provides a stronger overall structure, meaning less of the building will collapse if there is damage
- Panels are attached with flexible joins to the outside. Materials to be flexible so that the sudden strains that the earthquake applies cause less damage, which stops them from bending or snapping
- Road system built to allow quick access for emergency services. This allows faster response times after an earthquake, and helps limit secondary impacts, such as fires, from occurring, and saves some of the victims’ lives
- Rubber shock- absorbers take the initial impact before the main foundations can be hit
- Education and training – show people, especially poor people, how to build more robustly, and how to use resources more sustainably and cost-effectively
- Incorporate new engineering techniques – lighty reinforced flat slab foundation below two layers of reinforced hollow concrete bricks (designed to cause minimal damage in the case of a collapse) forming the base of the wall, covered by damp proofing (to protect against moisture and insects). Wall frames formed of timber latticed with treated bamboo gives high strength and flexibility to a fairly light structure. Galvanised chicken mesh is attached to this so that outer materials, such as cement render can hang on it.
- Replacing old materials – remove heavy clay roof tiles and replace them with a lightweight corrugated cement-fibreboard roof. This reduces the load on the walls, and in turn, both the chance of collapse and risk of injury if it does collapse
- Reinforced steel corner pillars provide strength and flexibility to the structure
- Any work with mixed stone pieces can use parts of other homes which collapsed during quakes- this would prevent the accumulation of debris, and quick action to gather it could assist aid workers.
