The Materials – The most dangerous type of earthquakes are ones that trigger horizontal movements, because tall buildings are better at resisting vertical loads than horizontal ones. These ground motions can damage building foundations in a matter of minutes, causing severe injuries and deaths.
- Building a structure to withstand seismic waves starts with the right materials with the right properties, and steel is by far the most widely used material for building earthquake-resistant buildings.
- According to the World Steel Association, ductile buildings are safer as they dissipate energy from seismic waves.
A building will typically have ductile parts that can undergo plastic deformations without complete structural failure during an earthquake. Steel is the most common type of material for such parts. Moreover, due to the law of inertia, the lighter the building, the less force seismic waves will exert on the building.
Can timber protect buildings from earthquakes?
Step 4: Procedure – 1. For this experiment, the independent variable is the type of building material used – timber, brick or concrete. The dependent variable is the amount of vibration absorbed by the building material. This is determined by measuring the height of the waves which form inside the tray of water.
- The constants (control variables) are the size of the tray, the depth of the water, the weight of the ball and the length of the string.2.
- The string is used to tie the metal ball and suspend it from the ceiling or from a coat hanger.
- The suspended metal ball should be able to swing freely as shown.3.
The timber is placed on the small table. The length of the string is adjusted so that when the metal ball swings towards the table, it will knock against the side of the timber 3. The timber is placed on the small table. The length of the string is adjusted so that when the metal ball swings towards the table, it will knock against the side of the timber 4.
- The transparent tray is filled with water up to 2 cm deep.
- The tray is then placed on top of the timber.
- Once the water is calm and settled, swing the metal ball and allow it to knock against the side of the timber.
- Observe and record the height of the wave in the water during impact.
- Repeat the test 4 times and record the results in the table given below.5.
Procedures 3 and 4 are repeated using the bricks and the concrete slab. All the measured results are recorded in the table given below.5. Procedures 3 and 4 are repeated using the bricks and the concrete slab. All the measured results are recorded in the table given below.
What is the best material to build an earthquake proof house?
Structure Materials – There are certain materials you can use for your home’s infrastructure that will withstand earthquake vibrations better than others. Concrete is very good at resisting damage and wood is great for building a good, strong frame in this case.
If your home is built out of wood, you will need to ensure that it is bolted down at the foundations because if it is not, the force from an earthquake can cause it to move. This shifting, even minimal as it might be, can create permanent structural damage. If your home is built out of concrete, you should try to have the concrete reinforced with either additional concrete slabs or steel.
For any brickwork buildings or structures, such as garages or garden walls, ensure that they are reinforced with concrete slabs as well since this will offer some protection from tremors.

Is concrete or steel better for earthquake resistance?
Earthquake Resistant Materials – Conventional wisdom in the first half of the 20 th century was the heavier a building was, the safer it would be in the face of an earthquake; however, recent architectural studies have found that buildings made out of materials like concrete or bricks are actually at a disadvantage when experiencing an earthquake.
- As the earth moves, the weight of the building slams against the structural pieces from side to side.
- Therefore, the heavier the building, the more force it exerts on these structural elements, and the more likely it is to come crashing down.
- However, buildings consisting primarily of steel or other metals are much better at resisting earthquakes.
Steel is much lighter than concrete, but it still brings a great deal of durability to construction projects. More flexible than concrete and other building materials, steel is more likely to bend instead of break when experiencing seismic force. Because of these attributes, buildings constructed primarily from steel require less earthquake proofing than those made from other materials.
