Why can't we build an earthquake-resistant building?

In summary, when constructing a building, it is important to consider the forces involved, particularly those of earthquakes. While trees can resist earthquakes, buildings may not be able to do so as easily. However, engineers are constantly working on creating earthquake-resistant structures by studying natural vibrational modes and frequency response. The cost of making a building completely proof against earthquakes may be prohibitive, but advancements in earthquake engineering are being made through research and updates to building codes.

What are the forces that we need to consider when constructing a building?
when there are tree that can resist an earthquake why can't a building resist it?

We can build them. There are plenty of earthquake resistant buildings in California.

There is of course a difference between earthquake resistant and earthquake proof.

Japan is also on the forefront of engineering in earthquake resistant structures. The basic idea is engineers take a very close look at a structure's natural vibrational modes and frequency response to the forcing frequency of an earthquake, based on empirical measurment.

Ultimately it's a question of cost. You could build a building that was totally proof against an earthquake, but you wouldn't want to pay for, or live in, a bomb shelter.

lots of people are working on it. my civil department specializes in seismic design

Simple answer: trees bend. Bricks don't.

You might want to visit the Earthquake Engineering Research Institute (EERI) web site.

If you are nearby to Oakland, they used to also have some really neat exhibits at their HQ. It's also close to Jack London Square and you can see the original models for the Imperial Walkers (a plug for Oakland).

With every big (high magnitude in richter scale) earthquake more research is done, and building codes get updated thus buildings get more resistant to earthquakes.
 

Related to Why can't we build an earthquake-resistant building?

1. Why is it so difficult to build an earthquake-resistant building?

Building an earthquake-resistant structure involves taking into account a variety of factors such as the type and location of the building, the materials used, and the potential impact of seismic activity. It requires a complex understanding of structural engineering, geology, and seismology.

2. What are the main challenges in constructing earthquake-resistant buildings?

The main challenges in constructing earthquake-resistant buildings include ensuring that the structure can withstand the ground shaking caused by an earthquake, preventing collapse through proper building design and materials, and considering the potential for aftershocks or secondary hazards such as landslides.

3. Can any building be made earthquake-resistant?

While there are certain design and construction techniques that can make a building more resistant to earthquakes, it is impossible to completely earthquake-proof a structure. The best that can be done is to minimize damage and ensure the safety of occupants during a seismic event.

4. How do engineers design buildings to be earthquake-resistant?

Engineers use a variety of techniques to design earthquake-resistant buildings, such as incorporating flexible joints and shock absorbers, using stronger materials, and creating a symmetrical and balanced structure. They also consider the location and potential intensity of seismic activity to inform their design decisions.

5. Are there any types of buildings that are more earthquake-resistant than others?

Generally, buildings with a simple and symmetrical design tend to be more earthquake-resistant than complex or irregularly shaped structures. Additionally, buildings made of reinforced concrete or steel are generally more resistant to earthquakes than buildings made of unreinforced masonry or wood.
