A high rise tends to be a safe place during an earthquake due to the amount of engineering and modeling for earthquakes done. But, it isn’t the safest place. Open areas free of obstacles tend to be the safest places.

Which is better for a detached garage, cement block, wood frame, or metal, and why?
Cement block is the most expensive, takes up more room but is far more durable. It is limited in how “nice” it looks from the outside. No insect issues (unless you put a wood roof on it) and very few water issues. Also, it is the most repairable should you run into it. Wood framing …
Does a cement brick walled sump for residential purposes require a PCC or RCC floor (bed)?
Typically, you want a bottom to your sump. Otherwise, you have dirt/mud containing your sump. This can lead to the sump sinking, dirt and rocks trying to go through your sump, or leaking around the sump which you probably didn’t intend as you would have provided leach lines instead of the sump. So, yes. You …
What is the disadvantage of the usage of GGBS in concrete?
If steel manufacturing isn’t local the cost goes up due to transportation costs. In order to get most of the corrosion resistance from GGBS the ratio reduces the 28 day and ultimate strength of the concrete. But this almost always is quite a bit higher than similar concrete without GGBS. GGBS can produce a finer …

What do houses have that apartments don’t?
Most of the time apartments are minimized versions of houses. If it isn’t necessary it isn’t part of the apartment. All apartments are house replacements. Once you get out of the minimized area of apartments they start taking on all the aspects of high-end homes in areas that normally wouldn’t be able to support them …

What material should the water tank be made of?
Underground tanks up to 50,000 gallons – PE, Fiberglass, steel, or concrete Underground tanks more than 50,000 gallons – concrete with liners Pillow tanks up to 40,000 gallons – PE, Fiberglass, steel or concrete Above ground tanks more than 40,000 gallons – steel or concrete
Is it possible to tilt a building by a few degrees if you fill all the rooms on the same side of the building for all floors with water tanks?
Firstly, remember that in your scenario the weight is still applied over the existing base. As buildings are designed to be stable objects this will only result in your tilt if the soil below is undermined during the process or you have a partial collapse of the structure pushing enough of the weight beyond the …
Where is the safest place to live in California in terms of staying away from large earthquakes?
Okay. This is the map structural engineers use to determine earthquake forces. First. There is no place on earth earthquake cannot occur. That being said, there are roughly two areas of California that experience the least, or at least, the mildest earthquakes. The northern central valley extending up to around Eureka. The second is around …
If an object with some mass was sitting there floating in space then suddenly lost a little bit of mass, would this cause an acceleration of the object?
Depends on a few things. Normally this would be an F=ma problem, but we don’t know enough about the starting conditions. Scenario 1. The mass was at rest or was at a constant velocity with no acceleration, but loses mass without additional force. The mass stays at rest, or no acceleration. Scenario 2. The mass …
How strong does an earthquake have to be to cause damage?
It is highly dependant on the magnitude, and your distance from the quake origin (surface and depth of the quake). A shallow 3.0 can significantly damage a building located at the epicenter.
