Earthquake Proof Building Challenge

My group's building performed as I mostly expected it would. The building survived the first test, which I thought it would, since our building was stable. The second test didn't go quite well because our building didn't have walls to keep the materials from falling out. The third test went well and our group survived through it, because we added walls to help our building at our spare time. Our group didn't succeed through all three tests, but I thought that we created a well stabled building.
The building performed as how I predicted it would. I predicted that our building would succeed the first test, and it did, because I thought that our building was stable since my group tested the building by shaking it and nothing fell out or was damaged. The second test didn't go quite well as I predicted. I thought that our building's third floor was slanted and we didn't have time to fix it, which then caused the materials to fall down first from the third floor. On our last test, I predicted that our building would be capable of holding in all the materials, because our group had time to fix minor problems on the building, and we added stable walls to keep the materials from falling out, which we didn't have at first.
If I had to rebuild the building from scratch, the one thing I would keep would be the cross bracing our group had on the current building. Some things I would change would be the base. Our group stuck popsicles sticks through the boards as cross bracing. We were going to place rubber stoppers at the bottom of the building, but we didn't have enough money and so we just left the popsicles go through the base. The popsicles did make the building quite unstable, but there wasn't any problems with it when the building was tested. I didn't really have much problems with the building, I would just need more time to build it so we can do it properly and slowly.
The materials and supplies weren't a problem. Our group just had two big problems. The first one was the budget. We had a great plan for our building, until we realized on the way that we were buying materials which had the biggest amount of money needed to spend. The building needed those materials, and so we reduced the amount we needed to buy and went to the limited amount needed. The second problem was time. Time was the biggest problem the group struggled with. We were too slow on planning, and we took two days with only planning instead of building, which then caused us to start and finish everything in one day. Our group worried that we wouldn't finish in time, but we did everything efficiently and quickly till the last minute, thought we learned our lesson to plan faster and arrange the timing.
These limiting factors are significant to countries including Turkey, Iran, Pakistan, Philippines, and Nicaragua. These countries have quite a lot of earthquakes occurring in them. I think that the only reason why these countries have barely any earthquake proof buildings are because they don't have the money. Its quite easy to create an earthquake proof building, and a lot of people probably suggested some, but they just don't have enough budget to buy the resources. If my group's building was expensive and it was not really a success, then to make an extremely successful building must need a HUGE amount of money. The only way to solve this problem is for people to create a building that's cheap but earthquake proof and stable.
