Soft storey structure collapse led to so many deaths in the 2023 Turkey/Syria earthquake... we as engineers need to find a way to ensure that corners are not cut when building soft storey structures in seismic zones in developing countries. I don't know too much about this, but it seems that a mass produced, affordable joint strengthening component would be needed to avoid builders reducing their costs by under-reinforcing their concrete joints.

Pretty much everything post 1981 is built ready for the super quakes. But the newer houses even have special dampeners and some are built on pads that shift with the quake causing the house to basically not move during an earthquake

People build like this because lots of people still absolutely need cars. There would need to be massive redesign and restructuring in order to make every feasible to live in without cars. In my city, taking away cars would legitimately starve some neighborhoods. Others would essentially become self-contained little villages with little contact with nearby neighborhoods. Lots of amenities are so far away by foot you'd have to walk all day. Our public transportation is not good enough to get people places easily. It's often thrice the time to get somewhere by public transport compared to car. And don't forget, not everyone is in good enough health to survive without driving. Driving lets unhealthy or physically frail people get around with little physical exertion. I, too would enjoy a world with better options for not having a car. But in order to achieve that I think we have to remember that most people have very good reasons for owning one in the first place. We have to come up with solutions that improve the quality of life for those people, and the changes required are massive. I would be content (as a start) with improving the efficiency and reducing the pollution and cost of public transport and private cars. Improve electric cars, improve fuel efficiency for all gas cars, update subways and busses and lightrails, etc. Make it easy for young, healthy people to get around without a car. Encourage businesses to open in local neighborhoods without businesses. That sort of thing. Because completely redesigning a mostly occupied city is horrendously hard, and will take a long time no matter what. I'd rather take the time we will use to work towards that anyway and make small achievable changes first.

Even better, how about NO parking? Investing in REAL infrastructure that doesn’t feed the car-centric hell hole we live in? Then buildings can have actual usable space that is cheaper since you don’t even have to pay to build parking! Just imagine: instead of huge concrete parking lots, we could have public parks and plazas, schools, shopping districts full of local businesses. Places to go and people to see! Instead of loud and smelly cars driven by people who don’t care for the lives of you or your children.

@@frootluips7970 Keep dreaming pipe dreams. Car-Free places only work in small countries where you don't have to travel far. How TF are people spread out over long distances supposed to get anything done? If you live in some place like Japan where it's mostly cities close together, or some European countries, sure. Going without a car is feasible if the furthest you need to travel is a mile or two. But here in the good ole US of A, I travel 20 _miles_ to work, and 20 _miles_ back home and I live in a rural area, the largest town near me is the one I work in, and its population is about 4,000 and it's like 15 miles away from downtown (I work on the other side of the town). Cars are important here, because we have all this landmass and people like to travel, and many people enjoy suburbs, and travel to the cities. If you don't account for that, then cities can't function, because they are basically making it very difficult, if not impossible, for those living in the suburbs to visit.

We had a weird solution in middle school. The school had a machine that would simulate small scale quakes, and our assignment was to build a structure with office supplies. Our winning build uses rolled up index cards as the corner pillars with string running through them and securing the top of the structure to the foundation, like one of those old toys of like, a horse made out of beads that would collapse when you squeezed the base and right itself when the tension returned.

This had been a big concern in San Fransisco, because most residential buildings have these soft story ground levels. and its led to a rush of retrofits as they prepare for th next big one. Another way to retrofit a soft story building is to run steel tension rods all the way from the foundation to the roof, this links all the floors together and keeps them from shaking out of sync.

Pretty impractical in the modern environment when the final destination of trips is extremely divers both spatially and with time. Buses that that run from the suburbs to the city centre or to something big such as a large factory or university are workable certainly but it's far more problematic for anything else. Too few people going to and from the same points to make it viable. There's a role for public transport but cars are here to stay, they're the practical means for the majority of trips that involve a destination that isn't the city center / downtown or some other destination where large numbers want to travel to at the same time.
