I'm now willing to bet that Hanshin Electric Railway (private company that owns the line services and infrastructure) was forced by thw government to update the Namba Line bridge over the estuary of the Yodogawa due to flood risks (as well as earthquake risk, because it is Japan). It is a vital...
Wow, that sounds very (and extremely) stupid to build a bridge like that to be intended to be used for 50-150 years but just to be destroyed only 15-40 years later (varies widely, so large range) when the next predicted large storm surge comes (that is totally expected and would be abnormal and...
So, are you saying that you guess it took all the way until the mid- to late-1970s for legislation to catch up to the reality of forseeable storm surges and forseeable flood stages, which have been well-established concepts in meteorology and hydrology ever since the scientific method was...
Yes, ships are getting larger, but I'm only talking about portions of bridges that are low-level here, which pre-industrial ships can't fit under anyway. I'm just wondering why many bridges up until the early-mid 1960s were built at seawall height and not boardwalk/amusement pier height, which...
Why were so many pre-1970 bridges built so low to the water that they do not even allow a single-level stand-up boat (serving as water buses or small fishing/research vessels) to pass underneath without raising or swinging the span? If they're built so low with short spans anyway, why not make...
To make it simple, will 3 230-lb men on each mattress in this bed:

in a bedroom that barely fits these 2 beds (but with ladders placed in the aisle rather than end) and leaves a 1-foot wide aisle in the middle (it has a sliding...
RontheRedneck,
Then how about 6 230-lb 6ft-6in tall highly fit men in a full size (54" * 75" = 4050 sqin = 28.125 sqft) triple bunk bed, where it is actually a decently comfortable size for those highly fine men to sleep in? Add 2 inches on all sides for the support posts and 6 inches on one...
I just want to know whether the floor will have a significsnt chance of collapsing or at least have a significant chance of being structurally damaged under these very specific conditions or not.
Actually, this isn't science fiction, and is instead realistic fiction, because it doesn't even come close to violating any laws of hard science and the mechanisms are all known here, unlike faster than light travel (violates causality) or electrogravitics (doesn't violate anything but mechanism...
They would be used in the US and Canada, just that it is a hypothetical in which the population is much larger, cellular agriculture gets perfected so everyone has plenty of food despite limited farmland, there is net zero GHG emissions, there is no crime and everyone is friendly, people are...
But I mean at 2.06 times the rated load, not at 2.06 times the design limit load. I couldn't find the minimum factor of safety that the IBC or IRC specifies for floors, so I don't know how much it is over the design limit for a minimum code building. I actually want to know how much over the...
In other words, I'm trying to know whether or not a light wooden-framed building in good condition, built to the minimum factor of safety allowed by the most lax manual (probably the International Residential Code) of the International Code Council, without structural defects, and having dynamic...
In other words, I'm trying to know whether or not a light wooden-framed building built to the minimum safety factor allowed by the laxest manual from the International Code Council (probably the International Residential Code), in good condition, without structural defects, and having dynamic...
In other words, I'm trying to know whether or not a light wooden-framed building in good condition, without structural defects, and having dynamic loads below 20% of that of static loads, being sustained statically overloaded to 2.06 times the rated load for all bedrooms and being sustained...
