>>13430876>Steel frames are easy to maintain, you just have to sand any corrosion and paint it over. Corrosion eats away steel, which reduces load-bearing capacity. Furthermore, steel frames experience fatigue.
>Steel frames are light and dont need heavy foundations >and dont need heavy foundations Please explain to me where steel frames make the load go? Is there some magic to them that makes forcce disappear into thin air?
The foundation is equally massive for a steel frame, Idiot.
>and can be assembled in days by inexpert crews using bolts and cranesConstructing anything more advanced than a single-story portal frame (such as the one in your picture) is not simple. Bolted connections may require welding (if it is to take moment) and always require installation of the bolts, which is time-consuming and expensive.
> Any mistake can be fixed.No. If you fuck up the bracing required during installation, your steel frame will buckle. If you weld incorrectly, you can only "fix" it once (not even once with high-strength steel). If you fuck up a bolt placement, the connection will fail in use.
