Possibly, this will be changed with more modern vehicles and experience. These steel carparks were exceptions, as most carparks in Australia are cast in place, posttensioned.
It was interesting. If I'm there again I might have another look. To be honest I'm quite used to seeing poor steel design and detailing in Australian structures. Nothing seems badly amiss here, though I didn't look closely.dik said:Interesting structure.
Yes. This was the ground floor with two levels above. I would presume that HSS was used to minimise the surface area to mass ratio. In other locations of very high load where transfer beams were present heavy I-sections were used.dik said:HSS columns to US of beams with stiffeners to carry what I assume are column loads through the beams.
I'd say you have mostly read that correctly.dik said:The beams being continuous to minimise moment. The secondary beams at nearly 1/3 points to minimise the moment again and slightly offset from the columns as not to interfere with the column load transfer. If I read that correctly.
