1. Have there been multistorey (I have in mind 7 suspended parking levels, serving a shopping mall) precast concrete garages built that satisfy structural integrity considerations (i.e. protection against "progressive collapse")?
2. If so, can you give some examples, and approximtely the year they were built, and their location (city).?
3. How would the structural integrity be satisfied?
4. After incorporating such structural integrity measures, how does the cost of such a precst struture compare with the cost of a cast-in-place concrete of the same size? The same, less or more?
5. If you had the choice, would you recommend that such a multistorey garage be precast or cast-in-place?
I realize thar there are many factors that must be considered when selecting precast vs cast-in-place for any given parking structure (such as the durability requiremenrs given in CSA Standard S413 Parking Structures, with which I am thoroughly familiar, having designed a number of large cast-in-place garages over many years), but if the answers to the foregoing can be suggested, it would be helpful, as a starter. Note that I would likely consider most cast-in-place parking strutures to have inherent structural integrity, without any very significant additional provisions.
Thanks
