A relatively new apartment building in St. Kilda has been madewith complex architectural balconies.
The balcony railings have been fabricated from an extruded6000-series (Al-Mg-Si) aluminium alloy.
The balcony railings have been fixed to mild steel posts usingstainless steel screws. The construction
team did not use rubber washers in any instance.
Briefly describe what you think may occur in such a situation underatmospheric conditions.
Also, what do you think may occur if galvanised steel screws wereused instead of stainless steel?
Finally, what would you have done differently, if you were thechief engineer for the project?
