ZIBI Block 11

 

Project description

A reinforced concrete building with 12 floors plus 3 underground parking levels in the heart of the Zibi project in Gatineau / Ottawa.  A total of 148 residential units, 3 commercial units on the grouund floor, and parking for 181 vehicles.  The building is connected to a central district-thermal energy system which takes energy from the Kruger paper mill.

 

Inspiration

The Canadian standard for reinforced concrete buildings requires a lot of checks for behaviour during major earthquakes.
 
Structural engineering software doesn’t account for all these checks, so we created three structural models to tackle the problem, along with a lot of specialised Excel spreadsheet development.
 
  • To check the floors, columns, and load-bearing walls under gravitational loads, including snow accumulations in multiple places.
  • To check the shear walls under wind and extreme seismic loads, with a recurrence of once every 2,500 years.
  • To check the robustness of the columns to wothstand the large lateral deformation of the floors during an extreme earthquake.
 
In fact, the seismic recurrence is calculated for a 2% probability over a 50-year period.
 
But with the help of our concrete guru, we managed to save 70 tons of rebar compared to the budget—much to the delight of our impressed client!
