Thank you for the reply I will look into the Allan block for tiered walls, I think they like the look of concrete walls. I’ll look into the raking active wedge to get a less conservative angle. Much appreciated
Thanks for your input it’s helpful. The wall system is in the design phase and they are open to any modifications to make structural work, but of course keeping cost in mind. The higher wall ideally they would like to only have the footing down 4ft which is frost depth here, but can extend...
Hello All,
looking for some engineering expertise on cantilever retaining wall with possible inclined backfill slope (still verifying with the architect that his drawings have a slope, most likely it does)
Question: how would you guys approach designing the two tier cantilever wall approach...
Thank you for your reply, yes they have projects in BC too where they provide schedule B and then the schedule C. I am very curious how they are by-passing the field reviews requirements….
I guess my question is how do engineers ensure compliance with their structural drawings for a project they designed for a location too far away for in person inspections? I highly doubt this outfit is flying across Canada to do even one site inspection on a residential home design.
For the Structural Engineers out there,
when you do projects that are out of town and in another province how do you do your site reviews to ensure compliance to your drawings? Reason I ask is because I know an outfit here in Canada thats doing projects all around Canada and there is no way...
Hello all,
looking for some advice on a project that just came up using the hambro floor system in a 2 story residential home. Contractor wants to add a home lift (elevator) starting on the main-floor up through the second floor (require coring through the 3" concrete composite slab). The lift...
if the cantilever wall is only required to be designed for the 0.5kpa (factored load) as per my attachment from the NBCC commentaries. Then I believe a 8" wall cantilevered is still sufficient (although it might not stay plumb), as my seismic load does not exceed the 0.5kpa (low seismic area)...
Hi BA,
my understanding is that if you laterally support your firewall on both sides of the structure, and if one side of the structure collapses due to the fire then the remaining undamaged side of the building is providing lateral support to the firewall, and also some lateral load due to the...
Hello all,
I have been requested by the architect to provide a detail for a concrete fire wall that spans about 37' ft above slab on grade (43' to top of footing)
This will be a non-load bearing wall in terms of gravity loading and will not be connected to adjacent structure on either side...
