Hi there,
I'm working on a project where the client intends to install quite a large window(5x5'), which will take up most of an external wall. They've started construction already but wanted me to do a quick check.
I want to make sure that the corner wall nibs can take the wind loads that get transferred from the window and I want to make sure that I'm going about it the right way.
See the attached calculations :
These are very basic but I assume quite conservative, as I have assumed that the nib is pinned top and bottom and I haven't considered the additional deadload on the corner nib from the 6" concrete slab above, which should increase the nibs bending capacity. Based on the calcs is this the right approach for checking the nib or should I be taking a different approach?
Is there anything else critical that should be checked in a configuration like this? The corner nib CMU block cells will be filled with concrete (no steel reinforcement). There will be a 6" concrete floor resting on top of the walls, which will tie all of the walls together.
