Recently we added a support beam and new support wall in basement due to sagging floor trusses and lots of vibration when walking and jumping. We also added some Hvac to the room, they ended up cutting our strongback lateral support 2x6 board. Shortly after we did that, we felt constant floor tremors. We are hoping we did not damage our truss supports. The floor is much stronger now but any guidance on the tremors would be appreciated.
