Hi. I need help calculated the tension on bolts in an anchor plate.
The plate is bolted to a concrete wall with four bolts (see the included image). A bending moment acts on the plate, offset a bit up/down. The bending moment acts from up to down so that the upper two bolts are in tension and concrete under the lower part is in compression.
I would like to know how to calculate the tension induced on the upper two bolts by this bending moment.

In case the image link isn't working:
Bending moment: M
Plate width: w
Plate height: h
Horizontal distance between bolts: a
Vertical distance between bolts: b
Distance from lower bolts to the horizontal axis that the bending moment bends around: d
Thanks.
