Question

Transcribed Image Text:**Problem 45:**
A 7×3/4 in. A36 plate is shown in Figure P4.45, where the holes are for 3/4 in. bolts. Determine the available block shear strength by (a) Load and Resistance Factor Design (LRFD) and (b) Allowable Stress Design (ASD).
**Diagram Explanation:**
The figure depicts a rectangular plate with six circular holes arranged in two rows of three. The plate dimensions and hole placements are as follows:
- Vertical spacing between holes in each column: 1 1/2 inches
- Total vertical distance of holes: 4 inches centered about the plate's height
- Horizontal spacing between holes in each row: 3 inches
- Horizontal edge distance from the first/last hole to the plate edge: 1 1/4 inches
Figure P4.45 provides a schematic layout for the problem, illustrating the positioning and size of bolt holes needed for block shear strength analysis.
