Transcribed Image Text:**Problem 44**: An L4×3×3/4 is attached to a gusset plate with three 3/4 in. bolts spaced at 3 in., with an end and edge distance of 1.5 in. as shown in Figure P4.44. Determine the available block shear strength of the A36 angle by (a) LRFD and (b) ASD.
**Figure P4.44 Description**:
The figure illustrates an L-shaped angle iron attached to a gusset plate. There are three labeled circular holes representing bolts. The dimensions include:
- Vertical dimension from the top to bottom of the angle is 3 in.
- Horizontal length between the centers of the bolt holes is 3 in. each.
- End and edge distances from the bolt center to the edge are 1.5 in.
- The height from the top edge of the L-shape to the first bolt hole is 1.5 in.
This setup is used to calculate the block shear strength of an A36 steel angle using two methods: Load and Resistance Factor Design (LRFD) and Allowable Stress Design (ASD).
