**Problem 9-4:** Compute the maximum spacing of No. 5 bars in a one-way slab with 1 inch of clear cover that will satisfy the ACI Code crack-control provisions (Section 24.3.2).Given: \( f_y = 60 \, \text{ksi} \).### Explanation:This problem involves calculating the appropriate spacing for reinforcing bars in a concrete slab to comply with the American Concrete Institute (ACI) Code, specifically targeting crack-control measures. The given data points include:- The use of No. 5 bars, which have a specific diameter and area.- A clear cover of 1 inch, which refers to the distance between the outer surface of the concrete to the surface of the reinforcing steel.- The yield strength of the steel, \( f_y \), is specified as 60 ksi (kips per square inch).This ensures the structural integrity and durability of the slab by preventing excessive cracking. The guidelines followed are from the ACI Code, Section 24.3.2, which provides standards for crack control.

Masonry wall construction

Masonry walls of various sorts are utilized in building construction. Masonry walls are the most enduring feature of any structure or building. It separates a structure from the outside world. In masonry construction, the common masonry materials used are building stone, brick, cast stone, glass block, and concrete block. Masonry construction is a type of construction that has the highest durability.

Question

**Problem 9-4:** Compute the maximum spacing of No. 5 bars in a one-way slab with 1 inch of clear cover that will satisfy the ACI Code crack-control provisions (Section 24.3.2).

Given: \( f_y = 60 \, \text{ksi} \).

### Explanation:

This problem involves calculating the appropriate spacing for reinforcing bars in a concrete slab to comply with the American Concrete Institute (ACI) Code, specifically targeting crack-control measures. The given data points include:

- The use of No. 5 bars, which have a specific diameter and area.
- A clear cover of 1 inch, which refers to the distance between the outer surface of the concrete to the surface of the reinforcing steel.
- The yield strength of the steel, \( f_y \), is specified as 60 ksi (kips per square inch).

This ensures the structural integrity and durability of the slab by preventing excessive cracking. The guidelines followed are from the ACI Code, Section 24.3.2, which provides standards for crack control.
