A simply-supported T-beam is subjected to two pairs of distributed loads: pair 1 (W_D1, W_L1) and pair 2 (W_D2, W_L2). The geometric, material and loading properties are all given on the table above. 1. Solve for the height of the compression stress block using pair 1.  2. Solve for the theoretical steel area using pair 1.  3. Using Es = 0.004, solve for the theoretical steel area using pair 2.  4. Using Es = 0.005, solve for the theoretical steel area using pair 2.

PROBLEM: 
A simply-supported T-beam is subjected to two pairs of distributed loads: pair 1 (W_D1, W_L1)
and pair 2 (W_D2, W_L2). The geometric, material and loading properties are all given on the
table above.


1. Solve for the height of the compression stress block using pair 1. 
2. Solve for the theoretical steel area using pair 1. 
3. Using Es = 0.004, solve for the theoretical steel area using pair 2. 
4. Using Es = 0.005, solve for the theoretical steel area using pair 2.
