kip-ft. For Beam 4, kip-ft. Beam No.5. Compute the depth of the equivalent rectangular stress block,, assuming that tension steel is yielding. in. For psi, . Therefore, in. Thus, > 0.002 and the steel is yielding (). Since, the section is clearly tension-controlled and =0.9. kip-ft. For Beam 5, kip-ft ................
