Q2/ Determine the short-term deflection due to dead and live loads and 4-year long-
term deflection at the free end of the cantilever beam shown in Figure 1. Beam weight
is included in the wp value. Also, investigate the beam deflection against ACI
requirements assuming the beam supports non-structural elements not likely to be
damaged by large deflections.
f=4000 psi, fy = 60000 psi.
