Consider the simply supported T beam shown below. Calculate: • The instantaneous deflection (camber) at transfer of prestress • The deflection under service loads • The additional long-term deflection under dead load and prestress using the heuristic rule (rule of thumb) The total deflection including long-term deflection Given: O A = 272 in.² o fpu = 270 ksi o fpe = 150 ksi o I = 14,970 in. oyt = 9.06 in.
