| description | In this study, a simple computer program are written using FOTRAN 90 to
investigate the behavior of simply supported beam constructed with straight tendon
which are subjected to three different load cases. Considering the same stresses
applied, beam subjected to loading at one third span shows a less deflection than
other load cases. Behavior due to the deflection of bonded tendon gave better
performance than unbonded tendon. However, beams with larger span-to-depth ratio
would require deviators in case of external prestressing to achieve the desired
performance. Parabolic and trapezoidal tendon allows the prestressed beam to carry
heavier loads because of the balancing effects of the vertical component of the
prestressing deflected tendon. Hence it will required less prestressing force at the
mid span compared with the force required in the straight tendon. |
