Question

A rectangular beam 200 mm x400 mm spans over 10m and carries an imposed load of 5 kN/m. if the force of pre-stressing is 500 kN and tendons are centred at100 mm from the bottom, compute the stresses in beam using the load balancing concept. Assume prestress tendons are parabolically draped.​

Answer 1

Answer:

• Draw a free body diagram for this concept you might get the answer.
• If prestress tendons parabolically dropped it might be 2 D motion.
