1 Answer

Answer :

i) Eccentric straight cable profile: The stress due to prestressing alone are generally combined stresses due to the action of direct load bending from an eccentrically applied load. In this case, the load is applied concentrically and a compressive stress of magnitude (P/A) will act through out the section. Thus the stress will generate in the section as shown in the figure below.
