1. A simply supported prismatic concrete beam of rectangular cross-section, having a span of 8 m, is prestressed with an effective prestressing force of 600 kN. The eccentricity of the prestressing tendon is zero at supports and varies linearly to a value of e at the mid-span. In order to balance an external concentrated load of 12 kN applied at the mid-span, find the required value of e. Span of the beam, L = 8m Effective prestressing force, P = 600kN Concentrated load at midspan, W = 12kN Eccentricity of tension at midspan, e = ?

1. A simply supported prismatic concrete beam of rectangular cross-section, having a span of 8
m, is prestressed with an effective prestressing force of 600 kN. The eccentricity of the
prestressing tendon is zero at supports and varies linearly to a value of e at the mid-span. In
order to balance an external concentrated load of 12 kN applied at the mid-span, find the
required value of e.
Span of the beam, L = 8m
Effective prestressing force, P = 600kN
Concentrated load at midspan, W = 12kN
Eccentricity of tension at midspan, e = ?
