All the above.<\/p>\n<p>The assumptions for the design of a pre-stressed concrete member are:<\/p>\n<ul>\n<li>A transverse plane section remains a plane after bending. This is known as the Bernoulli hypothesis. It states that the plane sections of a beam before bending remain plane after bending. This assumption is valid for small deformations.<\/li>\n<li>During deformation limits, Hook&#8217;s law is equally applicable to concrete as well as to steel.
