Q.1(a) shows a pinned supported frame with hinge at B is subjected to the point load 10 kN perpendicular to the mid-span of column AB and parabolic distributed load of w = x2 kN/m on beam BC.
(a) Determine the support reactions at A and C.
(b) By considering the beam BC, show that the moment at any point between BC as
a function of x (x is the distance of any section in BC from point C, shown in the
figure above) is ? = (6.75? −
(c) Using the method of section, calculate and draw the axial force, shear force and
bending moment for the structure and mark the values of axial force, shear force
and bending moment at key points.
