Q2
Figure shows a structure loaded with vertical load of 40 kN at joint C, horizontal
Load of 20 kN at joint C and 30 kN at joint E. The structure is supported by a
roller at joint A and pinned at joint F.
(а)
Determine the determinacy of the structure.
(b)
Calculate all Reaction Forces at each support.
(c)
Calculate and sketch the Internal Force due to External Force for each
element of the structure.
Assume the AE value is coherent or same at all elements and the given value is
AE = 80 x 10 kN. Using Method of Virtual Work, fill in the value in the table and
determine the following terms,
(d)
Horizontal displacement of joint C if 1 Unit Load in horizontal direction is
applied at the joint.
(e)
Calculate and sketch the internal force due to the Unit Load at joint C.
Vertical displacement of joint D if 1 Unit Load in vertical direction is
applied at the joint.
(f)
(3)
Calculate and sketch the internal force due to the Unit Load at joint D.
