Structural Analysis: Nuclear Quiz 2

A fixed beam AB with a central hinge ‘C’ is built up of two components. Member AC has infinite flexural rigidity and CB has moment of inertia I. If the support A yields and rotates by θ, what will be the moment at B?

Distributed load (s) of 50 kN/m may occupy any position(s) (either continuously or in patches) on the girder PQRST as shown in the figure (not drawn to the scale)

The maximum negative (hogging) bending moment (in kN.m) that occurs at point R, is

The force in the member ‘X’ of the truss supported and loaded as shown is

A frame EFG is shown in the figure. All members are prismatic and have equal flexural rigidity. The member FG carries a uniformly distributed load w per unit length. Axial deformation of any member is neglected.

Considering the join F being rigid, the support reaction at G is

A three hinged symmetric parabolic arch of span 20 meters and rise 5 meters is hinged at the crown and springing. It supports a uniformly
distributed load of 2 tonnes per meter run of the span. The horizontal thrust in tonnes at each of the springing

A simply supported beam has a span of 15 m. UDL of 40 kN/m and 5 m long crosses the girder from left to right. Using influence line diagram, the maximum bending moment, at a section 6 m from left end, is
