yields the required new nodal displacements, namely, mi = —5.22 mm and v\ = —10.58 mm.

Example 9.3

A steel beam is supported and loaded as shown in Fig. 9.36. The relevant second moments of area are such that I(a) = 21<h) = 2 x 10~5 m4 and Young's modulus E for the beam material = 200 GN/m2. Using the displacement based finite element method and representing each member by a simple beam element:

50 kN.m
