Figure 4.2.3-6: Bending moment envelopes Figure 4.2.3-6: Bending moment envelopes The most unfavourable bending moments are equal to: x direction: Mx=12.3 (10.8) [*] NoteThe respective results corresponding to global loading are shown in brackets. , Mx,erm=-22.8 (-22.0) [kNm] y direction: My=4.9 (4.1), My,erm=-18.8 (-16.3) [kNm] Figure 4.2.3-7: Front view of 3D bending moment diagrams, corresponding to the envelope of [Mx] Figure 4.2.3-7: Front view of 3D bending moment diagrams, corresponding to the envelope of [Mx] Figure 4.2.3-8: Side view of 3D bending moment diagrams, corresponding to the envelope of [My] Figure 4.2.3-8: Side view of 3D bending moment diagrams, corresponding to the envelope of [My] Note that although the live load has a relatively high value, the differences between the bending moments are small and less than15%. Figure 4.2.3-9: Deflection envelopes Figure 4.2.3-9: Deflection envelopes The largest slab deflection is equal to y=-2.00 (-1.53) [*] NoteThe respective results corresponding to global loading are shown in brackets. mm and y=+0.24 mm. It is concluded that the slab is lifted, which is in contrast with the responseof the global loading case, due to symmetry of course.
