EXTERNAL STABILITY STABILITY CHECK : OK

ANALYSIS - Assumptions & Notes

1) Wall idealised as a propped cantilever ( i.e. pinned at top and fixed at base )2) Wall is braced.3) Maximum slenderness of wall is limited to 15, i.e [ 0.9*(He-Tb/2)/Tw < 15 ]4) Maximum Ultimate axial load on wall is limited to 0.1fcu times the wall cross-sectional area5) Design Span (Effective wall height) = He - (Tb/2)

7) " Wall MT. " is maximum +ve moment on the wall.
