A-j is the distance from the end of the wall to the nearer edge of the bearing area of the concentrated load (see Figure 4.6) H is the height to the level of the load (see Figure 4.6). Figure 4.6 Concentrated load in relation to a and H - the bearing area under the concentrated load neither exceeds 4 of the cross sectional area of the wall nor exceeds the value 2 , where t is the thickness of the wall - the eccentricity of the load from the centre plane of the wall is not greater than t 4 - the...
