A 200mm thick brick masonry wall made of modular bricks carries an axial load of 30KN/m from wall above and an eccentric load of 20KN/m from RCC floor acting at a distance of 47.5mm from centre line of the wall. The resultant eccentricity ratio is

Detailed Solution:

Thickness of wall=200mm ,e1=47.5mm Let w1=30KN/m, w2=20KN/m Let the resultant load w is acting at resultant eccentricity e which is equal to , e= (w1x0+w2xe1)/(w1+w2) =(30x0+20x47.5)/(30+20) = 19, Hence Resultant eccentricity ratio = e/thickness of wall Therefore resultant eccentricity ratio=19/200 =0.095
