For the retaining wall below calculate the foundation dimension (W)so that safety is satisfied. Unit weigth of soil 18kN/m³ and unit weigth of concrete 25 kN/m³ O'=30 degrees (Factor of Safety:3) UDL Surcharge 0.2m H (m) 15 UDL 15 (kN/m2) H

Assignment 5: A rectangular brick pool was constructed using MU10 brick and M10 cement mortar with a thickness of 620mm. The construction quality control level is grade B. If the vertical stress caused by the self-weight of the pool wall is not considered. Water pressure can be considered as variable load. What's the design value of maximum water pressure height H? f. = 0.17MPA f, = 0.17MPA P = pH

Q4) A 400 square column carries dead load of 1050 kN and imposed load of 300 kN as shown in figure Q4. The safe bearing capacity of soil is 170 kN/m². By using following design data: Design data: The characteristic strength of reinforcement steel (f) = 500 N/mm? The characteristic strength of concrete is (feu) = 35 N/mm?. Over all depth of foundation 600 mm Diameter of tension reinforcement is 20 mm, Density of concrete is 24 kN/m3 Concrete cover 50 mm Design size of square footing Design of bending reinforcement iii. Check punching shear, face shear, i. ii. footing against = 1050 kN imposed = 300 kN Axial loads: dead Figure Q4

Based on the figure shown below determine the width of the ?footing (B) in (meter) F2 F1 3.5 m 0.8 m Use: F1= 1,725 N; F2= 1,028 N; and allawable stress for soil = 173 N/m2
