Q1) Choose the correct answer: 1- Rankine's theory of earth pressure neglect: The pressure on the wall is to act parallel to the surface of the soil at angle (B) to the horizontal. The effect of cohesion on active and passive pressure. The friction developed between a retaining wall and the soil. o The depth of tension zone. o The effect of water table. 2- The lateral earth pressure is the lateral pressure that developed from: o Water beside it. o Soil beside structure. o External loads. o All the above. o Excavation beside structure. 3- The coefficient of earth pressure at rest represented as o Ko-1-sing expression given by Jaky. o Ko-sing 。 Ko-1-cosp о o Ko-cosp 。 Ko" tano 4- If the backfill carries a uniform surcharge q, then the lateral pressure at the depth of wall His: o pa-Ka yz+Ka q o pa Ka yz-Ka q o pa Ka yz*Ka q o pa Ka yz/Ka q 。 pa=Ka yz+q 5- During the active state of plastic equilibrium, the retaining wall moves: o Towards the fill o Away from the fill o Does not change…

A 8.5 meter simply supported reinforced concrete beam on parallel rectangular column, where the column width is 300 mm is shown in Figure carries a uniformly distributed variable action of 10 kN/m and permanent action of 9 kN/m (including self-weight of beam). The clear cover of beam for class XC-1 is 25 mm, diameter of main and shear reinforcement are 20 mm and 8 mm respectively. The characteristic material strengths are fck = 30 N/mm² and fyk = 500 N/mm². Apply variable Strut Inclination Method to design the shear reinforcement (links) for the beam. h = 370 mm 마 *b = 230 mm Section A-A
