Question 1 - Reinforced Concrete Walls (20 Marks) The rectangular reinforced concrete wall section shown in the Figure for Question 1 has a length of 2500 mm and a thickness of 175 mm. The vertical reinforcement in the web region of the wall consists of a single layer of HD12 at 200mm centres. The wall has been designed for a nominally ductile response (u = 1.25) and with a specified concrete strength of f. = 40 MPa (Precast). The design factored axial load (excluding self-weight) is N* = 200 kN and the horizontal force acting on the top of the wall is 120Kn (a) Check if the wall section satisfies the minimum vertical reinforcement requirements. [5M] (b) Calculate the nominal flexural capacity of the wall section for in-plane loading.
