Question 4 ( 25 marks) The two-span continuous beam \( \mathrm{ABC} \) in Figure \( \mathrm{Q} 4 \) carries uniformly distributed and concentrated loadings as shown. Considering supports \( \mathrm{B} \) and \( \mathrm{C} \) as redundant, a. determine the deflections at points \( B \) and \( C \) of the primary structure by any known deflection method (9 marks) b. determine the deflections at points \( B \) and \( C \) of the redundant structure by any known deflection method (8marks) c. Write out the compatibility equation and determine the unknown reactive forces at points \( \mathrm{B} \) and \( \mathrm{C} \) respectively (5 marks) d. determine the vertical reaction and moment at point \( \mathrm{A} \).
