  1. For reinforced concrete vertical column, with hinge ends, is applied with end moments and lateral load as shown in the figure. Column high is 10 ft . The shear force at mid-height of the column ( 5 ft from column end ) according to applied loads will be almost equal to _____. Neglect own weight of the column. (a) 5.0 kips (b) 4.0 kips (c) 2.0 kips (d) 8.0 kips Ans: ∑ moment at B = 0 R AX × 10 + 20 + 20 = 1 × 10 × 5  R AX = 1 kip R BX = ( 1× 10 ) - 1 = 9 kip Shear force at mid-height of the column V mid = 9 - ( 1 × 5 ) = 4 kip     [ → ]           (b)
