Use Moment Area to find the slope at B and the deflection at

Use Moment Area to find the slope at B and the deflection at D for the following frame. The frame has a constant EI. 3 k/ft 6 k 14\' 18\' 4\' 6 k 12\' 27 k

Solution

slope at joint B = area of M/(EI) diagram between A and B

BM at B = 6*18 =108

slope at B = area of triangle

= (0.5*18*108)/(EI)

= 972/(EI)

deflection at D = 0 ( it is support )
