The plane frame below is analyzed by neglecting axial deformations. Following statements are made with respect to the analysis
I. Column AB carries axial force only
II. Vertical deflection at the centre of beam BC is 1 mm

With reference to the above statements, which of the following applies?
EI = 81380 kN-m²

1. Both the statements are true
2. Statement I is true but II is false
3. Statement II is true but I is false
4. Both the statements are false

Correct Option: A

Since there are no horizontal loads, the columns are subjected to axial loads only.
Deflection at centre

=	5WL⁴	=	5 × 10 × 5⁴	= 1 mm
	384EI		384.813
