CE 355 Structural Analysis Fall 2014

Instructor: Serdar Soyöz

1. Determine the stiffness matrix K for the truss.

Then, determine the force in member 5 . Take A

= 0.0015 m^2 and E = 200 GPa for each

member. (You can use Matlab)

(Ans: q5=33.3kN )

2. Determine the reactions at the supports. EI is

constant.

(Ans: R5=7.50 kN, R6=15 kN, R6=60 kN.m)
