A footbridge illustrated below has a spanning 12 m across a river. All the members, except those in the lateral bracing, are 3 m long and the walkway is 2 m wide. An estimated weight for the bridge itself is 35 kN and the required characteristic imposed load is 4 kN/m2. Partial safety factors of 1.4 on dead load and 1.6 is on imposed load should be used. Compute the force at member CD (kN).
