Temp changes
Cards in this deck (7)
- 1What is the effect of an increase of temperature in a member?Increase of Temp (ΔT) causes expansion and the member length increases by ΔL. Resulting in additional Fixed End Forces at joints
- 2Change in length from Temp change?ΔL=αΔT*L
Temp change * coefficient expansion * member Length - 3What are Fixed End ForcesReactions generated at fixed ends
- 4What is the effect of a member fabricated too long?Causes increased stress at the joints as it is in compression
- 5Degree of Indeterminacy...? Why?r-3b=(2*4)-(3*3)=1
Indet. to 1st deg
2 reactions at each node.. - 6Gpa in KN/m21x10^6
Pa (N/m2) -> Mpa (kN/m2) - 7—
