1. Structural Analysis-I Dr. Ali Tayeh Second Semester 2010-2011

2. Lecture 13 Cables & Arches

3. Cables Cables are often used in engineering structure to support and or transmit loads from one member to another

5. Cables subjected to concentrated loads

6. Example 1 Determine the tension in cables and what is the dimension h ?

13. Cables subjected to a Uniform Distributed Load

14. Analysis Procedure

15. 1

16. General Case

17. Note

18. Example 2 Determine the tension of the cable at points A, B, C

22. Example 3 Determine the tension of the cable at points A, B

23. Arches

24. Arches Types

26. Three hinge frame

27. Example 1 Determine the internal forces at Section D

28. 242 86 cos20 93 sin20 86 86 sin20 93 93 cos20 242 112.6 58

29. Example 1 Determine the internal forces at Section D

33. Example Determine the reactions for the arch Determine the internal forces at point E

34. Solution:

36. Internal Forces:

37. We will find the shear and the normal forces just before and just after E

38. Group Work 1 Determine the internal forces at B
