2. What is truss? A framework composed of members joined at their ends to form a rigid structure, built from basic triangles in the manner described is known as truss or simple truss.

3. Types of trusses Trusses can be mainly divided into two types: Bridge Trusses. Roof Trusses .

4. Types of bridge trusses PRATT BRIDGE TRUSS HOWE BRIDGE TRUSS BALTIMORE BRIDGE TRUSS K BRIDGE TRUSS WARREN BRIDGE TRUSS BAILEY BRIDGE TRUSS .

5. It includes vertical members and diagonals that slope down towards the center. PRATT BRIDGE TRUSS

6. HOWE BRIDGE TRUSS It includes vertical members and diagonals that slope up towards the center .

7. A Baltimore truss has additional bracing in the lower section of the truss to prevent buckling in the compression members and to control deflection BALTIMORE BRIDGE TRUSS

8. K-BRIDGE TRUSS A truss in the form of a K due to the orientation of the vertical member and two oblique members in each panel is known as a K bridge truss.

9. PICTURE OF K-BRIDGE TRUSS

10. It consists of longitudinal members joined only by angled cross-members, forming alternately inverted equilateral triangle-shaped spaces along its length. WARREN BRIDGE TRUSS

11. It is designed for military use, the prefabricated and standardized truss elements may be easily combined in various configurations to adapt to the needs. BAILEY BRIDGE TRUSS

12. ROOF BRIDGE TRUSSES PRATT ROOF TRUSS FINK ROOF TRUSS HOWE ROOF TRUSS WARREN ROOF TRUSS KING POST ROOF

13. It uses vertical member for compression and horizontal members to respond to tension and is most efficient under static and vertical loading. PRATT ROOF TRUSS

14. They are used for longer spans having high pitch roof, since the web members in such truss are sub-divided to obtain shorter members FINK ROOF TRUSS

15. It is a roof truss with vertical web members to take tension forces and with angled braces to take compression HOWE ROOF TRUSS

16. In warren roof truss diagonal members are alternatively in tension and compression and are used in a building ranging from 20-100m in length. WARREN ROOF TRUSS

17. A king post extends vertically from a crossbeam to the apex of a triangular truss. It connects the apex of the truss with its base, holding up the tie beam (in tension) at the base of the truss . FINK HOWE ROOF TRUSS
