  3. Definition LINTEL POSTS Post and lintel isone of themostbasic and simple constructiontechnique. Itconsist in an horizontal member, commonlyknown as lintel, supportedbytwo vertical post oneachend.

  4. Evolution Stone Age Basic post and lintel construction, but gigantic in size of construction members. The sides are vertical slabs of stone, capped with horizontals. Stonehenge

  5. Evolution SumerianCivilization Post and lintel were use as thefirststructuralsystem , thewallthatthe lintel supportedwasconstructedwithbricks. Sumeriansweretheonesthatcreatedthefirstbuildingsupportedwith a post and lintel and withbrickwalls.

  6. Evolution Egiptians Karnak, Egipt

  7. Evolution Greeks Post and lintel, it was the first way to support the roofs of temples and buildings. I consist on two posts supporting a lintel with nothing in between. Parthenon was the maximum width that the number of pillars could support without collapsing, or else they’d have to put more pillars inside.

  8. Evolution Romans Romans brought the concept of post and lintels to a new level with the creation of the arch, which could support more weight than the structures of the Greeks and provided greater stability to their buildings. Also they introduce buttresses to the structure to hold up massive cathedral walls.

  9. Evolution Also post and lintels are found in the construction of bridges, complex archways and pergolas. Modern Uses Now the wall is an important complement of the post and lintel work, because it adds more support for the construction and also hides the post and lintel design within the framework.

  10. Evolution

  11. How the Post and Lintel structure supports loads? The lintel must bear loads to the posts. The Posts support the loads that the lintel receives and support the weight of the lintel.

  12. Propper materials for Post and lintel • Brick • Stone • Wood • Steel • Reinforced Concrete

  13. Weak on tensile strenght Strong on compression Easy to find and cheap Masonry construction For Lintel: For Post: System: Propper materials for Post and lintel: Brick

  14. For Lintel: For Column: System Propper materials for Post and lintel: Wood Characteristics: Good on tensile strength Bad on compression Strong material Not buckling

  15. Characteristics: Weak on tensile, stong on compression Stronge material Expensive and difficult to transport. For Lintel: For Post: System: Propper materials for Post and lintel: Stone

  16. Good on tensile Not so good on compression Can give long distance on structures. For Lintel: For Post: System Propper materials for Post and lintel: Steel

  17. Good on compression and tensile strenght A combination of materials: Concrete and Steel For Lintel: For Post: System Propper materials for Post and lintel: Reinforced Concrete

  18. Examples of Post and Lintel • On ancient architecture

  19. Examples of Post and Lintel • On Buildings

  20. Examples of Post and Lintel • On Bridges

  21. Examples of Post and Lintel Everything that needs structure!

  22. Conclussion • Post and lintel is the oldest structure built by men • A basic structure • It has evolved to become the great structures we have nowadays. • There are more suitable materials for post and lintel structures • It can be used on any kind of construction
