Post+and+lintel+Presentation

- The post and **lintel** system is composed by two **upright** members (post, columns…) and a third member (lintel, beam…) above the last two.

- This system is the base for the evolution of openings and for support of the weight located above openings.

Lintel: - bear the loads that rest on it without breaking - It can fail when the material is too weak or lintel too long - Materials: wood, stone (short ones), steel (bigger spans), reinforce concrete

Post: - Support the lintel and its loads à transition of the loads from the lintel to the earth - Masonry and brick à good material (cohesiveness)

Disadvantages: -The limited weight it can hold up and the short distances needed between each post. - The tension produced by the self-weight

Example of post and lintel system: //Stonehenge//

- Lintels need to be strong in bending

- Posts need to be strong in compression
