  2. 2. 3. THE STRUCTURE <ul><li>3.1. Structural Requirements </li></ul><ul><li>3.2. Structure Types </li></ul><ul><li>3.2.1. Post and Beam Structures </li></ul><ul><li>3.2.2. Arches and Vaulted Halls, and Domes </li></ul><ul><li>3.2.3. Portal Frames </li></ul><ul><li>3.2.4. Trusses </li></ul><ul><li>3.2.5. Space Frames </li></ul><ul><li>3.2.6. Folded Roofs </li></ul><ul><li>3.2.7. Shells </li></ul><ul><li>3.2.8. Tensile Structures </li></ul><ul><li>3.3. DETERMINATION OF THE STRUCTURAL FORM </li></ul><ul><li>3.3.1. Design Strategies </li></ul><ul><li>3.3.2. Selection Of The Generic Type Of Structure </li></ul><ul><li>3.3.3. Selection Of Structural Material </li></ul>
  3. 3. 3. The Structure 3.1. STRUCTURAL REQUIREMENTS <ul><li>DURABILITY </li></ul><ul><li>The durability of the structure depends entirely in the physical/chemical conditions </li></ul><ul><li>of the structural material, and our willingness to continue using the building ( at the </li></ul><ul><li>end of the lifecycle of a building, it may be demolished) </li></ul><ul><li>STABILITY AND EQUILLIBRIUM </li></ul><ul><li>When the structure is stable and in equilibrium it resists any load without suffering </li></ul><ul><li>a major change of shape or collapsing. </li></ul><ul><li>STRENGTH AND RIGIDITY </li></ul><ul><li>Strength and rigidity are reached by the adequate specification of geometry, size, </li></ul><ul><li>and the material of the structural elements. In example, for resisting the same </li></ul><ul><li>structural load , a steel structural element needs a smaller cross section than a </li></ul><ul><li>reinforced concrete element, and this is due to the difference between the </li></ul><ul><li>strength of the kind of materials. </li></ul>

  10. 10. 3. The Structure 3.2. Structure Types 3.2.1. POST AND BEAM STRUCTURES <ul><ul><ul><li>Most architectural structures are of the post-and-beam type. </li></ul></ul></ul><ul><ul><ul><li>Post and beam buildings carry the weight of their structural components </li></ul></ul></ul><ul><ul><ul><li>(and the weight of objects and people in them) by bearing on one another. </li></ul></ul></ul><ul><ul><ul><li>The weight of the roof and beams is carried by the posts down to the foundation </li></ul></ul></ul><ul><ul><ul><li>and then into the ground. Horizontal beams are subject to bending loads, </li></ul></ul></ul><ul><ul><ul><li>therefore the structural materials should be able of resisting both tension and </li></ul></ul></ul><ul><ul><ul><li>compression. </li></ul></ul></ul><ul><ul><ul><li>We can further subdivide the post and beam structures into: </li></ul></ul></ul>
