SAUDI BUILDING CODES

The first option concerns the topology of the soil . There are 5 options: • Two-dimensional ridges • Two-dimensional fronts • Three-dimensional axisymmetric hill • Flat, unobstructed areas and water surfaces • Choice of user The third option sets a value for the coefficient Kzt=1. The fourth option involves the input of a Kzt value by the designer. The next option concerns whether the place where the structure is located is downwind (Windward, Upwind) or Leeward (Downwind) . The next three options They concern data on the topography of the area Lh: proximal distance (in metres) of the summit where the difference in ground elevation is equal to half the height of the hill or front H: Height of the hill or front (in metres) in relation to the leeward side of the ground. x: Leeward or downwind distance of the top (in metres) as in figure 6.4-2. In the next parameter the type of building is selected based on the stiffness of the bulkheads. There are three options: • Rigid • Flexible • Parapets In case the construction type is set to Flexible, the following two parameters must be set:
