C Type WindpostsSectional properties and loading data for C type windposts.  C type windposts are designed within the cavity and eliminate the need for cutting blockwork. The posts are bolted to the structure with suitable fixings. The use of WPT1 clip on ties to both the external & internal leaf transfer the loadings applied to the cladding back to the structure.
The following tables illustrate the typical sizes available; however, almost any size can be designed / manufactured.  C Type Windposts:Windposts are designed as simply supported beams. Maximum deflection is height/360 and maximum stress is 195N/mm². | Section | Ixx | Zxx | 2.5m | 3.0m | 3.5m | 4.0m | 4.5m | 5.0m | 5.5m | 6.0m | | a x b x t | cm 4 | cm³ | Maximum unfactored load fo height of windpost (UDL) kN | | 55x60x4 | 34.74 | 12.63 | 2.4 | 1.7 | 1.2 | 0.9 | ~ | ~ | ~ | ~ | | 55x60x5 | 41.42 | 15.06 | 2.8 | 2.0 | 1.4 | 1.1 | ~ | ~ | ~ | ~ | | 65x60x4 | 50.89 | 15.66 | 3.5 | 2.4 | 1.8 | 1.4 | 1.1 | ~ | ~ | ~ | | 65x60x5 | 61.06 | 18.79 | 4.2 | 2.9 | 2.1 | 1.6 | 1.3 | 1.0 | ~ | ~ | | 75x60x4 | 70.58 | 18.82 | 4.8 | 3.3 | 2.5 | 1.9 | 1.5 | 1.2 | 1.0 | ~ | | 75x60x5 | 85.07 | 22.68 | 5.8 | 4.0 | 3.0 | 2.3 | 1.8 | 1.5 | 1.2 | 1.0 | | 85x60x4 | 94.01 | 22.12 | 6.4 | 4.5 | 3.3 | 2.5 | 2.0 | 1.6 | 1.3 | 1.1 | | 85x60x5 | 113.7 | 26.75 | 7.8 | 5.4 | 4.0 | 3.0 | 2.4 | 1.9 | 1.6 | 1.4 | | 95x60x5 | 147.21 | 30.99 | 10.1 | 7.0 | 5.1 | 3.9 | 3.1 | 2.5 | 2.1 | 1.7 | | 105x60x5 | 185.85 | 35.4 | 12.7 | 8.8 | 6.5 | 5.0 | 3.9 | 3.2 | 2.6 | 2.2 | | 115x60x5 | 229.86 | 39.98 | 15.7 | 10.9 | 8.0 | 6.1 | 4.8 | 3.9 | 3.2 | 2.7 | | 115x60x6 | 268.71 | 46.73 | 16.7 | 12.7 | 9.4 | 7.2 | 5.7 | 4.6 | 3.8 | 3.2 | | 115x65x8 | 362.92 | 63.12 | 16.7 | 17.2 | 12.6 | 9.7 | 7.7 | 6.2 | 5.1 | 4.3 |
C Type Parapet Posts:Parapet and spandrel posts are designed as fixed base cantilevers.
