The timber carport, whether attached to the house or free standing is a relatively simple structure similar to a covered pergola. That is, a carport is supported by posts, poles or piers/columns, the cover is supported in turn by beams, rafters and perhaps roofing battens and the whole MUST be fixed together to resist wind forces expected in the area. Wind forces will tend to push the structure sideways (lateral forces) and to lift up the roof and attached members (uplift forces). For the first named bracing must be built into the design. For uplift forces, all fasteners (bolts, nails, nail plates, stirrups etc) must together provided strong attachments from the roofing materials itself down to the foundations.
