Abstract
Wind turbine blade comprising two or more blade sections each of which defines a non-joint zone and, at one or each of its ends, a joint zone. The blade sections are connected in pairs such that the joint zones of each pair are connected at a joint, whereby the joint is positioned between two non-joint zones. At least one of the joints have an increased thickness and a wider chord relative to the thickness and the chord of the two non-joint zone between which the joint is positioned so as to increase the second moment of inertia in the area of the joint.
