The invention relates to a method for producing structural elements (14) that comprise a hollow profile (1) made of continuous fibre-reinforced plastics material that comprises a thermosetting matrix material that has a softening temperature that is below the cross-linking temperature, and at least one load-application element (15), and to a structural element (14) produced by the method and comprising a hollow profile (1) made of continuous fibre-reinforced plastics material that comprises a thermosetting matrix material that has a softening temperature that is below the cross-linking temperature, and at least one load-application element (15), the hollow profile (1) and the load-application element (15) being interconnected in a form-fitting manner. The method according to the invention comprises at least the following method steps: a. providing a cut-to-size hollow profile (1) made of plastics material (3) that is reinforced by continuous fibres, on a liner (2), wherein the liner (2) forms the inner lateral surface of the hollow profile (1), and wherein the hollow profile (1) is impregnated by means of heating to a temperature that is equal to or above the softening temperature of the matrix material (9) and below the cross-linking temperature of the matrix material (9); b. removing the liner (2) in the inner region (17) of the hollow profile (1) that is intended for load application; c. arranging a load-application element (15) on the inner region (17) of the hollow profile (1) that is intended for load application; d. consolidating and functionalising the structural element (14) consisting of the hollow profile (1) and the load-application element (15) by means of heating the structural element (14) to a temperature that is equal to or above the cross-linking temperature of the matrix material (9) and applying a radially inwardly acting pressure to the structural element (14), wherein the hollow profile (1) is moulded onto the load-application element (15) in a form-fitting manner.
