The pneumatic structural element comprises from one to a number of interconnected elements of the following construction: two hollow bodies made of textile material coated in a gas-type manner and each having two end caps are assembled such that they produce a common sectional area. The edging of this sectional area is formed by two curved tension/compression elements into which is clamped a gas-tight web made of a flexible material of high tensile strength. This web can be connected to the tension/compression elements in a gas-tight manner. By filling the two hollow bodies with compressed gas, a tensile stress σ pretensions said web. This pretensioning increases the bending rigidity of the tension/compression elements. If a plurality of such elements are combined to form a roof, every two adjacent hollow bodies thus form a sectional area with a tension/compression element and web.
