shell constructions archit.

Помогите, пожалуйста, перевести фразу
the roof were shell constructions

Встречается в следующем контексте:
As the Romanesque style of architecture was succeeded by the Gothic, the previously almost monolithic walls were progressively replaced by filigree structures that may be regarded as precursors of the skeleton used in present-day building techniques. The roof were shell constructions with cross-support, resting on pillars and loadbearing walls.

Заранее благодарна

ср. с нем. Schalendach - покрытие в виде свода-оболочки
посмотрите в интернете свод-оболочка, купол-оболочка
