Study of Single Layer Two-way Grid Shell with Tension Member

We have previously reported on the buckling behaviour of single layer two-way grid shells with tension members installed as diagonals of a two-way grid. A tension member’s function is to increase the in-plane rigidity of a single layer two-way grid and improve its stability behaviour. This study treats a single layer two-way grid cylindrical shell roof comprising a prefabricated wooden truss system with tension members. We focus on tension member installation and placement pattern as both diagonal members of two-way grids and out-of-plane stiffened members in a cylindrical surface. The experimental and numerical study examines the effects of tension members on the buckling behaviour of a single layer two-way grid cylindrical shell roof.
