EXPERIMENTAL STUDY ON BUCKLING BEHAVIOR OF SINGLE LAYER TWO-WAY GRID CYLINDRICAL SHELL ROOF COMPOSED OF SMALL ROUND TIMBER WITH TENSION MEMBERS IN OUT-OF-PLANE

Abstract

This paper treats the experiment of single layer two-way grid cylindrical shell roof composed of round timber with tension members. The short diagonal tension members and the long tension members are used to stiffen the rigidity of two-way grid cylindrical shell roof. The tension member placement, the introducing initial axial force to tension members and the load patterns are considered to investigate the buckling behavior of the single layer two-way grid cylindrical shell roof. The effects of tension member placement and tension member initial axial force on the load-deformation behavior and the buckling behavior are examined to use the experimental and numerical results.
