This paper presents the construction process, full scale tests and numerical model of a long barrel-vaulted gridshell prototype made of Eucalyptus globulus Labill. The species potential for gridshell structures is analyzed. A novel erection method taking advantage of the deployable capacity of the grid during curving process is described and implemented in the construction of the full scale prototype. Also the results of local bending tests with large deformations of the laths, shear tests of the joints and bending tests of composite beams with semi-rigid connections are shown. The latter are compared and discussed with those obtained from different proposals of 2D numerical models which include eccentricities of the joints and semi-rigid behavior by the use of spring elements with linear and nonlinear laws. Finally, the results of two load tests performed to the full-scale prototype and monitored by photogrammetry technique are presented. The results are also compared with linear and non-linear 3D numerical models. The models considering non-linear behavior of the connections showed good agreement over the whole load range tested. | |
