DOUBLE-LAYER TENSEGRITY GRIDS: STATIC LOAD RESPONSE. II: EXPERIMENTAL STUDY

This is the second of a 2-part study of the response of a type of double-layer tensegrity grid (DLTG) to static load. The first part introduced the concept of double-layer tensegrity grids (DLTG). The analytical part of this study employed a flexibility-based linear model to obtain the structural respone to static load. This present study compares linear and nonlinear analytical results with experimental results of a larger model and monitors in more detail member force distribution under varying levels of prestress. It was found that the first-order analytical model underestimates the stiffness of DLTGs. The actual displacements are considerably smaller than predicted by the model. The nonlinear model predicts the load-deflection response well. Conclusions drawn from the study are discussed.
