Analytical method of structural behaviours of a hybrid structure consisting of cables and rigid structures

An analytical method of structural behaviors of a hybrid structure which consists of cables and rigid structures is proposed and the following items are studied. (1) Introduction of the kinematic equation and the equilibrium equation, (2) Classification of stable and unstable hybrid structures. (3) Estimation of pre-stress modes and the introduction of pre-stress. (4) Stability under the introduction of pre-stress, (5) analytical method of stress and displacement under static loads, and (6) vibration analysis. In order to examine the validity of the proposed analytical method, the experiment on a hybrid structure model is reported, taking into consideration the introduction of pre-stress and the deformation under the static load.
