Abstract
The tree has the abilities of both the self-optimization and the self-restoration by changing to adapt each part of stem and root, opposing power to receive from nature. Present study investigates structural morphology and suspension mechanism of root and stem to zelkova and Pinus Thunbergii applied gravity and wind load to stem using two dimensional large deformation finite element analyses. It revealed that both zelkova and Pinus Thunbergii well utilize physical properties of soil and increase the holding power of soil by spreading their roots for appropriate direction.
