Trees are characterized by interesting structural features which result in an efficient dynamic behavior. As a result, trees with high slenderness ratios are able to survive strong wind events. A likely explanation is that the hierarchical branching architecture prevents trees from excessive vibration. Inspired by the excellent performance of trees under dynamical loads, this study explores the feasibility of mimicking the fractal branching architecture of trees to design novel civil engineering structures. This study will analyze the self-similar dynamic properties of such bio-inspired tree-like structures. Experimental studies will be conducted to validate the analysis.
1. Design, analyze and build a small-scaled bio-mimicked tree-like structure.
2. Perform experiments to access the performance of tree-like structure under dynamic loads.
Through this project the students will be able to
(1) explain why trees are efficient in resisting wind loading
(2) analyze complex structural models
(3) characterize advanced structural dynamic behavior
