A nondestructive method for controlling wind loads and wind-induced responses of wooden pagoda

Abstract
High-rise wooden pagodas generate large displacement responses under wind action. It is necessary and wise to
reduce the wind loads and wind-induced responses on the architectural heritage using artificial plants, which do not damage
ancient architecture and increase greenery. This study calculates and analyzes the wind loads and wind-induced responses on the
Yingxian Wooden Pagoda, in China, using artificial plants via the finite element analysis (FEA). A three-dimensional windloading field was simulated using a wind tunnel test. Wind loads and wind-induced responses, including the displacement and
acceleration of the pagoda with and without artificial plants, were analyzed. In addition, three types of tree arrangements were
discussed and analyzed using the score method. The results revealed that artificial plants can effectively control wind loads and
wind-induced displacements, but the wind-induced accelerations are enlarged to some extent during the process. The height of
the tree significantly affected the shelter effects of the structure. The distance of trees from the pagoda and arrangement width of
the tree had less influence on shelter effects. This study extends the understanding of the nondestructive method based on
artificial plants, for controlling the wind base loads and structural responses of wooden pagodas and preserving architectural
heritage via FEA.
