We present a study on the nonlinear dynamics of a tensioned bamboo roof. Quasistatic loads, such as self-weight, initial pretension, and equivalent static wind loads are considered. Step-by-step numerical time integration via Finite Differences is implemented to solve the nonlinear differential equations of motion. As large displacements are considered, and large pretension axial forces are applied, geometric nonlinearity is present in the formulation. Also, linear elastic behavior of the bamboo is implemented, based on experimental data. Future work will implement random nature of wind forces using a synthetic wind approach, and nonlinear material behavior.
