Developing A Desktop Platform for Evaluating Tall Building Wind-Induced Loads and Responses

Wind is the main environmental stressor dictating the design of tall buildings. That is because of the tendency of tall buildings to respond dynamically to fluctuating wind forces and undergo significant vibrations. Design codes have several limitations when it comes to the evaluation of tall building wind-induced forces and responses. For example, design codes impose a limitation on the maximum building height, consider specific shape(s) and do not account for the building surrounding configuration.Thornton Tomasetti (TT) typically calls for wind engineering study involving wind tunnel WT testing (since design codes are limited to certain shapes and heights) to be able to quantify those forces and vibrations. The challenge is that the WT process typically requires several weeks/ months to complete which can be very preventive especially in early design stages. The research team at Ryerson University will develop a desktop platform to enable TT to quantify wind-induced response of tall buildings throughout this Engage grant. Such a desktop platform includes two components (i) a simplified structural dynamic analysis code and (ii) an aerodynamic database. The platform will be validated using a wind tunnel experiment to be conducted at Ryerson U. This desktop platform will empower TT to evaluate wind-induced forces and responses of tall buildings more efficiently . This will ultimately lead to more resilient tall buildings with a minimal undesirable effect to wind-related disasters frequently driven by the climate change. The proposed research will lead to the training of 2 HQPs (1 PhD, 1 MASc) in two priority research areas of the Canadian Government (climate change and wind-related disaster mitigation).
