| Abstract |
In this paper, first of all, access to the relevant literature, discusses the tensioned membrane structure of the wind tunnel similar rules, and from selected materials to manufacture the model, in some extent, in strict accordance with the wind tunnel similar rules, in order to effectively control and grasp The pre-stressed, and in accordance with the current popular form of membrane structure and the extensive application, selected and produced an umbrella tension membrane structure vibration model of the wind. Does not change its form, under the conditions , around the model ,respectively Evenly imposed on two pretension, using the BLWT (Eiffel type) wind tunnel of CBNU Division of Architectural and Urban Engineering for their flexibility wind vibration responsion test. Observation of the existence of significant differences in pretension circumstances, the wind speed at different umbrella membrane structure under the conditions of X-axis, Y-axis wind vibration response, through drawing contour lines, analysis tensioned membrane structure by the wind vibration changes of each location to explore the comparison in different pretension, different wind speeds, the membrane structure of the wind vibration response (displacement) response. For the future to engage in field measurements and numerical wind tunnel simulation analyse of similar form model, provide an effective basis experimental evidence is far-reaching significance. |
