Wind vibration response analysis of saddle-shape membrane structure by additional-damping method

The vibration caused by wind is a critical reason that lead to the membrane structure break, and the study of the interaction between wind and membrane structure is one of hot and difficult subjects. Recently, people generally establish programs to solve the problem by Newmark method together with Newton-Raphson. In this paper, MATRIX27 element was applied to instead of the damping which caused by wind. The spectral representation method was used to simulate the stochastic wind field, and ANSYS software was proposed to analyse the wind-membrane interaction. Thus,this paper not only avoided the heavy task of programming, but also offered a new way to adopt ANSYS to study the wind sensitive structures such as membrane.
