A fast estimating model for deformation of metal roof sheathing with wind pressure load

Standing seam metal roof systems are widely used in many large buildings such as airport terminals, sports stadiums and theatres. However there are many problems such as deformation and wind-lift that caused by big wind or heavy rain. To monitor these damages and take maintenance measures in advance are very important to avoid economic losses and personal injuries. Considering the area of roof system is large and detection sensor cannot obtain the overall deformation of the metal board, this paper is trying to build a model by which we can obtain the overall deformation in case of only knowing the deformation of some points. This model uses an improved way of superposition method based on Levy-type solution which can estimate the overall deflection in real-time. Through comparison with simulation results of the finite element software we conclude this model is relatively accurate and can be used as assisted reference in monitoring damage and health management of metal roofing system.
