STUDY ON THEORETICAL ANALYSIS AND EVALUATION FOR WIND RESISTIBILITY OF THIN METAL ROOF CONSTRUCTION : Verification and development of approximate analytical solution on wind resitibility for standing seam roof construction

Abstract

An approximate analytical solution on wind resistance performance forst anding seam roof construction, which is made of 0.6mm thick fluorine contained resin plate, is developed by using the method of applying a catenary on the curved line representing floating up height of roof construction due to wind pressure. From comparison between the test result of wind resistance and that of finite element method for verification on the above solution, it is confirmed that the solution can provide estimated values on the displacement of roofing materials due to wind pressure with high accuracy. The value from the solution sufficiently coincides with the value tested particularly within the range of wind pressure from 2,000N/m^2 to 5,000N/m^2. Therefore, it has been confirmed that this method is effective for the analytical solution for wind resistance of standing seam roof of 0.6mm thick fluorine contained resin plate.
