The locking mechanism system of roofing sheets is fulfilled by designing of crest profile where the upper side is wider than below. The matrix of FRP composite is unsaturated polyester resin and the reinforcement is E-glass. Reinforcement type is chopped strand mat where the chopped mats orientation is in random so that the material elastic properties type is assumed as planar (2D) isotropic. The new profile of FRP roofing sheets is designed for industrial or warehouse building standard with dimensions 2 mm thickness, 406 mm effective width, and 11.4 m length. It is supported by seven internal spans, two end spans, and two overhang spans. The length of internal spans and end spans are 1.2 m and overhang spans are 0.3 m. It is modeled on Catia V5 finite element program and subjected by inward rectangular wind force based on ASTM D3161: 60 mph, 90 mph, and 110 mph. Simplification in finite element model is made by using elastic modulus as isotropic material. Linear tetrahedron element was choosen for finite element model which is consists of 250,612 nodes and 759,416 elements. The maximum values of both von Mises stress and translational displacement were found at the two end spans of roof structure. They were 4.29 MPa and 0.991 mm (for 60 mph wind speed), 9.14 MPa and 2.12 mm (for 90 mph wind speed), and 13.5 MPa and 3.14 mm (for 110 mph wind speed). Based on maximum stress criterion and maximum deflection for static strucuture, the model is safe. Opini Anda Klik untuk menuliskan opini Anda tentang koleksi ini!
