    • 3.1 Moment d’In\u00e8rcia \u201cI\u201d (mm4)<\/strong><\/li>\n<\/ul>\n

      \u00c9s la propietat geom\u00e8trica de la secci\u00f3 transversal del panell que quantifica com es distribueix la seva massa respecte del centre de gravetat. Aquest valor \u00e9s determinant per calcular la resist\u00e8ncia a la flexi\u00f3: com m\u00e9s moment d’in\u00e8rcia, menor ser\u00e0 la tensi\u00f3 interna i la fletxa (curvatura) que patir\u00e0 el panell davant d’una c\u00e0rrega de vent determinada.<\/p>\n<\/td>\n<\/tr>\n

    • 3.2 M\u00f2dul el\u00e0stic \u201cE\u201d (N\/mm2)<\/strong><\/li>\n<\/ul>\n

      Tamb\u00e9 conegut com a M\u00f2dul de Young. \u00c9s una constant intr\u00ednseca dels materials que defineix la relaci\u00f3 entre la for\u00e7a aplicada i la deformaci\u00f3 resultant a la zona el\u00e0stica. Un panell amb un m\u00f2dul d’elasticitat elevat patir\u00e0 menys deformaci\u00f3 o despla\u00e7ament davant de la mateixa c\u00e0rrega, garantint una plane\u00eftat m\u00e9s gran a la fa\u00e7ana.<\/p>\n<\/td>\n<\/tr>\n

    • 3.3 Rigidesa \u201cEI\u201d (kNcm2)<\/strong><\/li>\n<\/ul>\n

      \u00c9s el resultat de multiplicar el moment d’in\u00e8rcia (I) pel m\u00f2dul el\u00e0stic (E). Aquesta \u00e9s la dada t\u00e8cnica m\u00e9s pr\u00e0ctica per al c\u00e0lcul d’estructures, ja que combina la geometria del panell amb la qualitat dels seus materials. Per a una configuraci\u00f3 de suports fixa, la rigidesa \u00e9s l\u00fanic valor necessari per predir la fletxa m\u00e0xima admissible.<\/p>\n<\/td>\n<\/tr>\n

    • 3.4 L\u00edmit el\u00e0stic \u201cR p0,2″ (N\/mm2)<\/strong><\/li>\n<\/ul>\n

      Representa la tensi\u00f3 m\u00e0xima que el panell pot suportar comportant-se com a material el\u00e0stic. Fins aquest punt, si es retira la c\u00e0rrega, el panell recupera la forma original gaireb\u00e9 al complet (99,8%). Un l\u00edmit el\u00e0stic alt assegura que la fa\u00e7ana no patir\u00e0 abonyegaments o deformacions permanents despr\u00e9s d’esdeveniments clim\u00e0tics severs.<\/p>\n<\/td>\n<\/tr>\n

    • 3.5 C\u00e0rrega de trencament (l\u00edmit \u00faltim) \u201cRm\u201d (N\/mm2)<\/strong><\/li>\n<\/ul>\n

      \u00c9s la tensi\u00f3 m\u00e0xima que el material pot resistir abans de trencar-se f\u00edsicament. Si se supera el l\u00edmit el\u00e0stic, el material entra en una fase pl\u00e0stica irreversible; si la tensi\u00f3 continua augmentant fins a assolir aquest valor Rm, es produeix la fallada estructural i el trencament del panell.<\/p>\n<\/td>\n<\/tr>\n

    • 3.6 Allargament al trencament \u201cA\u201d (%)<\/strong><\/li>\n<\/ul>\n

      Aquest par\u00e0metre mesura la ductilitat del material, \u00e9s a dir, quant es pot estirar el panell des que supera el l\u00edmit el\u00e0stic fins que finalment es trenca. Un percentatge m\u00e9s alt indica que el material \u00e9s capa\u00e7 d’absorbir energia deformant-se abans de fracturar-se, una caracter\u00edstica de seguretat important.<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
