Materia : Correa CT-08 Fecha : Mayo. 2004Diseño : C.J.V.
1.- IntroducciónEn la presente memoria de Cálculo se procederá a realizar el diseño de las fundaciones para la correa CT-08para el Proyecto "Correas - Coemin".
2.- Báses de Cálculo2.1.- Materiales
Hormigón Estructural H25, factor de confianza 90% y f'c = 200 kg/cm2Acero para hormigón A63-42H, con fy = 4200 kg/cm2
2.2.- SolicitacionesCargas Muertas (CM)Sobrecargas (SC)Viento (V)Sismo (S)Tensiones de Operación (CT)Impacto (I)
2.3.- Combinaciones
En estructuras metálicas las combinaciones de carga a usar serán las siguientes :
: CM + SC + I + CT
- Caso II :a) CM + (SC)b + I + (V o S)c
b) CM + SC + 0.5 V
- Caso III : CM + (SC)b + I + (V o S)c
- Caso IV : 0.9 CM + I+ (V o S)c
- Caso V : 0.9 CM + (V o S)c
b. Sobrecarga Reducida (SCR) se usará en la combinación con la carga sísmica.
c. Se usa V o S, eligiendo la carga más desfavorable.
El factor de mayoración (FM) que se aplicará a las tensiones admisibles será:
Caso I : FM= 1,00Caso II a V : FM= 1,33
Las estructuras se analizarán para 2 direcciones horizontales mutuamente ortogonales y sus miembros se diseñarán para la combinación más desfavorable.
2.4.- Normas de Diseño
