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

NCh 432 " Cálculo de la acción del viento sobre las construcciones "NCh 433 " Diseño sísmico de edificios "NCh 2369-2003 " Diseño sísmico de estructuras e instalaciones industriales "ACI 318

3.- Diseño Fundaciones

Para el diseño de las fundaciones se utilizará el modelo estructural de la correa, adicionandolé las fundaciones, con lo cual losvalores a utilizar serán obtenidos directamente del programa.
