1.- ANTECEDENTES: se requiere la revisión estructural de un tanque cilíndrico vertical de 10.5 m de diámetro y 4.0 m de altura con una capacidad de almacenamiento de 300 m3 de agua, conformado en placa lisa de acero inoxidable, se encuentra apoyado sobre una cimentación en concreto reforzado al exterior de la planta de proceso. 2.- REGLAMENTOS DE DISEÑO UTILIZADOS: API-650 Welded steel tanks for oil storage_1993. Manual de Diseño de Obras Civiles de la C.F.E. 3.- BIBLIOGRAFIA UTILIZADA: “Stresses in Plates and Shells”,A.C. Ugural,Mc Graw-Hill.1981 “Guide to storage tanks & equipment”.B.Long, B.Garner, professional Engineering Publishing.2001 “Aboveground storage tanks”, P.E. Myers, Mc Graw-Hill.1997 4.- ANALISIS DE CARGAS: 4.a.- Antecedentes: dada la estructura en cuestión, su tipo, geometría, y al encontrase ubicada al exterior de la planta, en base al reglamento se hará una revisión para cargas gravitacionales de operación y cargas sísmicas las cuales rigen el diseño. 4.b.- Materiales para análisis: para la elaboración del modelo estructural se han considerado básicamente los siguientes materiales: acero. Los valores de las propiedades mecánicas para este material se muestran a continuación: Acero Módulo de Elasticidad: 2’089,704 kg/cm² Cociente de Poisson: 0.3 Densidad: 7,833 kg/m³ Amortiguamiento Crítico: 0.03 Coeficiente Térmico (α): 6.6 x 10-6

4.c.- Cargas de Análisis: las cargas a considerar son: Carga Muerta – CM, constituída por: Peso propio del tanque que se toma en cuenta con el comando “selfweight” de la plataforma de análisis. Cargas Hidrostática – CH: Carga trapecial sobre las paredes del tanque considerando un peso volumétrico del agua de 1.0 ton/m3. Carga uniforma sobre el fondo del tanque, 3.5 ton/m2 considerando un peso volumétrico del agua de 1.0 ton/m3. Carga sísmica – CS: Para las cargas accidentales por sismo (CS) se toman los valores de un espectro de diseño para la zona sísmica “B” y un tipo de suelo II, se tienen entonces los siguientes valores para una revisión estática simplificada: coeficiente sísmico básico, c = 0.30 factor de ductilidad, Q = Q’ = 2.0 coeficiente sísmico, Cs = 0.15 Dichas cargas se integran en el modelo como cargas uniformemente distribuidas y cargas puntuales sobre los elementos estructurales. 4d.- Combinaciones de Cargas: el caso de carga básico que se considera es entonces el siguiente: 4d.1.- Carga muerta – CM. 4d.2.- Carga hidrostática - CH. 4d.3- Carga sísmica - CS. A partir de tales casos de carga básicos se genera la siguiente combinación de carga: 4d.4.- 1.0 CM + 1.0 CH + 1.0 CS

4e.- Formulación del modelo estructural: los elementos de la estructura se han modelado mediante elementos lineales y 2D existentes en la librería de la plataforma de análisis, las conexiones entre ellos se han supuesto como nudos rígidos . Mediante la plataforma de análisis se lleva a cabo un análisis de tipo estático lineal, obteniéndose así los valores de las reacciones de apoyo, solicitaciones en los elementos, desplazamientos y rotaciones para los distintos casos y combinaciones de carga. 5.- DISEÑO ESTRUCTURAL: 5a.- Diseño de la estructura: al emplearse la plataforma de análisis para los elementos 2D y lineales de acero se encontraron sus deflexiones, esfuerzos cortantes SX, SY y SXY, esfuerzo máximo de Von Mises, esfuerzo máximo de Tresca; para revisar la seguridad estructural se utiliza la teoría del esfuerzo cortante máximo para materiales dúctiles, la cual es sencilla y conservadora, que consiste en comparar el valor de dichos esfuerzos y su diferencia algebraica con el esfuerzo cortante permisible, Ssa, que es igual a 0.4 fy. Se tomaron en cuenta los siguientes valores del esfuerzo de cedencia (0.2%) para los perfiles de las secciones: acero inox. T-304 con un fy = 2140 kg/cm2. 6.- CONCLUSIONES: a partir de los resultados del análisis para los elementos placa y elementos lineales que conforman la estructura, se tiene los siguiente: 1.- Respecto a los esfuerzos cortantes máximos: El valor de los esfuerzos máximos de Von Mises se sitúa en 402 kg/cm2 sobre la parte inferior de la pared opuesta a la dirección del sismo. El valor de los esfuerzos máximos de Tresca se sitúa en 422 kg/cm2 también sobre la parte inferior de la pared opuesta a la dirección del sismo. Ambos valores son inferiores al permisible de 856 kg/cm2.

2.- Respecto a los desplazamientos: Sobre el borde superior de las paredes del tanque se presenta un desplazamiento horizontal máximo de 5.5 mm el cual es inferior al permisible de 11.4 mm considerando una deflexión de L/350 para una altura de 4.0 m de las paredes. 5.- Respecto a la presión máxima de base: Se obtuvo un valor de 8.256 ton/m2 la cual es inferior a la permisible de 12.0 ton/m2 considerando un relleno de material inerte bajo el fondo del tanque. 6.- Respecto a los atiezadores perimetrales: Se obtuvo un valor máximo de 0.683 para la demanda de resistencia de los elementos anulares. Los resultados anteriores para la estructura analisada se muestran en el Anexo #1 (imágenes del modelo), Anexo #2 (Diseño de atiezadores perimetrales) y se adjunta el Anexo #3 como archivo tipo .txt que contiene el listado de valores para los diferentes contornos de esfuerzo obtenidos en el análisis.

Cimentación para tanque ac. Inox. 300m3 cap.

Se emite el presente addendum que cubre el diseño estructural

de la cimentación para un tanque de ac. inox. de 300 m3 de

cap. y de 10.5 m de diám por 4.0 m de altura; la cimentación

es tipo anillo conformado en concreto reforzado y se

desplantará sobre un estrato de terreno resistente.

para lo cual se han empleado los siguientes reglamentos:

Reglamento del A.C.I. 318-05.

Manual de Diseño de Obras Civiles de la C.F.E.

API-650 Welded steel tanks for oil storage_1993.

y ls bibliografía siguiente:

“Foundation análisis and design”_5ed, J.E. Bowles, Mc Graw

Hill, 1996.

“Principles of foundation engineering”_7ed, B.M. Das, Cengage

Learning, 2012.

Se lleva a cabo una revisión para cargas gravitacionales y

sísmicas, considerando los resultados arrojados por el

análisis estructural del tanque.

De acuerdo a la información de mecánica de suelos

proporcionada por el cliente, el anillo de cimentación se

desplantará sobre una plantilla de concreto f’c = 100 kg/cm2,

sobre un estrato de terreno Tipo II, el cual posee una

capacidad de carga admisible de 8.0 ton/m2 para cargas

gravitacionales y de 10.0 ton/m2 con cargas accidentales.
