Apndice B. Revisin a flexocompresin en los extremos.

En la revisin a flexocompresin se considera una seccin compuesta por los dos perfiles OR 89x6.3 y los dos espesores de las alas soldadas al OR, por lo tanto en la siguiente figura se muestra la consideracin de la seccin transversal analizada.

Figura 1. Seccin para las secciones de los extremos.De la figura 1 se tienen las siguientes propiedades de la seccin compuesta.Tabla 1. Propiedades 2OR+PL

A=77.28cm2

J=2178cm4

I33=2243cm4

I22=1353cm4

I23=0cm4

S33=252cm3

S22248cm3

Z33=343cm3

Z22=305cm3

r33=5.38cm

r22=4.18cm

Se considera una revisin para una seccin tipo 1, por lo tanto se utilizara la siguiente ecuacin de las NTCM 2004.

La resistencia Py es:

El momento plstico Mpx es:

El momento plstico Mpy es:

Conforme a los ejes de la figura 1 el eje 3 ser el eje x y el eje 2 ser el eje y, por lo tanto se realiza la siguiente evaluacin en los puntos extremo del tanque de flotacin que estn cercanos del apoyo como se muestra en la figura 2.
