Question

determine the moment of inertia of the area of T- section as shown in figure fig. 6.18 below with respect to the centroid o
x- axis​

Answer 1

T Section Formula:

T SECTION BEAM

Area moment of inertia Ixx Ixx = bH(ycog-H/2)2 + bH3/12 + hB(H + h/2 - ycog)2 + h3B/12

Area moment of inertia Iyy Iyy = b3H/12 + B3h/12

Minimum section modulus Sxx Sxx = Ixx/yc

Section modulus Syy Syy = Iyy/xc
