Inverted Square T-beam

Definition

Defining inequalities

abs(x)<=t/2 and d - h<=y<=d or abs(x)<=b/2 and 0<=y<=d - h

Alternate name

Lamina properties

(b/2, 0) | (b/2, d - h) | (t/2, d - h) | (t/2, d) | (-t/2, d) | (-t/2, d - h) | (-b/2, d - h) | (-b/2, 0)

0<t<b and 0<h<d

(data not available)

A = b (d - h) + h t

x^_ = (0, (b (d - h)^2 + (2 d - h) h t)/(2 (b (d - h) + h t)))

Mechanical properties

J_x invisible comma x = 1/3 (b (d - h)^3 + h t (3 d^2 - 3 d h + h^2))

J_y invisible comma y = 1/12 (b^3 (d - h) + h t^3)

J_zz = 1/12 (b^3 (d - h) + 4 b (d - h)^3 + 4 h t (3 d^2 - 3 d h + h^2) + h t^3)

J_x invisible comma y = 0

Distance properties

d - h | (b - t)/2 | h | t | h | (b - t)/2 | d - h | b

p = 2 (b + d)
