Basic Statements 10

Question 1

Fourier series of arbitrary bending moment distribution can be use in the calculation of the effective breadth

Answer 1

True

Question 2

An analytical solution to effective breadth can be derived using Airy’s stress function

Answer 2

True

Question 3

An important step in the derivation of effective breadth is to establish the equations to normal force equilibrium, for the effective breadth with uniform normal stress and the full breadth with the true normal stress distribution

Answer 3

True

Question 4

The section modulus of a beam does not affect the effective breadth calculation

Answer 4

False - W is an important parameter

Question 5

Important!
Effective breadth calculation procedure is used to re-establish the conditions of beam theory in order to carry out calculations more easily in structural design

Answer 5

True

Question 6

Effective breadth does not have to be considered in the calculation of the moment of inertia, Iy

Answer 6

False - Iy relates to the breadth

Question 7

The effective breadth of a flange varies with the length of the beam. This is due to variation in bending moment between supports.

Answer 7

True
