Basic Statements 11

Question 1

The strength with the calculation method using Fourier series of arbitrary bending moment distributions is that any bending moment distribution can be described by Fourier series.

Answer 1

True

Question 2

Effective breadth has to be considered in the calculation of the moment of inertia, Iy

Answer 2

True

Question 3

The constant, beta, which occurs in the expression of the effective breadth in the Fourier series method can be put to zero for shallow, thin, widely spaced webs.

Answer 3

True

Question 4

The Airy stress function is a product of two functions f(y) and g(x), which includes four constants that are identified by boundary conditions,

Answer 4

True

Question 5

AN unsymmetric flange does not require a separate calculation procedure in the calculation of the effective breadth.

Answer 5

False - sigma_y not= 0. Hence the stiffness must be taken into consideration

Question 6

Fourier series are described by harmonic functions which by superposition can be used to describe any load distribution or load signal time.

Answer 6

True

Question 7

For an unsymmetric flange, the stiffness of the web in the flange plate affects the displacement of the effective flange under consideration.

Answer 7

True

Question 8

Elementary cases from engineering beam theory and plate theory cannot be used in the analysis of unsymmetric flanges.

Answer 8

False

Question 9

An analogy to the calculation of the total displacement of an unsymmetric flange is the calculation of total spring stiffness for a system parallel-coupled springs

Answer 9

False - Series-coupled springs
