influence line diagram

Influence line for redundant structures can be obtained by

• castiglianos's theorm

• Muller Breslau principle

• unit load theorm

• Maxwell-Betti reciprocal theorm

Muller Breslau Principle in structural analysis is used for

• drawing ILD for any force function

• writing virtual work equation

• Superposition load effects

• none

For drawing ILD, what value of test load is assumed?

• 1 unit

• arbitrary

• depends upon structure

• 0

in influence line diagrams (ILD) :

• Points remain fixed, position of load changes

• Points change, position of loads remain fixed

• Both of them changes

• Neither of them changes

ILD of statically determinate beams consists of curve as well as straight lines.

State whether the above statement is true or false.

• true

• false

If we require to construct ILD of vertical support at a pin joint, then according to Muller-Breslau principle, by which type of support should it be replaced?

• Roller guide

• Pin roller

• Fixed support

• Hinge

Muller Breslau principal for influence line is applicable for :

• simple beam

• continuous beam

• redundant beam

• all of these

Concept of ILD is only applicable to the static indeterminate structure.

• True

• False

ILD is drawn according to which principle

• Muller Breslau principle

• Eddy's theorem

• Eulers theorem

• Mohr's theorem

Muller Breslau principle can be used to

• Determine the shape of influence line

• Indicate the parts of the structure to be loaded to obtain the maximum effect

• Calculate the ordinates of the influence line

• All correct
