Beams

Question 22
The beam below carries a load of triangular distribution with a maximum value of 3kN/m at midspan. The beam is made of Glulam with E=16GPa and has a second moment of area Imajor =1×10^9 mm4 Determine the deflection at...

Question 20
Here is question for all of you retaking Structures 2 in September 2013 Imagine you are assessing the interesting cantilever beam arrangement shown below, you have conclude that the moment capacity of the supports is adequate but you are worried...

Question 19
Judging from last weeks performance quite a few of you have forgotten how to draw BMD. So the next few questions will focus on this issue. The question focusses on a 3 span bridge with a dropin span in the...

Question 18
Here is a question from structures 2 but i'm sure first years will get it right. Question: Which BMD is the correct for the cantilever beam shown? Solution: Lets start from the point where the load is applied. It might...

Question 17
Okay, this is definitely a simple question to start with. Question: If x= L/3 what is the vertical reaction at support A? Solution: To solve this we need to take moment about a point that we know the moment for....

Question 15
The multispan bridge shown carries three different load types, Dead load (Red), Superimposed dead load (Blue) and Live load (Yellow). The individual spans are identical in length and stiffness. Which plausible load case will produce the maximum hogging moment in...

Question 14
Something for my Bridge Engineering Students Moment at B is Diagram 3, when the load is between B and D the moment at B is always zero Moment at C is Diagram 4, when the load is at A, the...

Question 13
Something for all my Bridge Engineering students. Prestressing a simply supported beam For the simply supported prestressed beam shown above, calculate the maximum allowable length (in meters) if the maximum tensile stresses due to the unfactored dead weight are limited...

Question 6
For the structure shown below calculate the position of the roller support from the free end of the beam (C) such that the moment at the fixed end (A) is zero kNm. [Solution x=3.33m] If you didnt get it right...
