• ### 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  drop-in 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), Super-imposed 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. Pre-stressing a simply supported beam For the simply supported pre-stressed 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...
