  • 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....

  • Revision questions coming up soon.

    To help those  students who are  resisting  Structures 1A and Structures 2 in August/Sept I will be  uploading a question for each  course on a regular basis .

  • Question 16

    This week its something  a bit different! Understanding the causes of deterioration is just  as  important as  resolving  vectors. The rail bridge over Westmoreland Road, (on the route of the U18 bus leaving  Oldfield Park  on the way to uni) Bath,...

  • 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 12

    For height  H of ? and L= ?m  the  correct answer is  16.7kN,  well done to  all  those who got the right  answer.  Hopefully  you  took  moments about the support  pins to find the vertical  reactions,  then  if you  take...

  • Question 11

    This weeks question is submitted by our very own Tom Reynolds a PhD students studying the dynamic performance of Timber connections who has a healthy interest in slack-lines. The violin player hears a  tearing  sound  and  quickly  sees that  the cable at...

  • Christmas and New year holiday

    Happy new year to everyone.  The weekly blog questions will start again ready for Semester 2.  In the mean time I hope you are all outside enjoying the snow. Why not try to build an ice sculpture. For more inspiring...

  • Question 10: Buro Happold & Emirates Air Line

    Those kind folks at Buro Happold have written a difficult question for all us structural engineers to think about for the next 2 weeks. As its a bit harder than usual we have doubled the prize money, a £20 Amazon Voucher could...
