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 the structure?
Which plausible load case will produce the maximum sagging moment in the structure?
If you are struggling with this then have a look at the Solution, it involves influence lines
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...
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...
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...
