Hi, I am trying to help my friend design a timber roof purlin for a residential house. The roof is pitched at 35 degrees and I have to account for snow load, wind load etc.
I would really appreciate if anyone has any examples of timber purlin design in accordance to Eurocodes or British...
How can i estimate the impact force generated by an object, for example a object with mass of 2kg falling from a height of 1m on a fixed end beam. Will it be possible to work out the impact force generated without requiring any experimental observations and without knowing the time interval over...
If a central concentrated load is applied mid span of a fixed end beam, then the maximum bending moment occurs at the centre and at the ends of the beam. If at these points moment is greater than the plastic moment, plastic hinges will form. Where will be the maximum stress? Will it be at the...
I'm conducting an experiment by which I am dropping a weight (1kg) from different heights (0.1m – 1.5m) on a model scaffold structure. How can I differentiate when the load is dynamic and when it becomes an impact load, and how can I establish a transition between the two?
This question arose...
I'm conducting a study into the effect of impact loads on sidewalk shed as it is known in USA, pedestrian walkway in England, to protect the public from falling objects/debris.
I would like to ask if any one knows whether there is any relevant design manuals out there that can help and how i can...
Hi, I would appreciate if anyone can clarify what is meant by strain rate effect of timber/steel, and if/how the strain rate of these materials can be altered. Many thanks
