Dear Sir,

We want to knom if we can use flexible floor in our modle.For example we use cotton string to take the place of stip of MDF as beams .And if it will influence

Hi judge,
I am from Team 2- Blazers of Chongqing university. When we design our building model, we have encountered some problems. So we hope you can give us some advices.
1. Should we make fixings for steel blocks on each floor? Do the fixings have to glue on our model? And will the top floor carry the steel blocks?
2. We find the model is oversimplified, and it can hardly be representative of our real building. So we are wandering that how could we establish the connection between our model and real building?
3. Could you provide the tensile strength, compressive strength and shear strength of MDF strip to us?
4. Could you provide mechanical properties of paper? Which kind of paper will we use in our model?
5. In the "specification of model building", there is a rule that "So for each storey of your
model, half the length of the outside perimeter must be left completely clear of any materials
between the top of one floor and the bottom of the floor above." So it means if the perimeter of our model is 15*4=60cm, we have to left at least 30cm clear. Nothing can be used between the top of one floor and the bottom of the floor above?
Thank you very much for your guidance. |

Hi Jiang Wei
Answers to your questions are:
1.Yes you need fixings on each floor and they should be glued together and to the floor. Your steel blocks will also be fitted and glued in place after the model is fixed to the shakking table ready for testing. Read the specifaction carefully about floors and loading.
2. Please read section 1 of the Specification for the Model Building. We are not looking for an exact representation but your model must be the same shape as the real building with similar bracing arrangements.
3. We can't. I suggest you find this information on the internet or test some MDF strips yourself and take the strengths from that.
4. Again we can't. The type of paper to be used will have a weight of approximately 100 gsm. I suggest you test some paper too.
5. I think I understand you and you are correct. For examples of how this rule works see http://www.ideers.bris.ac.uk/comp/rule5_explain.html |
