4 - Loading Your Model

b - Standing Upright

• On each floor, place the mass you calculated for the vertical load test.
  
  
• You can apply a sideways load to each floor of your model by using mass to pull strings attached to the model.
  
  
• You can get the right force into the string by hanging it over a pulley or round bar and suspending mass from the other end.

• The lengths of strings attached to the model must be horizontal.
  
  
• For each floor, the mass on the end of the string will be the one you calculated for the Earthquake Load Test.
  (see Earthquake Load Test Page 3 - Finding the Mass)
  
  
• Make sure that you spread the load on each floor of your model. We used 2 strips of MDF glued together to spread the load along one edge of each floor and another pair on the opposite side to stop the string cutting into the model.

Warning ! If you attach a string to one point on your model, when the string is pulled, it could break the model at that point.
