Building Tips

• We advise to start with a structure made of triangles of the same shape and to use all available anchor points. 

• Whenever possible lay part of the bridge on the ground, building a support structure that holds up the bridge.

• Use anchor points on pylons as a starting point for cables. Cables are able to span a long distance and are great to sustain suspended bridge parts with weak support.

• If the bridge should be spanning a large gap, you can build a second parallel row of triangles like this:

• Another possible solution could be to build an arch bridge that is borne by the right and left banks. The advantage of the arch bridge is that the load is carried outward along the arch to the underside of the bridge, therefore it is necessary to construct strong foundations.

• If the bridge still falls down, combine the techniques above to make it stronger.  

• Try to construct symmetric structures so load will be better distributed along the bridge and weaker elements can be found more easily.

• Remember that you can find out which elements are supporting more load, and thus will probably crack, using the stress option.

Good Work!
