2003-2006 An original structural concept of footbridge, Taylor-made for fibre reinforced polymer (FRP) is proposed in this work. The main structural element of the footbridge here described is a selfstressed arch. The arch consists of an elastically bent pultruded tube whose geometry is an elastica, a cable anchored [...]
2014 Structures made from re-used manufactured goods are shown in this paper. The different parameters involved in the recycling scheme are enumerated and three specific types of structures are studied. First, the re-use of bicycle wheels to generate a truss structure is discussed. Second, sandwich panels made of re-used drinks cansfor [...]
When looking a catapult that is ready to throw a stone, one can observe that there is very little displacement of the beam when the stone is put on the catapult. This is due the fact that the rope act as a column and takes the load of the stone. The rope has been prestressed by the bending energy stored in the wooden beam. By adding weight on the catapult the rope will lose tension. The same concept can be used to shorter the span of a beam or a bridge.
