Abstract |
Increasingly bigger self-propelled cranes are being constructed, and their component parts are tending to be increasingly lighter; thus the risk of sudden buckling due to elastic instability is becoming more prevalent. In the light of the standard procedure adopted in Italy for calculating lattice jibs, the authors examine the critical axial load with reference to the energy criteria and the behaviour of structures exposed to the risk of buckling. An example of the actual calculations involved in the design of a jib of this type is appended. |
