Plastic Analysis of Grillage under a Point Load

초록

Grillage is common types of structures in marine and land based structural system. The plastic collapse modes of those structures are dependent on the loads, which are lateral, in plane or combination of those directions as well as boundaries. In this paper, a plastic analysis method is appled to grillages or grids under a single concentrated load to find the worst load point. The worst load point would be either at the central interaction or on the point of between intersections. In the present paper, general formulae for plastic collapse for the square grillages with simply-supported boundaries are derived.
