A Simple Displacement Control Technique for Pushover Analyses

This paper explains how to control in displacement any force proportional loading. Such a procedure makes it possible to derive the complete (i.e. including the possible softening branch) response curve of a structure along any radial loading path in the force space. This is exactly what is required in the so-called pushover analysis used in the seismic assessment of structures. The proposed procedure is simple in the sense that it can be easily implemented in any classical (displacement based) finite element code through a standard displacement control loading process. Furthermore, it leads to an interesting definition of the controlled degree-of-freedom, which, in the case of the pushover analysis, could substitute the classical roof displacement.
