Imperfection

词汇表条目

In structural analysis, imperfection is an assumed production-related deviation of structural components. It is assumed that, for example, a support has both a curvature and an inclination and this geometric imperfection significantly influences the buckling behaviour.

Exemplary are the standards EN 1993‑1‑1, EN 1993‑1‑6 and EN 1992‑1‑1. They include the information about the type and size of imperfections, which usually must be taken into account for the stability analysis.
