Component-based finite element design of steel connections
This publication introduces the Component-based Finite Element Method (CBFEM), which is a novel approach in the structural design of steel connections and joints. It allows engineers to analyze and assess generally loaded joints and connections with varying complexity of geometry.
CBFEM is a synergy of the standard approach to connection design (component method) and finite elements. Implementation of the CBFEM for the structural steel design represents a qualitative leap for the whole structural engineering industry.
Following the CBFEM principles, this publication presents benchmark cases for its validation and verification for various structural steel joints and connections. The hierarchy of the system response quantity is prepared for welded and bolted connections as well as for column bases. Each benchmark case shows results from the analytical model according to design standards followed by references to laboratory experiments, validated models, and numerical experiments.
Results from CBFEM calculations are thoroughly analyzed, taking into account the global behavior of the joint and verification of resistance.
