Traditionally, earthquake-resistant design has been strength-based, using linear elastic analysis. Since inelastic behavior is usually allowed for strong earthquakes, this is not entirely rational. Strength-based design considers inelastic behavior only implicitly. Displacement-based (or deformation-based) design considers inelastic behavior explicitly, using nonlinear inelastic analysis. Displacement-based design recognizes that in a strong earthquake, inelastic deformation (or ductility) can be more important than strength. PERFORM-3D allows you to use displacement-based design.
Procedures for displacement-based design using inelastic analysis are specified in ASCE 41, “Seismic Rehabilitation of Existing Buildings”. ASCE 41 applies to the retrofit of existing buildings, but the procedures can be applied to the design of new buildings. PERFORM-3D implements the procedures in ASCE 41. However, PERFORM-3D is a general tool for implementing displacement-based design. It is not limited to ASCE 41.

Written in easy to understand language, this self-explanatory guide introduces the fundamentals of finite element methods and its application to differential equations. Beginning with a brief introduction to Sobolev spaces and elliptic scalar problems, the text progresses through an explanation of finite element spaces and estimates for the interpolation error. The concepts of finite element methods for parabolic scalar parabolic problems, object-oriented finite element algorithms, efficient implementation techniques, and high dimensional parabolic problems are presented in different chapters. Recent advances in finite element methods, including non-conforming finite elements for boundary value problems of higher order and approaches for solving differential equations in high dimensional domains are explained for the benefit of the reader. Numerous solved examples and mathematical theorems are interspersed throughout the text for enhanced learning.

The CBFEM (component-based finite element model) is a new method to analyze and design connections of steel structures. The design focused CM (component model) is compared to FEM (finite elements models). The publication introduces Benchmark Cases for Validation and Verification procedures of structural steel joints. The hierarchy of the System response quantity is prepared for welded and bolted connections as well as for column bases. Each Benchmark Case starts with the task description and includes results of prediction by the analytical model according to EN 1993-1-5, references to experiments, validated the model and numerical experiments, results of prediction by design Finite Element Analyses described in terms of global behaviour and verification of resistance. At the end of the publication, the reader may check his calculation on Benchmark cases prepared for the particular joint. Finite Element Analyses is a current step in the design of steel connections, which allows predicting the generally loaded joints with a complex geometry with the same efficiency and accuracy as the traditionally designed connections based on the best engineering practice. Implementation of the FEA models for the structural steel detailing creates the qualitative step as we may see in other areas of engineering.
