If you ever started to do linear static FEA Analysis, you probably encountered the following singularity error: ERROR [2007]: FACTORIZATION FAILED DUE TO A SINGULARITY AT TRANSLATION-X OF NODE 111 (RANK=5262) What is the cause of this singularity error? This error is generated when matrix decomposition cannot progress any further due to the presence of singularities. […]
What is stress? Explanation with images
Stress Let’s start with something simple. Let’s visualize a pressure applied on an object. The pressure is causing a certain deformation to your object. After I applied the pressure, what is happening inside the object? Let’s assume the object is composed of a lot of smaller cubes. What is actually happening to one of the small […]
Pushover Analysis Tutorial with midas GEN as per Eurocode 8
Pushover analysis is one of the performance-based design methods, recently attracting practicing structural engineers engaged in the field of seismic design. The objective of a performance-based design is achieved after the owner and the designer collectively select a target performance for the structure in question. The engineer carries out the conventional design and subsequently performs […]
Reinforced concrete building Design Tutorial in midas GEN
This example problem is meant to demonstrate the design of a Reinforced Concrete building structure subjected to floor loads, wind loads and seismic loads. Seismic Design Data – Dual system (special reinforced concrete structural walls with special moment frame) in the transverse direction – Special moment frame in the longitudinal direction – Assigned to a […]

![[Beginner Tutorial] 2 Bay Frame tutorial in midas GEN](https://feaforall.com/wp-content/uploads/2016/03/2-bay-frame.jpg)
This example is for those who never had an access to midas Gen previously. Follow all of the steps from the modeling to the interpretation of analysis results for a 3–D simple 2–bay frame to get acquainted with the process. This is the first tutorial of midas GEN. The tutorial in paper form is extremely […]
Introduction to Stress Linearization
In the finite element method, when structural elements are used in an analysis, the total stress distribution is obtained. Therefore, to produce membrane and bending stresses, the total stress distribution shall be linearized on a stress component basis and used to calculate the equivalent stresses. If shell elements (shell theory) are used, then the membrane […]
