Study of Constructive Arrangements for Realization of LCC (Local Crisis Centers) and Analysis of Implemented Safety Measures

As part of his graduation thesis at Demathieu Bard, Mr. Adjehi used the structural FEA software RFEM 6 as well as the Concrete Design add-on.

Author	M. Adjehi
University	ESTP Paris, France

After the Fukushima accident in 2011 caused by multiple earthquakes, EDF decided to equip its French nuclear plant with LCCs (Local Crisis Centers). The project is also part of the ASN's plan to extend the useful life of nuclear power plants by a minimum of 10 years, and of the decision of Europe, and especially of France, to revive the nuclear industry. Demathieu Bard, as a member of a consortium, is responsible for the design and construction of 17 new LCCs for EDF, with the delivery of all LCCs scheduled by 2026.

As part of his graduation thesis at Demathieu Bard, Mr. Adjehi used the structural FEA software RFEM 6 as well as the Concrete Design add-on. The study project is the construction of a LCC for the Cottenom power plant in eastern France. The structure is a world first of its type, consisting of a bunkerized building with a surface area of around 1,250 m², built entirely of reinforced concrete on one level.

Knowledge Base Articles

Using an example of a steel fiber-reinforced concrete slab, this article describes how the use of different integration methods and of a different number of integration points affects the calculation result.

In order to correctly design a downstand beam or a T-beam in RFEM 6 using the Concrete Design add-on, it is essential to determine the flange widths for the rib members. This article describes the input options for a two-span beam and the calculation of the flange dimensions according to EN 1992-1-1.

KB 001838 | Design of Ribs, Folded Plate Structures, and Surfaces Using Result Members

If you want to use a pure surface model, for example, when determining the internal forces and moments, but the structural component is still designed on the member model, you can take advantage of a result beam.

KB 001796 | Shear Resistance According to ACI 318-19 in RFEM 6

With the most recent ACI 318-19 standard, the long-term relationship to determine the concrete shear resistance, V_c, is redefined. With the new method, the member height, the longitudinal reinforcement ratio, and the normal stress now influence the shear strength, V_c. This article describes the shear design updates, and the application is demonstrated with an example.

Product Features

Feature 002670 | Fatigue Design According to EN 1992-1-1, Chapter 6.8

With the Concrete Design add-on, you can perform the fatigue design of members and surfaces according to EN 1992‑1‑1, Chapter 6.8.

For the fatigue design, you can optionally select two methods or design levels in the design configurations:

Design Level 1: Simplified design according to 6.8.6 and 6.8.7(2): The simplified design is performed for frequent action combinations according to EN 1992‑1‑1, Chapter 6.8.6 (2), and EN 1990, Eq. (6.15b) with the traffic loads relevant in the serviceability state. A maximum stress range according to 6.8.6 is designed for the reinforcing steel. The concrete compressive stress is determined by means of the upper and lower allowable stress according to 6.8.7(2).
Design Level 2: Design of damage equivalent stress acc. to 6.8.5 and 6.8.7(1) (simplified fatigue design): The design using damage equivalent stress ranges is performed for the fatigue combination according to EN 1992‑1‑1, Chapter 6.8.3, Eq. (6.69) with the specifically defined cyclic action Q_fat.

Feature 002671 | Seismic Design of Reinforced Concrete Members According to EC 8

The Concrete Design add-on allows you to perform the seismic design of reinforced concrete members according to EC 8. This includes, among other things, the following functionalities:

Seismic design configurations
Differentiation of the ductility classes DCL, DCM, DCH
Option to transfer the behavior factor from a dynamic analysis
Check of the limit value for the behavior factor
Capacity design checks of "Strong column - weak beam"
Detailing and particular rules for curvature ductility factor
Detailing and particular rules for local ductility

Feature 002654 | Design of Fiber-Reinforced Concrete

The Concrete Design add-on allows you to design fiber-reinforced concrete components according to the guideline "DAfStb Steel Fiber-Reinforced Concrete".

You can use this option for the design according to EN 1992‑1‑1. The design according to the DAfStb guideline is carried out once the concrete of the "Fiber Concrete" type has been assigned to the reinforced structural component.

Feature 002652 | "Crosstie" Reinforcement Option for Design According to EN 1992-1-1

In the "Shear Reinforcement" tab, you can select the option "Cross-ties over free rebars with active selection in graphic". It allows you to arrange additional cross-ties on free rebars of the longitudinal reinforcement.

You can activate or deactivate the position of the cross-ties in the Info Graphic. The cross-ties are applied for the ultimate limit state design and the structural design checks. They are available for the design according to EN 1992‑1‑1.
