Unloading Area of Industrial Site in Isère, France
Customer Project
The engineering office Études Techniques Lyonnaises was commissioned with the structural design of the foundations for a new unloading area of an industrial site in the department of Isère, France.The new unloading area consists of a steel structure built on a foundation plate. The total area is divided into two parts: a traffic and unloading area for rail vehicles, and an area with a pit and a traffic zone for lift trucks.

Structure
The reinforced concrete floor slab absorbs the loads from the 16 columns of the steel structure and is supported by 41 bored piles. Several different load types (live loads, snow loads, wind loads, and seismic loads) were applied to the floor slab during the calculation.
In the pit area, the filling loads were applied to the foundation plate. In the running area of the rail vehicles, moving loads were generated with the help of the RF-MOVE Surfaces add-on module. A total of 40 load cases were applied for the design of the floor slab. After the automatic generation of load combinations, the filter settings kept only the most relevant ones.
Foundation Plate and Modeling
The foundation slab, with a length of 102.4 ft and a width of 36.2 ft, was modeled as a surface element.
Loads from the steel structure were applied as nodal loads to the foundation heads, while elastic supports represent the bored piles in RFEM. The RFEM feature "Elastic Support via Column in Z" allowed for the adjustment of the FE mesh at the pile heads.
To generate the moving loads due to rail vehicles, it was necessary to define the position of the axes, the loading, and the direction of the rail vehicles in RF‑MOVE Surfaces. Based on the data entered, the add-on module generated several load cases automatically.

Slab-Wall Connections in RFEM 6
The properties of the connection between a reinforced concrete slab and a masonry wall can be correctly considered in the modeling using a special line hinge that is available in RFEM 6. This article will show you how to define this type of hinge by using a practical example.

I received an error message “Surface of incompatible type... (Surface in upper plane of building story must be of ‘Load transfer’ type)” when running the calculation. What is the reason?
- How can I efficiently define line hinges on several surfaces?
- My live load is less than or equal to 100 psf. How do I consider the reduced load factor in the ASCE 7 load combinations?
- I do not see the seismic load cases in my generated ASCE 7 load combinations (COs). How do I add them?
- How do I create an imperfection based on a mode shape in RFEM 6?

How do I apply the ASCE 7 Orthogonal Directional Combination procedure (100% + 30% rule) to my seismic load in a static analysis?
- Why does the load wizard "Member Load from Area Load" give unnecessary concentrated loads?
