The document outlines the steps to analyze a floor slab using Idea Ws Slab software, including defining the slab outline and openings, adding internal nodes and lines of support, creating load cases and combinations, running the analysis, checking reinforcement requirements, and exporting the results. The process involves setting project parameters, modeling the slab geometry and supports, applying loads, running calculations, checking reinforcement at positions, and generating output files for further review or export.

1. Idea Ws Slab analysis of the floor slab and check according to EC2 http://www.idea-rs.com/ideastatica

2. Creating of the new project and definition of the project data 1. Create a new new project 2. Specify material and thickness of the slab

3. Definition of the outline of the slab 1. Button for adding/removing nodes of the outline polygon 2. Specification of the nodal suports

4. Definition of opening 1. Create/delete an opening 2. Adding/removing nodes of the polygon which defines the shape of the opening 3. Specification of the support in nodes or on lines

5. Input of internal nodes Adding of a new node Removing of the existing node Type of the support in the node

6. Input of internal lines Create a new line Delete the existing line Type of the support on the line

7. Definition of load cases Create a new loadcase Type of the load case – it can be pernament or variable Uniform loading on the surface of the slab

8. Definition of load impulses in load cases Create a new impulse Type of the impulse Area where impuls is acting

9. Definition of load combinations Set load coefficients for load cases in the load combination Typo of the combination Create a new combination

10. Running of the analysis and showing of results Run analyisis Choose load combination Choose type of the internal force

11. Division of the slab into areas which have the same type of the reinforcement There are defined two types of the reinforcement in this example. A type 1 in green areas and a type 2 in orange areas.

12. Definition of check positions Create a new position The type of the definition of the check position (node, node of the mesh, mesh element) Specify the required type of the reinforcement in the position

13. Creating of the Idea Rcs project Button for generation Rcs project (performance is going to be improved) List of extremes in the check positions

14. Opening of the generated project in Idea Rcs The list of the check positions (sections) on the slab The type of the reinforcement in the section The list of the extremes belonging the the check position (section) Values of the selected extreme

15. Input of the real reinforcement for types of the reinforcement which were defined in Ws Slab Template of the reinforcement – input of parameters

16. Table of check results for all sections Limiting check values in the check postions (sections) Check values for extremes

17. Preview of the calculation protocol

18. Possible export to Idea ProDesign Create project file for ProDesign
