SESAM User Course GeniE Workshop: A quick introduction to punching shear, member and plate code checking

•

To learn new users how to model a structure and apply loads and boundary conditions to do Joint modelling (cans, stubs, cones) and tubular punching shear check Member code check and re-design Plate code check based on the PULS standard

•

The structure and loads are highly fictitious as the main purpose is to give a quick introduction to modelling and code checking in one simple model that you can model within a few hours. Program defaults are used for all code check runs

•

If this is your first exposure to GeniE you should do the tutorial B1- A small introduction to GeniE

Program versions You need GeniE version D5.3-07 or later. This tutorial can be executed from GeniE.lite except for the plate code checking. If you have the full version of GeniE your license file must include code checking for beams and plates as well as structural analysis. You can recreate this workshop (except the report creation) by making a new workspace and importing the file B10_in.js. If you want to recreate the structure and the loads only you can use the file B10_clean.js

2. Start by defining section properties. For this tutorial you will need the following section types: L-profiles: Jap_L150x90x9x9, Jap_L200x90x9x14 & Jap_L250x90x10x15 T-bar: Tbar425x120x12x25 & Tbar630x150x12x30 I-bar: HEA140A, HEA200A, HEA240A Pipe OD406.4x10, OD508x10, OD610x10, OD813x10 All the sections can be imported from the section library.
