Rev. date 12 March 2011

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 quickintroduction 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 toGeniE

Program versions

You need GeniE version D5.3-07 or later. This tutorial can be executed fromGeniE.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

1. Start the program, create a new workspace (File|New Workspace) and name it Test.Let the units be in N and m.

2. Start by defining section properties. For this tutorial you will need the followingsection types:

L-profiles: Jap_L150x90x9x9, Jap_L200x90x9x14 & Jap_L250x90x10x15

T-bar: Tbar425x120x12x25 & Tbar630x150x12x30
