2.then create a box section in hyper beam by going through model - hyper beam - create - standard section - hypermesh - box section - apply dimensions a , b and t.
3.create a component with suitable name for giving property and material in the model box.
4.then create a rod element between the RBE2 links.for that go to 1D - rods - select nodes - element type - CROD.
5.create a property with suitable name in the model box for applying card image , material and beam section.
6.create the property in the prperty option in horizontal tool bar.for that - go to property - property name - type - 1D -card image -PROD -material - steel - create.
7.assign the property and material for the componenet in model box.
8.assign the card image as PROD,material as steel and beam section as box section in the property created in model box.
9.enable the 1D detailed element representation then the section is appeared.
b.beam element
1.create the RBE3 link on the the proper areas that is boath lower and upper brackets by goig through the option, 1D - RBE3 - select the nodes -apply proper DOF - element type as RBE3 - create.
2.then create a I section beam in hyper beam by going through model - hyper beam - create - standard section - hypermesh - i section - apply dimensions a,b,c,t1,t2,t3.
3.create a component with suitable name for giving property and material in the model box.
4.then create a rod element between the RBE3 links.for that go to 1D - bars - select nodes - element type - CBEAM.
5.create a property with suitable name in the model box for applying card image , material and beam section.
6.create the property in the prperty option in horizontal tool bar.for that - go to property - property name - type - 1D -card image - PBEAM -material - steel - create.
7.assign the property and material for the componenet in model box.
8.assign the card image as PBEAM,material as steel and beam section as I section in the property created in model box.
9.enable the 1D detailed element representation then the I section is appeared.
c.bar element
1.create the RBE3 link on the the proper areas that is boath lower and upper brackets by goig through the option, 1D - RBE3 - select the nodes -apply proper DOF - element type as RBE3 - create.
