Hello,
What should i do in order to simply design my building for gravity loads.I am using the plate elements in my structure.How staad works out the loads from slab to beams?
hmmbe,
You asked if it is realistic to release a beam at just one end. A release is simply a reflection of the connection details at that joint. So, there should be no problem with a release at one end, if the connection at that end represents a condition which is different from the default.
sureshprsharma,
Using master-slave to prevent axial deformation sounds like a logical approach, provided the member also is parallel to one of the global axes. This is because the master-slave feature in STAAD allows for linkages to be along the global axes only.
Dear SKLOse,
I refer to your posting dtd. Mar 25 2011. Is it not possible to control the differential displacement of the two nodes of the beam in the local X direction with the help of Master Slave so that axial force is not developed in the beam?
Is it realistic to release the beam at one end ?
Is it due to the method of reporting of STAAD ?
The reason a beam develops an axial force is, the two ends of a beam move by different distances resulting in a relative displacement along the local X axis between the 2 ends. So, if you can prevent or minimize this relative deformation, the axial force can be prevented.
To achieve this, you'll either have to release FX at one end, or provide a very large value for AX (the cross section area). You can find a discussion on a similar topic at

Hi All,
When modeling like this, there is a large axial force in the beams, which is not realistic
How can we overcome this problem ?
