Structural Eng: Find Deflection in Simply Supported Beam

AI Thread Summary
To find deflection in a simply supported beam with multiple point loads, superposition can be used by analyzing the response of the beam to each load individually and then summing the results. For quick manual calculations, software like Winbeam is recommended, which can calculate maximum moments and deflections if the stiffness factor is accurately input. While some users may not typically use Winbeam for deflection calculations, it is capable of doing so, especially with updated versions. If the beam has a constant cross-section and is one-dimensional, superposition remains a straightforward approach. Accurate calculations depend on correctly applying the principles of superposition and using reliable software tools.

How can i find deflection in simply supported beam with multiple point loads ?
 
Engineering news on Phys.org
Superposition
 
you can simply find the deflection for beam loaded with UDL, or you can put your load in the computerised model.
 
thanks for reply,
but what u will do when u have so many point load acting on beam
and u have to find solution manualy and quickly.
 
I would use the simple software Winbeam. This is an excellent tool for calculating max. moment etc. on beams with any kind of loadings. - Well, this can give the deflection, if the stiffness factor is correct inserted. Normally I don't use this program to calculate deflection - but it is possible as far as I know. I have a quite old version of the program - maybe a new version have even better features for calculating deflection.

Software? Computerized model? If the beam is 1d with constant cross section, then just use superposition.

You take the response of the beam based on each load seperately, then just add them together.
 

Thread 'Questions about the Tesla turbine'

Hi all, i have some questions about the tesla turbine: is a tesla turbine more efficient than a steam engine or a stirling engine ? about the discs of the tesla turbine warping because of the high speed rotations; does running the engine on a lower speed solve that or will the discs warp anyway after time ? what is the difference in efficiency between the tesla turbine running at high speed and running it at a lower speed ( as fast as possible but low enough to not warp de discs) and: i...

My water meter is submerged under water for about 95% of the year. Today I took a photograph of the inside of my water meter box because today is one of the rare days that my water meter is not submerged in water. Here is the photograph that I took of my water meter with the cover on: Here is a photograph I took of my water meter with the cover off: I edited the photograph to draw a red circle around a knob on my water meter. Is that knob that I drew a red circle around my meter...
