Etabs Modelling

[vicky13790]

Hello everyone,

I need some clarifications in Etabs modelling. How do i apply lateral loads (EQ) in etabs manually? What's the difference between lump lateral mass at storey level and include lateral mass only of mass source in DEFINE? Which option i should check when i enter the EQ loads manually. I m pretty much done with modelling except the application of lateral loads. I indeed applied the lateral loads as user options in static load case (applied @ COM). When i analysed the structure shows the vertical loads and also the user defined horizontal lateral loads @COM. The EQ lateral load application is kind of tricky in etabs. Kindly, help me out in solving this issue.

Your manual application of EQ load, is OK.

For clarifications regarding defining & proper application of mass source in ETABS, you may refer to following links:

A good structural engineer is often a blessing for others.
