Dear respected members,

The staad example shows in the definition of seismic load as "joint weight", can any one show me how to calculate the joint weight of the structure.

I have calculated the seismic design load manually and then applied on nodes at

different level and by staad seismic load generation. I found vast difference in value of loading as can be seen in the two different uploaded files.

My procedure for seismic load generation is, 1. self weight of structure 2. member weight, which includes weight of brick/ block walling 3. floor load which includes 50% live load.. Is this correct way of load generation. If yes, then wat will happen to dead (beam, slab, shear wall,column) load. How will we define this dead load in staad.

So, the summary of my questions is;

**How can we calculate joint weight of structure (for seismic load definition).**

After going through my attached files;

**Why is this big difference of seismic design loading in my attached models.****what is the correct way of defining seismic loading.****is the process of my seismic load generation correct.**

Waiting for early response.

Regards,
