ASCE LOAD COMBINATION

[structural.engineer79]

Greeting

I attached five pictures, the first three pictures shown the load combinations explanation in ASCE code (Live roof and wind not included). the fourth and fifth for robot automatic load combinations and SDS value which is required for load combinations as per ASCE code. the program generate load combinations with some different (Like combinations 7,8,9 etc) also the vertical seismic load (0.2*SDS*D) its not considered in the robot combinations. any one can help regarding that. May be I have some missing definitions in programs.

Hi Mustafa,

Are you running some classes for US seismic design any time soon? I'd love to register 

Thank yo very much for your help.

Hello Mustafa,

I think you're familiar with american codes(UBC 97/ASCE 7) in terms of seismic load combinations.

I came across with documents showing a lists of load combinations as per UBC 97/ASCE 7-05(pls. see attached screenshots).

I notice that the factors they are using is quite different from their load combinations(the published documents is around 2007, probably they are using ASCE 7-05).

Also, it has load combinations for "serviceability" limit states about 7 load comb but I'm just wondering what's the basis for this.

I have a quick look at UBC 97/ASCE 7-05, and I cannot find it, it mostly deals with strength design combinations. Any thoughts on this?

Thanks Mr Mustafa

Please if it possible to attach one model in version 17 with load combinations according to ASCE for checking.
