Thank you all
First, Mr. Oldestguy, I have not double-edited; I was surprised to see a message from Mr. Ramakrishna Das, with whom I totally agree. The seismic force calculated by the code does not depend on the type of structure that is being analyzed. It depends on whether of the 5 factors...
Thanks for your responses, they have been very helpful.
I understand that:
The design spectrum or soil acceleration diagram Vs Periods is made without considering the type of structure to be built in it locally, it is a dynamic response characteristic of the site and depends on the periods of...
Dear Engineers,
I will like to know if some of you have designed structures according ASCE 7 outside USA.
In this case is necessary to get the factors SD1, SD2, Ss ,etc for that country.
I found in API 650 2018 section EC-4.3 “ Sites not defined by ASCE7 methods” a vey simple an practical...

fattahma7,
May be you modeled yor "chimney", with Autocad, and is possible that there is an imprecition in your drawing, that means the frames that you want to divide are in different planes. Try to use a merge joints option or check your model.
Dear ELSarwan,
I Think ( and I allways do), you must check the "k" values used by SAP and the effective unbraced lengths. For me, SAP is my assistant, I work as if I were doing the calculation by hand. For the bottom chord of your truss, you have two lengths. In the plane of the truss, "lx" is...
Dear cfgil,
Include the self weight of the entire system.
All the elements modeled in the DEAD case are affected with "1.0" or the self weigth is included.
Gentleman,
I will like to know how to apply a load like:
q = 300t, where t is time. When apply this load the program in assign uniform loads , the progrman does not give the option to apply it.
There is another way to applied it?
Thanks in advance
Friends,
May be some of you have used the book " Bucket Wheel Excavators" by Durst and Vogt . I am currently engaged in the structural design of mechanical equipments, Conveyors, reclaimers, etc. Only the structure. This book is allways a reference in all papers and articles I read. I was...
Hi,
You need to say to SAP if the column is restrained to lateral movement or not. If your column is braced, then is not sway, if not , is sway. But you need to analize the the structure if it can move or not from the point of view of engineering, SAP do not make this kind of decition. Test...
