Thank you very much for the reply.
My building has an "extreme torsional irregularity" (type 1b) and a "reentrant corner irregularity" (type 2). The reentrant corner irregularity is making the building to twist drastically along the CR axis. This is the reason why the building is having an...
Hi,
I am having a hard time trying to understand how to determine the design story drifts of a RC building using ASCE 7-10. The building belongs to Seismic Design Category C. Section 12.8.6 (ASCE 7-10) deals with story drift determination and states that:
For me, seismic design forces are...
Thanks all of you to reply. I think, this should be the definition of an "essentially complete space frame", after reading many papers and documents on the subject... (however, none of them explained what an essentially complete space frame meant).
An essentially complete space frame is a space...
gobsmacked, thanks for the reply.
This is what I found in the internet ( http://www.structuremag.org/article.aspx?articleid=853 ):
According to the author, that definition can be found here:
ATC (Applied Technology Council) (1978). Tentative Provisions for the Development of Seismic...
Hi there,
What does mean an essentially complete space frame? I know what a space frame means, but how to interpret the qualifier "essentially complete"?
In context, this is what ASCE 7-10 prescribes in page 59:
Thank you!
Dear avscorreia,
Thank you very much for reply. This is a table in which you can get the global coordinates of the internal joints. However, how can I know which is which. As an example, how can I get the global coordinates of the joint tagged with "(1785)"?
Thank you!
Dear ETABS Community,
In ETABS, how can I get the coordinates of joints tagged with parentheses?
For example, because of the meshing in shell slabs, some joints need to be created internally by ETABS in order to produce the sub-shells. I was wondering whether we can get the coordinates of...
Hi there,
I am analyzing and designing a 4-Story RC Building with ETABS 9.7.2. I have a question regarding how the design positive moment is computed at the middle of the beam by ETABS. For example, according to the "Concrete Design Information ACI 318-08/IBC 2009" window (shown below), the...
Hi there,
I am analyzing and designing a 4-Story RC Building with ETABS 9.7.2. I have a question regarding how the factored positive moment is computed at the middle of the beam when designing with ETABS. For example, according to the "Concrete Design Information ACI 318-08/IBC 2009" window...
