"**WARNING: IF THIS UBC/IBC ANALYSIS HAS TENSION/COMPRESSION OR REPEAT LOAD OR RE-ANALYSIS OR SELECT OPTIMIZE, THEN EACH UBC/IBC CASE SHOULD BE FOLLOWED BY PERFORM ANALYSIS & CHANGE."
I did not understand anything from that warning but it contd to analize the structure. I wanna ask you that is my seismic analysis correct?
P.s: I entered 0.8s period values on purpose. And i know my modal analysis is wrong.
I'm new with STAAD and i'm using 2005. I'm having trouble with some errors and i do not know how to correct them :
1. "... if the UBC/IBC has tension/compression.. " - Error notice
2. " density not provided, self weight ignored.. "
Please enlighten me on these errors, What does it mean and How do I correct it ?
It worked perfectly THANK YOU !!!!. :-)
Hmmmm... now i'm into slab. It keeps failing.
first, i made a 0.18m thick slab and assigned it to the most critical slab surface in my structure.
then I designed it with the following properties : fc=20700kn/sqm fyld=276000Kn/sqm bars from D10-d12
I chose max. moment for the design, and selected DL and LL for loadings
The span is only 3m by 4m, i even tried 2m x 3 m span and it keeps failing. Is there something i should look into to correct this failure ?
