Yeah, Pakistan Building code is being used, but only for seismic zoning determination, as far as I know. May be someone, somewhere is using it for more. Its mostly based on UBC97 provisions, which is an obsolete code internationally. It was to be updated in 2014-15, I think, but nothing is being done. As, us, as a nation need disasters like oct 2005 to wake up.
@Ayesha Etabs is not, not the "best structural software on planet". There are plenty of other software's out there, with way better interfaces, results accuracy and reporting methods then Etabs.
