Maybe ACI code can help as under,

Adding my cent, Basically R ductility factor and detailing of the structure matters, due to greater ductility demand in higher seismic zones 3,4, R value is high also detailing requirement is high to make the structure capable to dissipate energy. UBC defines some restrictions as per different zones, in 2B IMRF minimum, and zone 3,4 SMRF. in 2B SMRF can be designed but in 3,4 it will be too uneconomical. we can violate code but for that greater effort for design is required, have to go for performance based design but it is better to hide behind the code.

Waqar, You post is excellent and this is something that I believe the law makers can address. The overall labour laws in the country are worst by any standards. Have you tried contacting the MNA in your area. I believe that is Asad Umer. Thanks.
