I think its time now to categorize questions based on the difficulty level. For example; A toddler asking very basic question like what is mass source or time period, should be classified under lets say Easy or 0 or Beginner or Simple etc category. And as such specific moderators should be assigned to take care of that forum. Then we can make other sections like moderate or difficult. Where one really need to relearn/review the question and think about the answer carefully. I think all the internet is full of the same basic questions like time period, base shear etc. Isnt it the time to take SEFP a step ahead and not just another forum full of the same basic questions? How can we re-categorize the SEFP sections to give it a new feel, not just like concrete, steel, software issues etc. What do you think?

Could you please explain that logic? Furthermore; seismic inter-story drift is limited to 2.5% of story height. If story height is 3.5m, the allowable inter-story drift is 87.5mm. If all floors were to be within the drift (so code requirements are satisfied) then a 10 story free standing building would have total roof drift of 87.5mmx10=87.5cm. Thats a lot, yes. But I do not see any limits in code for the seismic total drift as long as you have satisfied the inter-story drifts. Ofcourse, more the building overall drift, more will be p-delta effects, (that could be huge for a massive tall building). In wind design, overall drift is limited due to problem of acceleration at top floors. But in a seismic event, obviously human criteria is not something you should aim for.
