I doubt anyone from the State will be available to address such minor things lol. My only remaining assumption about this would be that they used the modifier As-required/As-provided to reduce the development length. 
But regardless, thanks for helping me out with this. I think I'll go back to some textbook basics and see if I missed anything in there.  

Thank you @UmarMakhzumi and @Badar (BAZ) for your responses. I'll apply these to a problem I'm dealing with at the moment. I'll probably have some more questions as well so I'll be back again lol

AOA everyone. Recently I've been very confused with development length and how its provided in different components. I have a few conceptual confusions about it and then a few practical and design aspects of it. I'd really appreciate help on these.
Do we provide/check development length for simply supported beams (i.e. check it past the max moment?) Where do we need to check for development length? (in my understanding, we need to check it almost everywhere, where you need to ensure full moment capacity) What is a "critical section" when we talk about development length? (refer to the attached picture) I think its the point beyond which we need to ensure development At a wall-slab joint where both the slab and wall are 8" thick, if #6 bars at 8" c/c need to be developed from the slab into the wall, I found that even with the 90 degree hook, the development length is at least 14". How do you satisfy development length in such a case? For hooked development length ldh, is it the length up to the hook or is the length that includes the length of the hook? For example for a 90 degree hook, would it be 12db+the length beyond the critical section or just the length beyond the critical section up to the hook? I've seen in a few places on the internet that people include the 12db into the development length.  This stuff has been eating up gray matter from my brain for a few days now. Any help is appreciated.
Thanks!
 

@hali learn "anchorage" and "curtailment" rules for reinforcement of concrete structures. You will be there.

Culverts - first determine bending moment (tensile surfaces) and reinforce either one of two ways:
See hand sketch below - once you know moment and effective depth of tension reinforcement you can design the joint.
1. U-bars coming in from slab and wall and connecting in corner.
2. or, Top/outer bar bent around the joint.
3. Option 3 is to use L-bars at joint, 
- see sketch below for all three ways you can detail a culvert corner - your engineering judgement is determine which detail best suits your design!
Spacing of reinforcement tend to be closer to limit serviceability stress and hence crack width in concrete to <2mm - for reinforcement durability, and to stop water corroding the reinforcement, and to have a watertight structure; Movement joints are tricky in culverts. Make sure the concrete (or cement) selected is ok for, (i) against corrosive soils and (ii) chemicals in (waste) water.

I would suggest reading this book, as it has a lot of case studies on famous high rise buildings.
Structural Analysis and Design of Tall Buildings: Steel and Composite Construction - 1st Edition

One of the biggest life lessons that I have learned is on focusing what not to do, rather than focusing on what to do. As the great Molana Rumi said, The art of knowing is to know what to ignore.
I would suggest you to read about structural failures as that will shift your thinking to what should not be done. A good starting book would be - Why Structures Fall Down.
Thanks.

Thank you for letting me know Zain.

Please refer to this article by CSI on the topic.

Also there are SAP/ETABS tutorials on YouTube regarding the same. Following is a video on YouTube.
Hope this helps.

Hi Anton,
You need to create a free body diagram and do strength and deflection checks . For that, you will need some information from the architect like building plans to estimate mass per floor and structural framing drawings to idealize your structural for hand calcs.
Thanks.

Thank you Ayesha this will help!

Thanks Umar this will help (y)

Asalam-o-alikum wr wb everyone!
I am very excited to announce the launch of "Structural Engineering Forum of Pakistan". Its a open discussion forum directed to Civil/Structural Engineers. The purpose is to have discussions, to shun ambiguity and to overall uplift the structural design practice. I welcome everyone aboard. I hope this forum meets serves its purpose,
May Almighty ALLAH bless you all.
Warm Regards,
Makhzumi!
