Would you guys mind taking a look at these few code and structural questions. They come from a 3rd party source, which describes the correct answers, but still unclear to me. I'm not looking for a final answer from you, but rather evaluation of my line of thought - if I'm generally thinking in the right direction.
1. The following correct solution offers stairs at the ends of the building wings to avoid dead-end condition.
But I'm wondering if this will stair placement will cause very lengthy exit access travel distance from the middle of area B?
2. In the following correct solution exterior wall C does not need to be fire-rated.
I wonder why? This is IIIB type and bearing walls have to be 2hr rated per table 601.
If these exterior walls are not structural than they need to be rated per table 602 based on separation distance.
3. For the structural question below I do not understand why the answer "2-way slab"
can not be correct answer?
4. In the following structural question I do not understand why "beam with greater section modulus" can not be the correct answer also?
If the deflection is KL3/EI, section modulus is S=I/C or moment of inertia is I=SC, therefore deflection is KL3/ ESC. Which means that larger section modulus would also reduce deflection. Is it not correct?
