Hello engineers, Thanks you for your valuable points. The information regarding the deck slab which I mentioned in yesterday's attachment is incorrect. It is actually a 12" THK concrete slab w/ reinforcement. So I have enough depth to provide a good 6" embedment. My major concern was only the...

@JoelTXCive Yes you are right. Generally we design the railing w/ 200 lbs load. But per project spec, I have designed it w/ 250 lbs.

Hello jayrod12 ; I am the delegated design engineer. I got confirmation from the ARCH on the looks. It is fine for them. What I thought is, maybe I will distribute this 0.25 kips b/w 2 adjacent guardpickets,i.e., Shear= (0.25/2)*1.6= 0.2 kips; Moment= 0.2*42= 8.4 kip-in. When I check for this...

Hello fellow engineers, AISC design guide 34 I am designing base connection for a guardrail system. I apply 0.250 kips force on the top rail factored with 1.6 (LRFD), therefore 0.4 kips shear force on top rail. The height of my guardrail system is 42". So I get a moment of 0.4 X42 = 16.8 kip-in...
