I would like to design a bollard (and its sonotube footing)to behave as a guardrail in a parking lot... essentially, for a horizontal force of 5kips @ 2 ft above ground. I'm using a 6"OD pipe embedded into a 24" sonotube (4.5 ft deep in the ground).
Is there a code for bollards, or using...
Can anyone direct me to a website containing shear capacities of self-tapping screws for a shear load ±13kips (58KN) joining a 12Ga with 1/8 steel plate?
Second question: if I were to use these screws as a means for fastening rather than welding for full composite action shear connection...
Using Limit State Design (or other) how doe you arrive the quadratic equation to determine the exact location og the N.A. (ie center of gravity) for a typical 100mm (4") concrete overlying on a C10x3½x0.105 (12Ga) purlin?
bc(x2)/2 = n As (tc + ds - x)
