Hi guys
I have beam (beam 2) bolted to the underside of beam 1. Beam 1 is welded to a 30 mm plate which has 10 bolts (5 on either side) anchored into the rock above. The shear fore (V) is eccentric to the centroid of the bolt group, so it would put some bolts in tension. But i'm not worried...
Hi, what direction (clockwise or counter-clockwise) are the positive and negative bending moment values found in the results tables. Results are based on the global axes.
Ok, thank you. The pressure is from the impact force of the diverted gate in the chute. The force from the diverter gate is 18.82 kN. The force is exerted over a bump pad of dimensions 2x2 inches.
Deflections are small. So I assumed the left end of the highlighted region as fixed (where the stiffener is) and all other edges as simply supported. The max stress at the center of the fixed edge using Roark's was 31 MPa. I used the surface stress in Strand (not mid surface) and got a stress...
Hi, I just want to verify my stress results in my plate segments in Strand7 using Roark's formula. Should I use the surface (either -Z or +Z in terms of the plate's local axes. In this case the top of the plate is the -Z surface), or mid surface calculated stresses. So you would have either a...
Hey guys
So for example, if I have a 6m I-beam (beam 1) with a depth of 200mm (not including the flange thickness here) and I connect an adjacent beam (beam 2) with a full depth of 175mm to the center of the web of beam 1 at mid span, how effective would beam 2 be in reducing the laterally...
There is no lateral force acting on the structure, besides the notional load, to cause the member in the x-brace to be in tension and the other in compression. The brace is there to provide overall stability to the structure in the out of plane direction (but in the pic below, as I changed the...
That diagram is not the structure I am dealing with (I just put it in to show the type of connection at the intersection). The x-bracing configuration in my structure is in the horizontal plane.
Hi all
In case 1, both members are in compression. In case 2, both members are in tension.
What would the effective lengths in respect of the angle's principal axes be (Lz = minor axis and Lv = major axis) for the following single angle x-brace connection?:
Thank you
Hi guys, need some help on determining the effective throat thickness for the weld below (double bevel groove weld). I assumed the eff throat thickness to be similar to how you calculate it for a fillet weld. Pink area is the weld.
So I basically assumed point of rotation as the edge of the base plate, and determined the bolt forces for each row accordingly. Next step would be to calculate the effective widths of plate used to determine the section modulus. I have identified 3 effective widths highlighted in blue. Are...
Thank you ProgrammingPE. For the Tension force in bolt calculation, I've seen examples being used where they take the applied moment and divided it by the depth of the section.(this was for W/I sections though). This assumes point of rotation from the column flange. Therefore the bolts will...
thanks for the reply Dik. Just have some questions:
Why did you take distance S from the end of plate to the bolt? Won't the plate failure line be on the brown line as shown below, and then distance D will be from bolt to that brown line. Why did you take distance D as how you have it?
Thanks guys. If I remove the stiffeners and want to calculate the thickness, would I follow this process:
1. Calculate approximate tension force (Tb) to be taken by bolts = Mu/ angle leg width. The moment will be reduced by compression force Pu, but I will neglect it since its small value...
Hi guys
I have an angle section welded to an end plate which is bolted to a steel beam below (Bolts are centred on the plate). Unfortunately, due to geometric constraints, this is the layout I have to work with.
How would you go about determining the bending capacity of the plate. From...
