Hi Folks, I am doing a hand calculation to find the percentage loading in 4 lift padeyes on a structure which is 2000mm L x 1500mm W x 1200mm H. Attached image shows a structure with the COG exactly in the center. This would then have a percentage load on each liftpoints/padeye as 0.25 (which...

Hi All, I am trying to find some reference for combined stress calculation in a pin, in AISC 360-10. Can someone guide me to the correct section please? The pin in question is a circular pin used in a clevis, and we have the result values of Axial and Shear Force on the pin with a beam...

Hi All, I did an analysis on a equipment. The equipment is welded to the ground plate at 16 points/Nodes (N1, N2...N16). The analysis under 3 different loading scenarios give 3 outputs as attached. I am doing some hand calculations for welding at these nodes. The TOTAL LOAD (highlighted in...

Hi All, I have attached a sketch of a welded structure, with 4 gusset plates. The structural analysis program shows the loads in the X, Y and Z direction at the beam intersection. I know it might sound basic stuff for many of you, can anyone advise what is Equivalent Stress for the welding of...

Hi All, I am trying to do an analysis on a structure, where some part has pipe to pipe connection (bolted with flanges). The structural beam analysis software I am using does not allow to model flanges or bolts. So the flange joint can only be input as beams with a node joint, and I will have...

Hi All, If we want to make a circular hole and a rectangular hole in an loaded I-Beam, which place is best place to put the holes (Center/or at beam ends, and mid-web/or near flange ends), so that there is the least stress in the beam near the opening. One beam is point loaded in the center...

Hi All, For FEA, simulation work which computer specification would be better? A computer with processor i7 4790K, 4GHz, 4 Core, 8 Threads, 32 GB RAM or a computer with Processor i7 5930K, 3.5GHz, 6 Core, 12 Threads, 64 GB RAM. Thanks in advance, HD

Hi All, I normally save SolidWorks drawings to .dwg format. While opening I use Draftsight for .dwg files. But when the drawings are saved in the .dwg format, the drawings are all bigger than the paper size (around 5-6 times the paper size). The drawing size is correct, which is A3 size. But...

Hi All, I am designing a structure with a final load of 25 tonnes. While I have designed lifting padeyes in the past where padeyes have been slotted through tubes (circular, square, and rectangular). This case is the padeye is to be welded on a I-Beam, but instead of just welding it with a full...

Hi All, I am designing a subsea equipment, which will be using a foam block to make the equipment neutrally buoyant. While we can calculate the buoyant force needed to make the equipment neutrally buoyant in seawater, I have another question. Suppose the equipment is neutrally buoyant in water...

Hi All, I am designing and analyzing a container frame 20' x 8' x 8'. As per DNV 2.7-1 guidelines, the equivalent von Mises stress is not to exceed 0.85 of the yield stress of the material. Now as I am doing a beam/column analysis in my software the output stress is only in axial, shear, or...

Hi All, I am trying to design some new hydraulic tools where pressure will range from 1000 psi to 15000 psi. I am familiar with Swagelok and Parker. My question is what fitting standard should I stick to for my Marine and offshore products? I want to stick to one commonly used and available...

Hi All, I am designing a winch, which would have a drum weight of 2000 kg, and wire rope of around 4500 kg wrapped on the drum. I need to find the torque required to rotate the drum from rest. Is there any literature or reference I can refer/read to? Thanks in advance. Regards, HD

Hi, We have a 12 ft W Beam running in our workshop, with a 2 ton trolley running in it. Everything is rated for a WLL 2 ton. The W Beam is welded across to the transverse beams above it. All the transverse beams make up the roof of the structure, and all the transverse beams are placed at a...

Hi All, Is it possible to find the flow rate from Pressure and Pipe ID? I need to find the flow rate for a pressure of 2000 psi, with a pipe ID of 0.25 in. Thanks, HD

Hi All, I am trying to figure out the actual stress distribution on a weld length. In traditional calculation, one can just divide the load by the weld area to find the stress. But consider the attached scenario (see attached), the load is on one corner of the beam (towards extreme left). The...

Hi All, I am doing an analysis in STAAD.Pro for a container. The container is modeled and lifted with four lifting slings. To stabilise the model, normally springs are used at the bottom in horizontal planes at the four corners. This is a 25 Metric Tonne container. There are 8 springs in total...

Hi All, I am preparing a excel sheet, where I have the results for an analysis. I have the stresses for Axial, Bend-Y, Bend-Z, Combined, Shear-Y and Shear-Z. What formula do I need to come up with for the von-Mises stress? Thanks in advance. HD

Hi All, I am designing a truss structure which will see an equipment of 60 Tonnes sitting on it. I have done the analysis and everything is fine. While modeling the truss structure, I am not being able to make a proper joint for the diagonal brace. Please see attached picture. The joint is made...
