I have been designing a concrete ballast block for a subsea pipeline (flexible PE Pipeline with 1.8m dia SDR 26). As I understand, during installation and operation , there will be some deformation /ovalling of the pipeline owing to the below conditions. * Bending of the pipes during lifting...

Hello All, Anyone have idea about available Post Graduate Diploma Course related to marine, coastal or port and harbor structure engineering which can be attended online or self paced with occasional visits to campus. In Europe, Middle or South Asia? Thanks for your help

It didn't pass. I was worried about the deflection before. However, upon considering the welded alloy properties, it fails in the flexural strength and deflection seems okay as the elastic modulus can be considered as the same. The allowable strength for flexural compression reduced to 6.5 ksi...

Thank you all for the response. This circular rod section is in fact proposed by the client for the hand rail support posts with welding to the base plate. I have to verify and give them a verdict whether it is feasible or not. phamENG, I referred the aluminum design manual. Although it...

Dear All, I have been involved in the verification of a cantilever aluminum rod of 45mm diameter which shall be subjected to a lateral force and subsequent moment. The end of the rod is proposed as welded to the base plate by fillet weld by a client. I understand that aluminum will be...

Hello Desertfox, I missed to show the sideway forces in the opening post. However, the question I have asked is mentioned by ProgrammingPE.

Hello Dik, I understand that the directionality shall be ignored in the case of HSS members welding as per AISC. I saw the reference in Section J3.4.2 of AISC 360. But I think the directional method in BS EN 1993-1-8 Section 4.5.3.2 is different from the AISC 360's the directional strength...

Thanks desertfox for the reference. The reference which is based on the AISC code mainly mention two methods; Instantaneous Center of Rotation Method and Elastic Method. Considering the elastic method, for forces normal to the faying surface, the shear and tension forces can be summed...

Thanks GaryHStr, I understand this is not a straightaway easy method to calculate the stresses accurately. However, do you have any chance some text or journal references to see this method in detail.?

Good Day All, I have a doubt regarding the computation of weld stresses using the directional method of Eurocode 3- Part 8. How we can distribute a vertical force as shown in the picture into shear stress and normal stresses? As I understand a portion of the forces will be carried by vertical...

Hello All, I have been trying to verify a spreader beam with a double channel built-up section with batten plate as connectors between the channels as shown in the following figure. The beam is subjected to axial compression force and bending moments. As I read from the codes and forums, the...

human909 I am just planning to provide two horizontal fin plates to connect with the top and bottom flanges of the beam to be able to carry the transverse shear from the bracing forces (as shown in the figure). The bracing forces are applied to the joint as horizontal and axial force components...

I have a doubt (which is very elementary) on a connection type for an eccentrically connected horizontal bracing to a beam. As shown in the below figure, the horizontal bracing is connected to the beam-column joint with an eccentricity of about a dimension equal to the depth of the beam (say...

Referring to CANPRO's idea statica report, I happened to have a doubt about the bending moment you have additionally applied. As I understand idea statica considers the eccentricity ( (B+t)/2 ) by itself. Even if we do not apply the additional moment, idea statica evaluates the bending moment...

Thank you gentlemen for pointing to the very right place where it is discussed in detail.

Greetings. As shown in the attached figure, I have been checking a column beam brace connection. In my case, the brace member is a TEE section made from UB sections. The line of action of the axial force in the brace member is acting along the centroid of the TEE section which is at a distance...

Thanks KootK. I will use the 0.6x compression force for finding the resistance considering the surface is not intentionally roughened and for the remaining shear I will provide shear friction rebar.

Hello All, I have been checking the interface shear strength between a precast block and the cast in-situ concrete portion above it for a gravity retaining wall as per ACI 318-14. I have a doubt about the shear strength and whether it is okay to consider section 16.4.4.1 as it is for the...

Hello All, I am involved in the design of curtain wall panels for a multistorey building where the contractor intends to use perforated UHPC (Ultra High Performance Concrete) panels as the wall panel. The panel shall be made of unreinforced UHPC concrete with a minimum compressive strength of...
