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.

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
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...
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...
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...
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...
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...
I have been reviewing an aluminium pedestrian bridge structure of 20m span and a width of 1.7m. The structure is composed of two warren type trusses and a platform for the movement (floor beams) that is connected to the truss's bottom chords as shown in the figure. The top chords are not...
Dear All,
I have been encountering some 1 and 2 storey building design. I have modelled the buildings in ETABS and applied the wind and earthquake loads. Also, I used the property modifiers for the elements as recommended in ACI 318.
My question is that when it comes to the design of the beams...
Hello Guys,
How do we can find the capacity of an angle section in carrying a uniform load on one of the leg while the other leg is bolted to a concrete wall at alternative spacing(say 500mm). I have attached a hand sketch for clarity.
Thanks for your help in advance
Hi All,
In precast beam-column moment connection, what are the best and economical methods to obtain the continuity of the bottom bar.
Thanks in Advance
Hi All,
I need to design a building with 100 m length with basement wall along the length. We cannot afford to provide an expansion joint in the basement wall. Could anyone explain that what all things I need to consider in the design of the wall. The wall is exposed to earth at one side and...
I was involving in the design of a three storey building the length of the building in the ground nd first floor is more than 80m and the length of the roof floor is 35 m. Although we are providing some insulation for the heat protection the temperature in the building location reaches up to 52...
Dear All,
I have been trying to design some cantilever beams for a 3 storey building using ETABS. As shown in attached figure, the cantilever span is 4.2m and the span of the slab supported on beam in other direction is 12m. I have applied the stiffness modifier for all other beams and slabs...
