Simple. The wall load on the beam is calculated as follows; Selfweight of 225mm cellular blockwork for lightweight aggregate = 2.87kN/m² (Ref: BS 648), Self weight of 13mm thick wall rendering on both sides = 0.3kN/m² (1:3 mortar mix, Ref: BS 648) ∴ total weight equals 2.87 + (0.3x2) = 3.47kN/m². But height of wall on beams = 3.15m , therefore it then follows mathematically that the distributed wall load on the beam = 3.47x3.15 = 10.931kN/m. Detailed information is contained in the spreadsheet to be supplied on request

Provide your email address and we shall provide the explicit load calculation sheet I derived for the purpose of this analysis

Yes I do. Comprehensive analysis with STAAD inclusive of bridge free vibration analysis as per EN code of practice

@@ShediConsultLtd how do i enrolled and how much?

send an email to us at ([email protected]), specifying your country of residence and we shall provide a detailed response based on the specifics of your request.

Provide your email address in a response here and you shall get the staad file

Yes it is available. Just make your request

Sure you can. Send in your email address

Thank you very much

I hope the video makes sense to you? Send your email address and I shall send you the staad analysis file

Yes this structural design can be done. But the connections would have to be designed as full strength and rigid and the rafters would have to be plastic sections in order to ensure the formation of rotational hinges and moment redistribution due to the span of the portal frame

The derivation of the dynamic blast pressures (from a FERA), shock front pressure, reflected overpressures and the decayed stagnation pressures were clearly derived in the video. It is not the intention to completely carry out a blast analysis of the wall using the time-dependent impulsive forces, etc as this is a sensitive topic

@@goldgateengineering I'll appreciate if I can get the staad file as well and a video of how the vehicular loads were applied. Thank you very much

Yes we do have. The video is currently published on this page

Structural Member strengthening is a process of enhancing the cross-section of a member to improve its moment capacity, shear capacity or a combination of both. This can be achieved by the use of flange plates, wing plates or load bearing stiffeners or their combination. For an I-section for e.g, addition of flange plates typical thickness of plates on the flanges will increase the moment of inertia about the major principal axis of the section by the product of twice the cross-sectional area of the plates and the square of the perpendicular distance of the centroid of the plate to the centroid of the section.

@@goldgateengineering thanks😊

This is a multiple degree of freedom blast analysis which was performed as a first order dynamic analysis and a 3-dimensional finite element analysis is best suited to extract the response of the structure to impulsive short duration loads

Thanks for the feedback, kindly refer to Table 2.2 on Eurocode 1:3 for the load combinations to be catered for in the crane girder analysis. Also refer to Table 2.6 for the values of the dynamic factors to be used.

U cant generate crane loads automatically as the wheel loads from the crane unto the girders are either calculated based on d minimum hook approach, end carriage wheel centres, weight of crab and crane bridge. Conversely these can also be provided by the vendor as shown in d video

For the design of the wall and base of the culvert, the bending moment distribution diagram at the base as a result of the design earth pressure caused by the factored characteristic forces shall be used in the design of the base of the culvert against flexure. The walls of the culvert also shall be designed against hogging bending moment caused by the combination of the design critical load cases causing lateral stresses on the walls of the culvert.

Thanks for the feedback. kindly share the video with your fellow engineers

Simple, the moments and forces from the superstructure corresponding to the nodes shall be exported from staad using the reaction list...these are the forces that shall be applied at the corresponding columns of the raft foundation.

The grane girder is modelled from bracket to bracket with adequate moment releases to cater for joint rotation at the bracket...the weight of the crane rails is very insignificant and is catered for by selfweight contingencies. The load combinations cater for dead loads with associated crane actions and the partial factors of safeties applied to the dead selfweight of the crane girder caters for that of the grane rails

@@goldgateengineering thank you for your reply. Okay, for the moment releases, it's about Mx and Mz axes right?

@@michaelzcun No, the moment release for the crane girder is about the local Z-axis only which implies Mz

Send ur email and we will respond to you. Due to the sensitive nature of this type of analysis we prefer a directed response

i need to know too

Thanks for dropping a comment. The soil pressure is not modelled in the course of analysis, rather the soil restraint which is based on Wrinkler's theory. The results of the analysis will provide the contact earth pressure which shall be reported by staad

Ok, thanks for the good work. What about the support assignment to the raft beam, this is not mentioned in your course?

@@sikiruyusuff1246 The same same support spring for the raft slab is applied to the corresponding beam bounding the slab..The load transfer mechanism is from the raft slab unto the raft beams via the contact earth pressure distribution beneath the raft
