My calculation for the baseplate capacity in the thread I have referenced:
(1) Calculate the bolt tension. I would use the lever arm from web of the 50SHS to the line of bolts.
e = 25 - 2.5 = 22.5mm (assuming 5mm wall)
M* = 3.2 x 0.4 = 1.28 kNm
T*b = 1.28/(0.0225x2) = 28.4...
Hi
Australian Standard AS4676 - Structural Design requirements for Utility Services Poles - includes an "informative" appendix on the design of piled foundations in soil, for a range of soil bearing capacities. Namely Appendix I. Footing designs for piled foundations are also tabulated.
The...
Hi
In checking an existing structure consisting of a concrete floor slab supported on steel beams (UB section secondary beams support slab, WB section primary beams support secondary beams, and concrete columns support the primary beams):
The typical frame for the primary structure = a...
Hi
My question is regarding the use of "allowable" lateral bearing stress in rock, in the case of a cantilever pile wall design.
The design scenario is a concrete pile wall (soldier pile, or contiguous pile) where the restraining material the piles are embedded into is rock (say Class V...
Hi
I am a structural engineer asking a soil mechanics question.
Not after an in-depth answer to the following.
Why is the ultimate capacity of cohesive soil to restrain a laterally loaded pile related to the Undrained shear strength of the soil?
EG, Broms Theory uses 9*Cu.
My basic...
Hi
Does anyone know whether the structural software "Robot" performs a critical buckling analysis of a 3D steel frame, and if so how the results and available output compares to the more familiar softwares such as Microstran or SpaceGass.
Not having spent a lot of time using Robot - I dont...
Hi
Anyone had experience (in large steel framed buildings) in utilizing the reserve compression (or tension) capacity of roof purlins (cold formed metal C's or Z's) as part of the roof bracing system for restraint against wind loads.
I have seen use of "battened purlins" - in lieu of typical...
