Hi, The wall is part of a large industrial building that has a structural steel frame but an external wall consisting of external masonry brickwork, cavity layer filled with insulation and internal facing blockwork.
My assumption that a 200mm circular penetration is okay because of previous...
Hi, is there any guidance or standards on the maximum circular hole size through masonry and concrete structures? I have been asked to confirm if a 200mm core through a masonry cavity wall is okay. Although a 200mm diameter core is okay as this is relatively small, what size of hole would not be...
A key advantage like some of you mention is to have space within the depth of the beam to run services through. This means there is no need to hang services below the beams and therefore you can have a larger open area or reduce the overall height of the building. The removal of the weight can...
Hi, I have a design of a wall bracket that consists of a 40mm thick MS plate that will be bolted to an R.C. wall using resin anchors. A UB section is rotated 90degrees on its side and welded to this wall plate in addition to a stiffener plate below that at the centre. The wall plate forms part...
Hi All,
@human909 - that is my concern that we cannot consider the plate as 100% fixed. Simply support is a conservative assumption but in reality we need to somehow look somewhere in the middle...
@GeorgeTheCivilEngineer - The steelwork floor is existing, the original calculations show the...
Hi, thank you for the reply. The floor plate has conservatively been taken as a 1000mm width section and not assessed as 2 way spanning. I have attached a sketch I hope gives a better idea of what I am looking at...
Hi All,
An existing structural steelwork floor has an 8mm thick mild steel floor plate bolted on top of the structural steel beams. The existing calculations under loading fails when the plate is taken as simply supported and so was assess as fixed where the check was O.K. I am unsure on how I...
