A few beautiful cruciform-section cast-iron columns on Clink Street in London:
The prison on Clink Street was burned down in 1780, and 1780-1800 sounds about right for cast iron to have been used in the construction of a warehouse or factory in London. A cruciform section is less efficient for column use than the more-common hollow-round or hollow-square sections – it has a smaller moment of inertia in every direction and therefore a smaller governing radius of gyration, which translates to a lower axial-load capacity when buckling governs or is a major factor – but these columns are so sculpturally pretty that I don’t care.
And yes, I am using the blog as a vehicle for vacation pictures. More to come.
