While at a converted mill, the owner had me take a look at two unrelated areas both of which made me sweat and curse. One is a jack arch slab supporting an inhabited floor. The arches span between beams at 36" on center (presumed steel "S" beams) and are reinforced in the transverse direction...
I'm in a situation where I have been asked to verify that it is okay to remove an existing HSS6x6 from an existing building. I want a way to verify loading on it directly in the field, having run out of easy options for analysis, and am looking for suggestions.

I'm a civil engineer working on a project in Massachusetts.
Do seawalls need to be designed to meet the loading/overtopping/scouring conditions of a 100 year storm? Most certainly have not been (by inspection), and I have never before been asked to check the recurrence at which a wall will be...
I have been trying to check an uplift scenario for a finish-work installing client. In this case, they are trying to put terrace patio pavers on a high rooftop in a hurricane prone region. The IBC specifically says that aggregate is not allowed on roofs, and that ballasted roofs are not...
