    FRP Column Buckling

    This is not a reinforced concrete beam with fiberglass rebar. The full section is FRP. The question is that since Euler buckling is caused by a positive feedback loop involving increased bending, why the bending modulus isn't the specified modulus used in design. I have an inkling that for...

    FRP Column Buckling

    I'm analyzing a beam-column according to ASCE's Standard for Pultruded FRP Structures. The material has a flexural modulus of ~4,300 ksi and a compressive modulus of ~2,100 ksi. Given the mechanics of buckling (axial load + lateral deflection -> bending -> more deflection ->more bending) it...

    Net bearing pressure

    Is the net allowable bearing pressure in excess of what the previous in-situ stress was, or in excess or the adjacent pressure? For example, say I have a basement with a wall footing. The footing is 10' deep the basement floor is 8' deep. Am I calculating the net pressure in excess of...

    Curing concrete w/o lime water

    It's for QC. The water temperature has been 70-75 F the whole time so far.

    Curing concrete w/o lime water

    Hi, So I've got some samples that were cured in tap water without any lime added. It was noted that there was a film on top of the water after a couple days. I take it this was lime that leached out? How useful will the break data be?
