Hi People,
Wondering what your thoughts are on post fixing punching shear reinforcement with an anchorage only on one surface.
Typically we would post install a bolt with washers top and bottom mimicking the reinforced bar equivalent to enhance punching shear on an existing slab.
Recently a...
Hi, I'm looking at designing a RC raft slab in a basement with thickenings under the columns. The basement slab is below the water table.
I'm thinking of designing the raft as two separate models. One as a suspended slab subjected to the uplift pressure in the negative gravity direction and one...
In designing a simply supported beam a scenario has arisen where there is a requirement to anchor 2 layers of bottom reinforcement at a column support with L bars, see attached sketch. It is probably similar to a situation which would arise on a deep beam close to a support, anchoring the...
I am investigating the possibility of post tensioning a 200 slab with quite a small footprint. The building is quite tall and a thin slab is very desirable for foundation loadings etc. The spans are roughly 10m square and each bay is continually supported at each edge i.e. the slab is...
BS 8110 (Clause 3.4.5.5) in referring to spacing of shear links states:
"At right angles to the span, the horizontal spacing should be such that no longitudinal tension bar is more than 150mm from a vertical leg; this spacing in any case should not exceed d"
Eurocode makes similar...
