Abstract EN
Four full scale precast prestressed hollow-core slabs were tested under the influence of four lines loading with various values of shear span to effective depth ratio (a/d) (1.5, 2, 3.5 and 5).
The dimensions of the hollow-core slab were 2000 mm, 1200 mm and 150 mm (length, width and thickness, respectively).
All slabs were cast with a high compressive strength concrete of approximately 79.5 MPa.
Experimental test results showed four patterns of failure mode depending on the ratio of (a/d).
They were flexural failure, flexure-shear failure and shear compression failure.
In addition to combination failure between tension shear and anchorage failure, accompanied by sliding strand in concrete.
The failure loads decreased about 19.6% as (a/d) increased by 233.3%.
Finally, the highest first crack load, 110kN, was recorded for sample, HCS 1.5, having the lowest (a/d) ratio.
