Getting this paper in there was a long process. From the first drafts in December 2010, via the first submission in May 2011 and then revised submission and finally acceptance and receiving the print proofs - it's been an adventure. First babysteps into the real academic life?
The abstract of the paper is the following:
One-way slabs under concentrated loads are generally designed for shear
by checking the beam shear resistance and the punching shear resistance
over an effective width. Only a small number of test data regarding the
shear resistance of one-way slabs subjected to concentrated loads is
currently available. To be able to better evaluate the shear resistance
of one-way slabs, a series of experiments was carried out on continuous
one-way slabs (5 m x 2.5 m x 0.3 m [16.4 ft x 8.2 ft x 11.8 in.])
subjected to concentrated loads close to the supports, in which the load
position, transverse reinforcement ratio, and concrete strength were
varied. The test results are compared with code provisions and a method
developed by Regan. The results show a different behavior in shear for
slabs under concentrated loads than for beams.
