Hollow Core Slabs system is a preferred solution for long spans, short
buildings, car parks, etc. Also, it is suitable for fast construction But, some
issues are considered common while erecting the Hollow Core Slabs or to be
obvious, when it comes to measuring the lengths from the drawings and the beams
widths are not drawn to scale resulting to shorter or longer spans and
eventually the panels will be delivered to the site with unexpected lengths.
This will lead to either cut the edges of the panels or part of the beams from
both ends of the panel which considered unacceptable in some cases or need to be
verified for the new dimensions!The below details show some suggestions to solve
the issue by increasing the shear capacity of the concrete at the ends of the
panels.
