Composite action on web-post buckling shear resistance of composite cellular beams with PCHCS and PCHCSCT

This paper aims to study the composite action on web-post buckling (WPB) resistance of cellular beams with precast hollow core slab (PCHCS) units and concrete topping (PCHCSCT). Geometrical material non-linear analyses are performed. A parametric is developed, varying opening diameter, width shear stud spacing, single double row. It was found that models row studs showed global greater than or equal only one For PCHCS, there a reduction in some due absence second opening, close support. PCHCSCT models, an increase resistance, comparison PCHCS models. However, most these rupture occurred. Finally, WPB were compared simplified equation takes into account buckling, Vierendeel bending. The average, standard deviation variation value ratio between analytical numerical 0.833, 12.47% 1.55%, respectively.
