Steel-Concrete Composite Beams with Precast Hollow-Core Slabs: A Sustainable Solution

Industrialization of construction makes building operation more environmental friendly and sustainable. This change is necessary as it an industry that demands large consumption water energy, well being responsible for the disposal a high volume waste. However, transformation sector big challenge worldwide. It also known largest proportion material used in multistory buildings, thus its carbon impact, attributed to their slabs main contributor weight. Steel-Concrete composite beams with precast hollow-core (PCHCSs) were developed due technical economic benefits, owing strength concrete self-weight reduction, making this system economical lower footprint, reducing emissions. Significant research has been carried out on deep need overcome larger spans resist loads. The publication SCI P401, accordance Eurocode 4, however limited depths from 150 250 mm, or without topping. paper aims investigate topping understand effect flexural behavior beams, considering hollow-core-slab depth greater than P401 recommendation. Consequently, mm 265 units considered assess increase hollow core unit depth. A comprehensive computational parametric study was conducted by varying situ infill strength, transverse reinforcement rate, shear connector spacing, cross-section steel. Both full partial interaction models examined, some cases similar resistances obtained, meaning same can be obtained smaller number studs, i.e., less energy consumption, reduction embodied energy. calculation procedure, according 4 favor safety partial-interaction hypothesis.
