Type: conference-paper
Abstract: To study the force-bearing performance of cast-in-situ concrete hollow floor slabs under vertical loads, a finite element analysis model of cast-in-situ concrete hollow floor slabs was established using ABAQUS software. The load-deflection curve, cross-sectional strain distribution, and concrete damage distribution characteristics of the hollow floor slabs under vertical loads were analyzed. The research results show that under vertical loads, the force-bearing process of hollow slabs can be divided into three stages: elastic, elasto-plastic, and yield; the strain distribution along the height of the rib beam section in the middle of the hollow slab conforms to the flat-section assumption; the damage to the concrete of the top slab of the hollow slab is mainly distributed at the four corners, while the damage to the concrete of the bottom slab is mainly distributed in the central area.
