Flexural performance of assembly integral floor structure voided with steel mesh boxes

Enhancing the ease of construction fillers and large-span floors their overall mechanical performance is critical for prefabricated hollow slabs in modular building structures. Therefore, we propose a novel assembly integral two-way floor structure (8.4 × 8.4 m) consisting permanent (BDF ribbed steel mesh box) three precast one-way hollow-core with I-shaped flexural sections to address above problem. This report evaluates overarching mechanism full-scale model proposed system under uniform vertical loads. The experiment supports that possesses high bi-directional bearing capacity achieves purpose turning into floor. deflection value cast-in-site concrete frame beam, as junction between cast-in-situ sections, 88% below damage limit GB/T 50152–2012. strain bottom rebars girder slab identical hidden girder. profile mid-span beam reveals noticeable membrane effect, strengthening bending resistance system. Additionally, original was modeled using ABAQUS study further. analysis plastic development history stress-strain distribution specimen upgrading strength has slight improvement on stiffness but could lessen its damage. While rationalizing configuration more cost-effective option. Based pseudo-plate method simulation results, internal force equations were also recommended preliminary design.
