Analysis of the Mechanical Properties of a Bidirectional Laminated Slab with Shear Keys

The load-bearing capacity of a bidirectional laminated slab with shear keys arranged in rectangular grid (BCSWSK) was investigated to determine its mechanical properties, using load tests on fabricated and finite element models. force distribution across the measured analysed, effects different parameters were identified. interfaces between cast bottom strongly bonded, as interface precast cast-in-place upper slab, despite it being secondary concrete pouring. distributed similarly along X direction (columns) Y (rows) key arrangement. forces greater reached maximum value sooner, but differences columns mostly less than 10%. A square cross-section is recommended for keys. number rows, columns, cross-sectional area are main factors influencing properties composite they individually increased, point at which further increase had little effect. Similarly, after certain used, grade situ, grade, friction coefficient influence BCSWSK.
