Abstract：Numerical simulation techniques were employed to construct stress-performance models for both prefabricated ex-panded clay aggregate concrete composite slabs and conventional concrete composite layers.Stress distribution under identical load-ing conditions was analyzed to reveal their stress mechanisms,with particular emphasis on changes of key parameters such as de-flection and ultimate bearing capacity.Under a 45 kN load,the deflection of the lightweight aggregate concrete composite slab was approximately 8 mm,while that of the ordinary concrete composite layer was 9.5 mm.The overall average ultimate bearing capacity of the lightweight aggregate slab was 312.5 kN,12.1％higher than that of the ordinary slab.Stress distribution was more uniform,with no significant concentration phenomena.In practical engineering applications,prefabricated expanded clay aggregate concrete composite slabs exhibit superior load-bearing performance and are suitable for engineering promotion.
