Abstract:
In order to reduce the impact of cracks on the bearing capacity and durability of concrete structures, slotted concrete sandwich panels were proposed. The effects of slot depth and position on the cracking behavior of sandwich panels during lifting and normal use were studied. A finite element model was established using ABAQUS and its reliability was verified. Based on this, parametric analysis was conducted using slot depth and position as variables. Finally, the simulation results were compared and verified using theoretical formulas. The results show that on the premise of effectively controlling the location of cracks, reasonable slotting of the bottom of sandwich panel will not cause cracks to occur during lifting process. Under the condition of simple support at both ends, the slotted structure mainly affects the cracking load of sandwich panel, and has a relatively small impact on the ultimate load. In the early stage of crack development, by setting appropriate slot depth and position, the stress concentration effect can cause the tensile stress of sandwich panel to reach a large value in the slot and its vicinity, thereby achieving the effect of controlling the location of crack generation. As the depth and number of slot increase, the location of cracks is effectively controlled, but it will lead to a decrease in the cracking load of sandwich panel.
