In high-rise wall-type residential buildings, thick RC transfer slabs have been widely used for parking space or public space. Despite the different behavior from thin RC flat slab, design methods for thin RC flat slab are applied to the thick RC transfer slab, due to the limited literature on the two-way shear behavior of RC transfer slab systems with small shear span-to-depth ratio. In the present study, concentric compression tests were performed on eight RC transfer slabs with small shear span-to-depth ratio to investigate the two-way shear strength. The test parameters were the concrete strength, shear span-to-depth ratio, slab thickness, and reinforcement ratio of the slab. The two-way shear strength, deformation capacity, failure mode, and strain distribution of slab rebars of the slab specimens were evaluated. The test results showed that the use of high-strength concrete or large reinforcement ratio increased the two-way shear strength of the transfer slab specimens. However, the transfer slab specimen having large slab thickness without sufficient reinforcement was susceptible to punching shear failure, showing insignificant strength increment. The two-way shear strengths of the test specimens were compared with the predictions of the current design method and the strut-tie model.

在高层壁式住宅中，厚厚的RC传递板已广泛用于停车位或公共空间。尽管与薄RC平板的行为不同，但由于对RC传递平板系统的双向剪切特性的影响较小，因此薄RC平板的设计方法仍适用于厚RC转移平板。深度比。在本研究中，对八个剪切跨度与深度之比小的RC传递板进行了同心压缩试验，以研究双向剪切强度。试验参数为混凝土强度，剪切跨度与深度之比，板厚和板的增强比。评估了板坯标本的双向剪切强度，变形能力，破坏模式和应变分布。试验结果表明，使用高强度混凝土或较大的配筋率可以提高传递平板试样的双向剪切强度。然而，具有大板厚而没有足够增强的转移板试样容易受到冲切剪切破坏，显示出微不足道的强度增加。将试样的双向剪切强度与当前设计方法和支撑杆模型的预测值进行了比较。
