Flexural Strength and Stiffness of Donut-Type Voided Slab
The voided slab system has been known as an effective technique to replace a heavy reinforced concrete slab system without the decrease in flexural strength. However, according to the previous studies, the flexural capacities such as flexural strength, stiffness and ductility of the voided slabs were practically lower than that of the solid slabs depending on the void shapes and details. Therefore, in this study, an analytical and experimental study were conducted to derive the optimal voiddoi:10.3390/app12125782 fatcat:m2nbdqgaobdbneghecldsim54m
