A simple analytical model is presented to predict the ultimate punching shear strength of slab–column connections. The model is based on the physical behavior of the connections under load, and is therefore applicable to both lightweight and normal weight concrete. The model assumes that punching ...
Punching shear strength of interior slab–column connections strengthened with carbon fiber reinforced polymer sheets In this paper, punching shear strengthening of flat slabs using Carbon Fiber Reinforced Polymer (CFRP) sheets is studied. Fifteen specimens of reinforced c... MR Esfahani,MR Kianoush,AR...
Compared to conventional reinforced concrete (RC) flat-plate systems, post-tensioned (PT) flat-plate systems lack experimental studies on shear strength, and there are no studies that have been analyzed and collected with clear criteria (for example, calculation of effective depth, unbalanced moment...

5) punching shear strength 受冲切承载力 1. So the checking calculation for punching shear strength of the slab foundation is largely simplified,and the workload of the designers is reduced. 为了使平板式筏基受冲切承载力验算公式简化,便于工程设计人员的理解与使用,在已有研究成果的基础上,提出了...
It was found that the joint had sufficient shear strength against earthquake loading by installing top and bottom reinforcement in the slab and then extending the reinforcing bars into the wall module. With polytetrafluoroethylene sheets inserted, it was confirmed that the joint had greater...
