The punching shear at the critical section was assumed to be mainly counteracted by the intact concrete in the compression zone of the footing. In the model, the effect of the friction force between the bottom surfaces of the footings and the soil was considered. The proposed model was ...
In the reinforced concrete column to footing connection design, the region around the column is exposed to punching shear failure. This is an undesirable failure since it results in a brittle failure and it governs the strength of the footing in column to footing connection. The shear stresses ...
In present analysis, ultimate bearing capacity of footings residing on sub soils comprising of two layers has been investigated for the event of a thin soil layer overlying a weak deposit. Pseudo-static approach has been applied to find out the ultimate bearing capacity of shallow strip footing ...
