Punching Strength of Reinforced Concrete Footings
by Josef Hegger, Marcus Ricker, and Alaa G. Sherif
A total of 17 reinforced concrete footings were tested to investigate
the punching shear behavior of footings. The test parameters
investigated are the shear span-depth ratio (a/d), concrete
strength, and punching shear reinforcement. The (a/d) ranged
between 1.25 and 2.0, whereas the concrete strength ranged
between 20 and 40 MPa (2.9 and 5.8 ksi). To study the effect of
soil-structure interaction, five footings were realistically supported
on sand. The remaining specimens were supported on a column
stub and a uniform surface load was applied. The present experimental
investigations indicated that the angle of the failure shear crack is
steeper in punching tests on compact footings than observed in
tests on more slender slabs. Furthermore, the (a/d) significantly
affects the punching shear capacity. Based on the test results, the ACI
and Eurocode 2 provisions are critically reviewed and improvements
are proposed.

感谢专家的分享
不知梁板式筏板基础梁是否需要演算框架柱对其产生的抗冲切呢?
尤其是BS中的冲切计算周长与GB比较,哪个更为合理啊?
