“…The JSCE-2002 code [6] assumes that the punching strength is proportional to the square root of the concrete compressive strength. It considers the effect of flexural reinforcement ratio and assumes that the critical perimeter is at 0.5d from the column faces.…”

The paper presents comparison between the punching shear calculations from six different codes and two equations from the literature. It utilizes 257 punching tests data collected from the literature. The concrete strengths, f'c, range between 12.3 MPa and 68 MPa, the reinforcement ratios range between 0.2% and 5.01%, and the slab depths range between 80 mm and 500 mm. It is found that the smallest error is for CEB-FIP-90 and EC2-2004 while the largest error is for JSCE-2002 and ACI318-19. Also, modifications to one of the equations of the Egyptian reinforced concrete code and two of the equations of ACI318-19 code for calculating the punching strength of flat plates without shear reinforcements are presented. The modified Egyptian and ACI318-19 codes equations for punching strength are compared to the experimental data and good correlations are noticed. The obtained errors are lesser than those of the original codes equations and the average errors are on the conservative side.

“…Their method is a uniform design method which is applicable for the cases of with or without punching reinforcement. Hamada et al [6] proposed a simple equation for calculating the punching strength of flat plates. Comparing the calculated punching strength using this equation to test data, a small average error is obtained.…”

“…The data about geometric characteristics, the number of tested footings, and supports used, are clearly arranged and presented in Table 1. Expressions from some regulations, based on the slab punching tests database, are analysed and evaluated in paper [28]. The regulations/standards analysed in this paper comprise ACI (1983), BS (1985), CEB-FIP (1990), prEN (1991), and two Japanese regulations.…”

Punching of column footings - comparison of experimental and calculation results

Punching of column footings-comparison of experimental and calculation results The column punching through the slab is most often related to floor structures, and less often to foundation slabs under columns. Calculation models for these two problems are often not separated. The deficit of experimental results for column footings results in the use of floor slab models. A review of the theoretical and experimental research references, including Codes/Regulations for punching calculation of column footings, is presented in the paper. The experimental research program and its implementation is described. The results obtained are compared with calculation results based on various regulations. Recommendations and directions for future research are outlined.

“…These test results provide reference for the development, verification and evaluation of punching shear design provisions. However, there are divergences among design provisions of various countries in aspects of location and shape of the critical section, calculation method of the nominal stress, value of the ultimate stress and other controlling factors [4][5][6].…”

A strength model was presented to give the mechanical explanation of the punching phenomenon, and to predict the punching shear strength of the interior reinforced concrete (RC) slab-column connection without shear reinforcement. The model assumes that the punching shear force is resisted mainly by the shearing-compression zone of a critical crack section, and the punching shear strength is determined as the minimum load among the loads which are obtained by the intersection of the demand curve and the capacity curve of each given flexure crack. The crack corresponding to the punching shear strength is defined as the critical crack. The capacity curve is obtained by the layer model of shearing-compression zone based on the biaxial strength theory of concrete. The demand curve is defined by equilibrium of forces in slab sector. For verification, the developed strength model was applied to existing test specimens tested by other researchers.
