Abstract:

Investigations on the punching behaviour of eccentrically loaded footings

The design concept for punching shear according to DIN EN 1992-1-1+NA(D) has been derived from the results of tests conducted on centrically loaded footings. While a uniform distribution of shear stress along the critical perimeter is assumed for determining the punching shear resistance, load eccentricities are taken into account by the load-increasing factor &bgr;.
Theoretical and experimental investigations on the punching shear behaviour of eccentrically loaded footings indicate a reduction of the multi-axial stress state along the column face with increasing load eccentricity. Based on punching tests on eccentrically loaded footings described in literature, non-linear finite-element simulations have been performed and subsequently the influence of load eccentricity on the punching shear behaviour has been examined in parameter studies. Based on the results of the numerical simulations, an approach for the consideration of load eccentricities in the punching shear design of footings according to DIN EN 1992-1-1+NA(D) has been developed. This article presents and describes the results of experimental and theoretical investigations on eccentrically loaded footings and compares the new proposal with existing approaches by means of a systematic test series.
