There are numbers of methods have been proposed to evaluate the influence from opening on punching shear resistance in flat slabs in the vicinity of columns. In the present paper, the aims are going to compile this state of review on the evaluation of the predicted punching shear strength. A total of 79 tested slabs without shear reinforcement were selected from literature to study the treatments by these methods. The comparisons from t heir failure loads comparing to their reference specimens without opening shows that the punching s hear resistance is inversely proportional to the opening size, location and distance to the face of the related columns. The predictions by ACI-318 and EC2 are investigated to give unsafe punching sh ear resistance in most cases.
