In the frame corners under opening bending moment there is a complex and non-linear distribution of stress. In such parts of structure the Bernoulli's principle is not fulfilled and the choice of a proper reinforcement is quite difficult. The authors of this paper suggest the use of Strut-and-Tie and FEM analysis as recommendable methods for the corners under opening bending moment.
In this paper a few typical reinforcement details are considered: reinforcement detail only with loop-shaped main bars, detail with one diagonal stirrup, detail with three parallel diagonal stirrups, detail with two fan-shaped stirrups and detail with three fan-shaped stirrups.
The other corner parameters are the same for all cases. The authors considered two different cases: section heights of column and beam are the same and section heights of column and beam are different, namely the beam is higher.
The first step of these analyses is to establish the required reinforcement using Strut-and-Tie method. The next step is FEM analysis performed in Abaqus software. In this step ULS and SLS are checked and yielding, history of load, cracking and non-linear behaviour of each corner detail are recreated. Thanks to corner efficiency factor, the most reasonable reinforcement detail is established.
