(Yasushi NISHIMURA and Kohei HORIE, J. Struct. Constr. Eng., AIJ, Vol.76, No.666, 1523-1531, Aug., 2011)

Abstract

The above mentioned paper deals with the ultimate strength of beam-column joint panel consist of two-directional H-shaped steel beams and R/C interior column, based on the additional theorem.
The discusser's arguments are as follows;
1) The equations (4), (31) and (35) must be incorrect according to the discusser's understanding.
2) In proposed simplified prediction method, the condition on an amount of longitudinal reinforcement of column and axial force subject to column by which the prediction method is applicable should be specified.
