EFFECT OF COLUMN-TO-BEAM STRENGTH RATIO ON MAXIMUM STORY DRIFT ANGLE RESPONSE OF STEEL FRAMES SUBJECTED TO HORIZONTAL BIDIRECTIONAL GROUND MOTION
In this research, the authors investigate the effect of the column-to-beam strength ratio on the seismic response of 3D frames. Analyses were carried out by using bidirectional ground motion transformed into the directions of strong and weak axes. The maximum value concerning all the stories of the maximum story drift angle caused in an arbitrary direction when bidirectional ground motion was inputted along all the directions can be almost approximated by the maximum value among the responses when only the strong-axis ground motion was inputted along the direction of the structural plane and the response when only the strong-axis ground motion was inputted along the direction of 45° from the structural plane, in the range where the column-to-beam strength ratio is greater thaa √-2
