3	12,993∼13,109	Plastic hinges appear at the top of column 1 and 2
4	13,342∼13,503	Plastic hinges develop at the bottom of column 4 and at the top and bottom of column 3
5	13,528∼13,552	Plastic hinge forms at the bottom of column 5 and then develops at the top of column 5
6	13,566∼13,743	Plastic hinge forms at the bottom of column 6 and then develops at the top of column 6
