The authors propose a method by which to infer the load −defotmatio ' n characteristics in the ultimato region of PC beams assembled by compressing to colu 皿 ns with round PC tendons . The conclusions are as described below . 1 ) Under the assumed appropriate deformation conditions , draw out of the PC tendo 皿 s 童 s computed on the basis of the bond characteristics of PC tendons , and a 皿 acro model which enables rotational deformations to be obtained is proposed , 2 ) the ana 亘 ys 正 s results
