Junction structure of prestressed concrete (PC) column and steel beam

A column-beam junction structure composed of a prestressed concrete (PC) column and a steel beam that are integrally jointed to each other, the steel beam including an H-section steel as a beam main body and a beam end block that is provided at an end of the H-section steel, the steel beam being disposed in a state in which the end is mounted on a cogging provided to a side surface of the column,

• the beam end block including an end plate and an anchor plate, the end plate being fixed at an end surface of the H-section steel in a direction substantially perpendicular to a longitudinal direction of the steel beam, the anchor plate being fixed to the H-section steel separately from the end plate, on a side opposite to the column, in the direction substantially perpendicular to the longitudinal direction of the steel beam,
• the end of the H-section steel including an upper part and a lower part, the upper part protruding toward the column more than the lower part and being mounted on the cogging,
• the end plate including an outer end plate and an inner end plate, the outer end plate being fixed at an end surface of the upper part of the H-section steel and facing the side surface of the column via a first joint, the inner end plate being fixed at an end surface of the lower part of the H-section steel and facing the cogging via a second joint,
• the beam end block having a height dimension larger than a height dimension of the H-section steel, the beam end block having a lower end that is disposed at substantially the same height as a lower end of a side surface of the cogging facing the lower part,
• the column and the beam end block being penetrated by a PC tendon, the PC tendon being tensioned and anchored to a surface on a side opposite to the column of the anchor plate to perform the integral jointing,
• wherein a space between the end plate and the anchor plate is filled with a filler material.
