PROBLEM TO BE SOLVED: To provide a rigid-framed structure that facilitates design work, enables construction work without being restricted by detailed construction plan, and realizes enhancement of flexural capacity of a beam, cost stabilization and cost reduction at a same time.SOLUTION: A rigid-framed structure 1 includes: a PCa column-beam member 12 prestressed by a PC steel member 37 extending in an X-direction, the column-beam member having a joint part 7 of a column 2 formed integrally with a half beam part 9 of an X-direction beam 3 connected to the joint part 7; and a PCa beam member 13 prestressed by a PC steel member 47 extending in a Y-direction, the beam member forming a Y-direction beam 5 separately from the joint part 7 of the column 2. The beam member 13 has a pair of widened beam parts 42 that widens the beam member laterally on both sides, at both end parts of a beam body 41 in an axial direction. The beam member 13 and the column-beam member 12 are pressure-joined with a PC steel bar 51 installed to pierce through the widened beam part 42 and the joint part 7, and a fastening metal fitting 52 that supports reactive force with an edge surface 42a of the widened beam part 42 opposite the column-beam member 12 side.SELECTED DRAWING: Figure 2 【課題】設計を容易とし、詳細な施工計画に縛られることなく施工可能とし、梁の曲げ耐力の向上とコストの安定化及び低廉化とを両立させる。【解決手段】ラーメン構造体１が、柱２の仕口部７と仕口部７に接合されるＸ方向梁３の梁半部９とを一体に構成し、Ｘ方向に延在するＰＣ鋼材３７によりプレストレスが導入されたＰＣａ製の柱梁部材１２と、柱２の仕口部７と別体に形成されてＹ方向梁５を構成し、Ｙ方向に延在するＰＣ鋼材４７によりプレストレスが導入されたＰＣａ製の梁部材１３とを有するものとし、梁部材１３が梁本体部４１の軸方向両端において両側方に拡幅する一対の梁拡幅部４２を有するものとし、梁拡幅部４２及び仕口部７を貫通するように設けたＰＣ鋼棒５１と、梁拡幅部４２の柱梁部材１２側と相反する側の端面４２ａに反力をとる定着金物５２とにより梁部材１３と柱梁部材１２とを圧着する。【選択図】図２
