To provide a rigid-frame structure which can be used irrespective of the size of a span, and can further reduce a material cost and a construction cost with a large span (80 m or more).SOLUTION: In a pentagon rigid-frame structure 1, lower diagonal beams 14 having relatively high gradients and upper diagonal beams 15 having relatively lower gradients extend in this order from a column head of supports 11 erected with a constant span and the upper diagonal beams 15 are made to abut on each other at an apex of a span center, and diagonal tension materials 12 are installed between the lower end and the column head at a position lower than the column head of a compressive material 13 suspended from the apex.SELECTED DRAWING: Figure 1
【課題】スパンの大小に関係なく利用でき、大スパン（80ｍ以上）で更に材料コストや施工コストを低減させるラーメン構造物を提供する。【解決手段】一定距離のスパンで立設した支柱11の柱頭から、相対的に高勾配の下斜梁14と相対的に低勾配の上斜梁15とを前記記載順に延ばして前記上斜梁15をスパン中央の頂点で突き合わせ、頂点から垂下した圧縮材13の柱頭より低い位置にある下端と柱頭との間に傾斜引張材12を架設してなる五角形ラーメン構造物１である。【選択図】図１
