[提要]  在大跨度无铰门式刚架的基础之上增设部分预应力水平拉杆，可有效地改善结构的受力，具有门式刚架和排架的特点。这种结构不但构件的截面尺寸减小，还省去了柱间和屋架支撑以及屋架的吊装费用，是一种值得推广的大跨度结构形式。

The new structural type of the framed bent of rigid joint, which improves the internal force by the PPC horizontal rod, is composed of the portal frame and the framed bent.  The rigid-joinl framed bent is worth popularizing, because its smaller sectional dimensiorl can reduce the cost of the bridging between columns, roof supports and the roof truss hoisting.
Keywords: PPC; rigid joint; monolithic space action; portal frame
