(重慶建筑大學 630045)[提要] 在大跨度無鉸門式剛架的基礎(chǔ)之上增設(shè)部分預應(yīng)力水平拉桿,可有效地改善結(jié)構(gòu)的受力,具有門式剛架和排架的特點。這種結(jié)構(gòu)不但構(gòu)件的截面尺寸減小,還省去了柱間和屋架支撐以及屋架的吊裝費用,是一種值得推廣的大跨度結(jié)構(gòu)形式。
[關(guān)鍵詞] 部分預應(yīng)力 水平拉桿 整體空間作用 門式剛架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.
