（順德市順港建筑設計室 528300）[提要] 介紹28m跨部分預應力混凝土框架梁的設計，即預應力筋的布置、預應力損失計算、等效荷載計算、抗裂驗算、使用階段撓度驗算；同時將預應力筋張拉階段的張拉伸長值與理論值作了比較；對測試結(jié)果進行了對比分析。
[關鍵詞] 有粘結(jié)預應力混凝土 框架結(jié)構 設計 施工張拉 測試分析The design and testing of a 28 - meter span structure partially with prestressed reinforced concrete beams are introduced. It consists of the arrangement for prestressed bar, calculation of loss of prestressing force, prestressed equivalent loads, crack resistance and deflecti on in defferent using stage. The prestressing stage length of extension and test results are compared with the theoric calculation.
