[摘要] 以理論分析和工程實例分析為重點，分析預(yù)應(yīng)力張拉后對鋼筋混凝土梁受力特點，結(jié)合后張有粘結(jié)預(yù)應(yīng)力混凝土梁正截面承載力計算方法，得出預(yù)應(yīng)力鋼筋張拉后的預(yù)應(yīng)力鋼筋混凝土梁承載力計算方法，將理論方法與實際工程結(jié)合，對阜新規(guī)劃博物館后張有粘結(jié)預(yù)應(yīng)力鋼筋混凝土梁進(jìn)行承載力計算分析，選取一后張有粘結(jié)預(yù)應(yīng)力鋼筋混凝土梁進(jìn)行正截面承載力計算，根據(jù)施工方及設(shè)計單位提供的數(shù)據(jù)，計算預(yù)應(yīng)力混凝土梁的承載力是否滿足要求，達(dá)到檢驗在建建筑構(gòu)件是否安全目的。[關(guān)鍵詞] 預(yù)應(yīng)力; 大跨度; 承載力中圖分類號：TU378.2 文獻(xiàn)標(biāo)識碼：A 文章編號：1002-848X(2013)S2-0521-03*中國新興建設(shè)開發(fā)總公司科技研發(fā)項目（ZXJZ20130501）。作者簡介：劉海卿，教授，博導(dǎo)，Email：lhq2008@163.com。Analysis on post-tensionging bond prestressed structural carrying capacity of Fuxin planning museumLiu Haiqing1, Wu Qiaoyi1, Li Dong1,Zhang Junfeng2(1 College of Civil Engineering and Architecture Liaoning Technical University, Liaoning, Fuxin 123000, China; 2 China Emerging Construction Development Corporation, Beijing 1000000, China)Abstract: Based on the analysis of the theoretical analysis and engineering examples. That analyzes the forced features of prestressed concrete which has been tensioned in the first place. Combined with the calculation formula of flexural bearing capacity of the post-tensioning bond prestress concrete beams to draw a conclusion that the calculation formula of flexural bearing capacity of prestressed concrete which has been tensioned. Then we analyze the flexural bearing capacity of the post-tensioning bond prestress concrete beams of Fuxin planning museum by combining theory with practical engineering and analyze the flexural bearing capacity of the post-tensioning bond prestress concrete beams which is selected from the practical engineering. According to the data provided by the contractor and design units, checking whether the bearing capacity of the concrete beams can meet the design requirement for achieving the purposes which make sure the components are safe.
