[摘要] 以理论分析和工程实例分析为重点，分析预应力张拉后对钢筋混凝土梁受力特点，结合后张有粘结预应力混凝土梁正截面承载力计算方法，得出预应力钢筋张拉后的预应力钢筋混凝土梁承载力计算方法，将理论方法与实际工程结合，对阜新规划博物馆后张有粘结预应力钢筋混凝土梁进行承载力计算分析，选取一后张有粘结预应力钢筋混凝土梁进行正截面承载力计算，根据施工方及设计单位提供的数据，计算预应力混凝土梁的承载力是否满足要求，达到检验在建建筑构件是否安全目的。[关键词] 预应力; 大跨度; 承载力中图分类号：TU378.2 文献标识码：A 文章编号：1002-848X(2013)S2-0521-03*中国新兴建设开发总公司科技研发项目（ZXJZ20130501）。作者简介：刘海卿，教授，博导，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.
