摘要
本文以无粘结部分预应力砼梁为分析对象,建立材料分析模式,用非线性有限元分析方法,编制分析程序,计算结果与试验值吻合良好.通过对梁的抗弯、抗剪性能的影响因素的分析比较,提出相应实用计算公式.
In this paper,a nonlinear finite element methane developed to analyze and study the behaviors ofUnbonded Prestressed Concrete (U P.C)beam.The author adopts various material analysis models, makes a program by means of finite elementmethod to analyze U P.C test beams.The results of finite element analysis well agree with those oftest beams.By analyzing some factors which are considered to influence ultimate flexural strength andshear strength of U P.C beam,puts forward a practical calculation formula.
