| 摘 要： | 采用有限元法对陶粒钢筋混凝土梁进行非线性分析,是对有限的试验研究的有效补充和进一步深入探讨。根据陶粒混凝土梁的试验结果,建立了合理的三维有限元模型,对陶粒混凝土梁的抗弯性能进行了非线性有限元分析。计算得到的开裂载荷、极限载荷和载荷-挠度曲线与试验吻合较好,可以有效地模拟陶粒混凝土梁的抗弯性能。基于已建模型,可通过改变材料种类、配筋率、陶粒混凝土强度和钢筋屈服强度等参数,以进一步研究陶粒混凝土梁的抗弯性能规律。

| Abstract: | Adopting the finite element method to analyze the ceramsite reinforced concrete beam was the further study and effective supplement to the limited tests. Based on experimental results of ceramsite concrete beam ,a 3-D finite element model was established and nonlinear finite element method was used to analyze the flexural ceramsite concrete beam.The numerical results of crack load, ultimate load and load-deflection curve showed good agreement with the experimental results.This indicates that nonlinear finit... |
