摘要
传统混凝土挠度计算是先通过试验方法测量混凝土弹性模量, 再通过弹性模量求解挠度.在试验求解弹性模量过程中, 存在费力和难以全面检测等缺点.本文采用ABAQUS建立钢筋混凝土悬臂梁模型, 在不同载荷的作用下产生弯曲变形, 通过多组数值计算, 建立压力和挠度之间的关系方程.本研究可对相关工程提供指导.
The deflection calculation of traditional concrete is to measure the elastic modulus of concrete by testing method first, and then to calculate the deflection by elastic modulus. In the process of testing elastic modulus, the method has many shortcomings, such as laborious and difficult to detect comprehensive.ly. In this paper, a model of reinforced concrete cantilever beam was established by ABAQUS. The bend.ing deformation was produced under different loads. The equation of the relationship between pressure and deflection was established by many groups of numerical calculations. This study can provide guidance for re.lated projects.
