装配式再生混凝土砌块砌体力学性能试验研究与数值模拟
|
摘要
在12个装配式再生混凝土砌块灌芯砌体和9片灌芯墙体的试验研究背景下,基于有限元软件ABAQUS进行数值模拟。结果表明,灌芯砌体的基本力学性能数值模拟得到的砌块砌体应力-应变曲线可以直接运用于灌芯墙体建模中,提高了复杂墙体建模效率。数值模拟结果与试验结果吻合良好,ABAQUS能够有效分析装配式再生混凝土砌块灌芯砌体的抗压强度和弹性模量及灌芯墙体的抗压承载力等基本力学性能。
Under the experimental study background of twelve block masonry specimens and nine grouted-walls, numerical simulation is carried out based on finite element software ABAQUS. The results showed that the stress-strain curve of block masonry by numerical simulation can be directly applied to the modeling of grouted-walls, so the efficiency of the modeling of the complex wall is improved. The numerical simulation results are in good agreement with the test results, and ABAQUS can analyze the basic mechanical properties of the reinforced concrete block masonry effectively, such as compression strength, elastic modulus and compression bearing capacity.
