摘要
应用虚拟裂缝模型分析了混凝土保护层锈胀开裂的锈胀力。首先,考虑了混凝土和钢筋的实际变形情况利用断裂力学和弹性力学得到了混凝土保护层开裂时钢筋的最大膨胀力理论预测模型。然后通过与文献中的试验数据比较,验证了本研究数值方法的有效性。
Improved 2 000 kN automatic compressive machine is adopted to test the quasi-static mechanical properties of foam concrete under the condition of different water cement ratio and porosity.The law that the quasi-static compressive strength changes with water cement ratio and porosity and the rule that porosity affects the strain range are obtained.And the energy absorption property of foam concrete is also discussed.
