通过 DM2型模数多孔砖砌体的通缝抗剪和轴心抗压强度试验与普通砖砌体通缝抗剪强度对比试验 ,对 DM2型多孔砖砌体的破坏机理、通缝抗剪强度、抗压强度、弹性模量、泊松比等力学性能进行了研究 ,得出了 DM2型模数多孔砖砌体采用现行规范中的计算指标是安全可靠的。并给出了 DM2型多孔砖砌体的弹性模量和泊松比建议公式。

Through the test of the stack shear strength and axial compression strength of DM2 modular cellular brick masonry and a contrasting test of the stack shear strength of ordinary brick masonry, as well as a research into the test of the failure mechanism, stack shear strength, compression strength, elastic modulus, and Poisson's ratio of DM2 modular cellular brick masonry, the author draws the conclusion that with the application of the present technical calculation index, DM2 modular cellular brick masonry is safe and reliable. The paper has further provided a formula for the elastic modulus and Poisson's ratio for DM2 modular cellular brick masonry. The paper aims at providing scientific support for the development of the industrial application of cellular bricks and the setting up of relevant design standard.
