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。为推广模数多孔砖的生产应用和制定其设计规范提供了科学依据
Through the comparison test between the through-seam shear strength and axial compressive strength of DM2 modular perforated brick masonry and the shear strength of the through-seam of common brick masonry, the failure mechanism of DM2 porous brick masonry, , Compressive strength, elastic modulus, Poisson’s ratio and other mechanical properties have been studied. It is concluded that the DM2 modular perforated brick masonry is safe and reliable by using the calculation indexes in current codes. The formula of elasticity modulus and Poisson ’s ratio of DM2 porous brick masonry are given. In order to promote the production and application of modular perforated brick and to develop its design specifications provides a scientific basis
