摘要：
Multi-ribbed wall structure (MRWs) is composed of densely distributed ribbed frames, including ribbed beams and columns, and autoclaved aerated concrete (AAC) is filled inside the ribbed frames. Because of the special production process, there is a bonded interface of which property is still undefined between ribbed frames and infilled AAC. To study the properties of bonded interface of ordinary concrete and AAC, the experimental study is necessary on the material level. On the background of multi-ribbed composite wall structure, the slant shear test was used to measure the bonded interface properties of ordinary concrete and AAC. This paper analyzed the influence of bonded interface joint angle to interfacial strength and proposed the failure envelope of bonded interface. Based on test results, the equation between τn and σn of the bond failure envelope is fitted which provides a valuable basis of theoretical and numerical solutions for mechanical properties of multi-ribbed composite wall structures. © 2017, Editorial Board of Journal of Harbin Institute of Technology.
