| With the issue of series of policies such as wall-reform policy, energy-saving policy,protecting plantation, waste utilization and so on, clay products, especially clay brick,will be gradually forbidden to utilize in the most areas of our country, it is necessaryto select a new type of building material that can replace them. At the same time,product technique of autoclaved aerated concrete (AAC) is remarkably improved anda variety of products are developed, which objectively promote the application ofAAC products.In our country and other European countries, AAC block is usually applied in framestructures as infill panel and some public buildings。A few attempts of application inbearing structures are made according to some relative specifications and codes areavailable, however, in order to roundly replace clay brick some regulations must beurgently modified to gear to the development of all aspects.Based on the background mentioned above, this paper primarily complete study ofseveral aspects including vertical bearing capacity and horizontal aseismaticperformance of walls, in view of different bearing systems, cross walls andlongitudinal walls are considered simultaneously. In analysis, FEM analysis andrelative experiments of walls, combined with verification of an actual engineeringexample, are separately conducted and compared. As a result of the research, effectivestructural measures are adopted to form a reasonable aseismatic system of multi-storybuildings, which is found to be able to meet requirements of aseismatic design incodes, AAC block may become a good substitute for clay brick.AAC block bearing system has significant economic benefit and social benefit, inorder to extensively apply it to actual engineering, more experimental research mustbe carried out and more experimental units are needed. |
