国外蒸压加气混凝土板式承重墙研究现状

Research Status in Autoclaved Aerated Concrete Load Bearing Panel Walls Abroad

与蒸压加气混凝土砌块墙相比,蒸压加气混凝土配筋墙板对低层建筑可不设置构造柱,混凝土现场浇筑量小、构件尺寸大的特点使其组装更高效。本文介绍了蒸压加气混凝土板式承重墙结构在国外的应用情况,结合已有研究成果和相关技术规范对该结构的力学性能进行了说明,并展望了该结构体系的应用前景。研究表明:蒸压加气混凝土板式承重墙的抗震性能良好,结构在设防烈度下可以保持预屈服状态,在大震作用下具有充分的强度储备。

Compared with autoclaved aerated concrete block wall,autoclaved aerated concrete panel wall of low-rise buildings has no need to composite with constructional column.Small quantity of concrete pouring and large component size make its assembly more efficient.The application of autoclaved aerated concrete load bearing panel wall structure abroad is introduced,and the mechanical properties of the structure according to the research results and relevant design codes are reviewed.Researches indicate that autoclaved aerated concrete load bearing panel wall has good seismic performance.The wall behaves in its pre-yield region under the seismic fortification intensity,and has sufficient strength reservation in strong earthquake.In conclusion,the application of autoclaved aerated concrete load bearing panel wall structure is prospected.
