Ecological Efficiency of Life Cycle of Concrete Fabricated Composite Slab in Earthquake Area

With the development of prefabricated buildings, the construction mode of buildings has changed greatly. Infilled wall is an important part of architecture. The traditional manual masonry method is not suitable for the construction of prefabricated buildings. Precast concrete infilled wall, as a form of infilled wall suitable for the construction of prefabricated buildings, came into being. Infilled wall has a great influence on the performance of frame structure. Compared with the traditional masonry infilled wall, the concrete infilled wall has greater stiffness, better integrity and stronger bearing capacity. Based on the existing research, this paper analyzes the influence of the height width ratio of the concrete infilled wall, the wall thickness, and the tie mode with the frame on the structural performance through the finite element software Atena. Combined with the results of practical engineering modal analysis, this paper evaluates the value method of natural vibration period of concrete frame infilled wall structure, and puts forward some suggestions for Chinese codes.
