Abstract

Abstract

To solve the problems of difficult installation and positioning, and slow construction speed of prefabricated shear walls, a new type of prefabricated shear wall structure combining alveolar and U-shaped ferrule connections was proposed. The corresponding shear bearing capacity calculation model was preliminarily proposed by analyzing the shear-resisting mechanism of the horizontal joint of the structure. Then, based on the verification of the effectiveness of the finite element modelling method, the shear properties of the new type of prefabricated shear wall were analyzed. The analysis results showed that the new prefabricated shear wall structure exhibited a good mechanical properties, and its shear capacity was slightly higher than that of cast-in-place shear wall. For the shear properties of the new type of prefabricated shear wall with alveolar-type connections, the alveolar and the hidden beam played a major role in shear resistance. With the increase of the strength of the cast-in-place concrete, its shear properties improved significantly. However, the change of the alveolar aspect ratio and the height of the concealed beam had little influence on it. Finally, the theoretically calculated and finite element analysis values of the shear capacity of the new type of prefabricated shear wall with alveolar-type connections were compared. It was found that they matched well, and the maximum relative error was less than 10%.
