SHEAR CAPACITY OF MULTI-RIBBED COMPOSITE WALL

摘要

The multi-ribbed slab structure is a new, light and energy-saving residential building structure with good seismic performance. As the main bearing member of the structural system,multi-ribbed composite wall often fails in shear under vertical and horizontal loads. Based on the results of previous study, the paper studies the shear capacity of the wall. To this end, the main factors,that influence the shear capacity of the wall are discussed, and, according to ultimate balance theory and experimental results, a shear formula which takes the main factors of shear capacity into account is proposed. In addition, a satisfactory agreement is obtained from the comparison between the values from the formula and experimental results. Theoretical research and test analysis show that the shear formula of the multi-ribbed composite wall is valuable for theoretical analysis and practical application.
