The influence of the number of rib columns on the Compressive strength of multi-rib composite wall

Based on the mechanical characteristics of Multi-ribbed composite wallboard, the computing model of different number rib column are established by ANSYS command flow segmented modeling methods. The model are progressively applied vertical load, horizontal and vertical interaction load, then the stress, strain and displacement of structure under the corresponding loads were calculated. Further analysis on the mechanical properties that affect of rib column number to multi-ribbed composite wallboard. Calculated the stress of multi-ribbed composite wallboard under different rib columns number, and analyze its working mechanism. Combined with displacement, stress and strain rule can be found: With the increase number of the rib column, displacement, stress and strain of structural model are gradually decreasing trend. And with the impact of rib columns number on the average size of ribs is gradually reduced. The displacement, stress and strain decreasing trend gradually slowing down. Combined with the actual construction environment and economic considerations can provide theoretical support for the rib column design of the real case structure.
