Practical Oblique Section Design Method of Multi-Ribbed Composite Wall

The multi-ribbed composite wall,with the characteristics of load bearing,energy saving,heat preservation and shield wall,is a new type of wall structure with good seismic resistance performance.Based on the experiments of eight 1/2-scaled models of the multi-ribbed composite wall under low-cycle lateral loading,the influential parameters of the height-width ratio,the axial load,the form of sash,etc.,were taken into account,and the calculating methods of the oblique section bearing capacity of the composite wall was studied.This study can offer reliable evidence for the design of the multi-ribbed composite wall.The results of experimental study indicate that the multi-ribbed composite wall has good seismic resistance performance,and the calculating formula of practical oblique section design of the multi-ribbed composite wall is established.The clculating results of the formula given in this paper are in accordance with experimental results.
