Insight into the Effect of Adhesive Interface on the Ultimate Capacity of the Double‐Superposed Shear Wall

Abstract

is paper presents the results of a numerical and analytical study to investigate the effect of adhesive interface on the ultimate capacity of a new composite sandwich shear wall: double-superposed shear wall. e effect of adhesive interface on the ultimate capacity of two different wall configurations under different axial compression ratios was studied. e results indicate that, for the two different wall configurations, the bond strength of adhesive interface has a negligible effect on ultimate bearing capacity. As a result of the different intensity grades between cast-in-situ concrete wythe and precast concrete wythe, the double-superposed shear wall with precast boundary elements (wall configuration W3) yields a higher ultimate bearing capacity than that with castin-place boundary elements (wall configuration W2), when the axial compression ratio exceeds 0.2, which is contrary to the results under 0.1 axial compression ratio. A new calculation method for ultimate bearing capacity is proposed to take into account the different intensity grades, and the calculation results show a very good agreement with the numerical simulation results.

Experimental Study on the Seismic Performance of Insulated Single-Sided Composite Shear Walls under Different Shear Spans and Axial Compression Ratios

“…There are many studies on double-sided composite shear walls. Lian et al [12][13][14] studied the seismic performance of double-sided composite shear walls, while Wang et al [15,16] studied the seismic performance of composite shear walls with confined boundary members [17] and with openings; the seismic performance of the horizontal joints [16,[18][19][20] and the vertical joints [21] of composite shear walls, T-shaped walls [22], walls with a vertical seam [23], and connectors [24] are also the focus of Chinese researchers. There are few studies focused on the seismic behavior of single-sided composite shear walls.…”
