This paper introduces an innovative structure for a self-restrained grid shear wall with diagonal CFRP-steel composite strips. Steel and CFRP strips are interwoven to enhance the structural integrity of the shear wall. Quasi-static tests are initially conducted on two shear wall specimens with and without diagonal CFRP-steel composite strips. Subsequently, a finite element model is established to represent the self-restrained grid shear wall with diagonal CFRP-steel composite strips. This model is helpful for exploring the influence of composite strips arrangement on the performance of shear walls. Furthermore, a prediction formula is developed to estimate the load-bearing capacity of the CFRP-steel composite strips grid shear wall. The test results show that the yield bearing capacity, ultimate bearing capacity, stiffness and energy dissipation capacity of the specimens increase by 46.6%, 58.2%, 43.6%, and 16.3% respectively after the replacement of composite strips. In addition, the results of finite element simulation indicate that the diagonal arrangement exhibits the highest efficiency in the use of CFRP materials among three reinforced structural forms-diagonal, spaced, and fully arranged composite strips. This arrangement is also the most economical and has the least adverse influence on the internal forces of the frame columns. • Completely discrete steel slit shear wall into steel plate strips. • The steel and CFRP strips are interwoven to enhance the seismic performance of the shear wall. • The effects of different composite strip arrangements are investigated. • The prediction formula of the ultimate bearing capacity of the grid shear wall with CFRP-steel composite strips has been derived.

This paper introduces a novel aluminum honeycomb sandwich panel buckling-restrained steel plate shear wall (HCSP-SPSW) that used honeycomb core sandwich panels (HCSP) as restraining members. Compared with the traditional concrete restraining panel, HCSP is lighter, more rigid, and offers additional functions such as energy and sound absorption, increasing functionality while effectively restraining out-of-plane buckling deformation of the wall panel. Quasi-static cyclic loading tests were initially conducted on two 1/3 scaled specimens to study their shear performance. Second, a finite element (FE) model is established and validated, and parameters such as chunking and honeycomb core dimensions are analyzed. Furthermore, an equation for calculating the bearing capacity of HCSP is derived and confirmed through the finite element analysis. The results reveal that, when the out-of-face equivalent modulus of HCSP is 5945.51 MPa, HCSP-SPSW improves the load carrying capacity by 16.42% and increases energy consumption by 80.54% compared to the thin steel plate shear wall (SPSW), and achieves the requirement of complete buckling restrained behavior. The effect of partitioning on shear bearing capacity and energy dissipation is minimal when the number of bolts and edge spacing remains constant. [ABSTRACT FROM AUTHOR]
