Experimental Study on Seismic Performance of Transversely Ribbed Corrugated Steel Plate–Steel Pipe Concrete Shear Wall

Abstract

To enhance the seismic resilience of building structures and refine the stability and longevity of buildings, it is essential to implement strategies that not only reinforce their structural integrity but also ensure their enduring functionality. The seismic performance test of corrugated steel plate–concrete–filled steel tube shear walls with transverse ribs was studied. Three specimens of shear walls featuring transversely ribbed corrugated steel plates filled with concrete were fabricated, namely, a C–shaped shear wall with four square steel tube concrete columns (specimen C40), a C–shaped shear wall with vertical loading beams (specimen C40X), and a C–shaped shear wall with two steel tube concrete columns (specimen C40LX). Each specimen was equipped with transverse–rib corrugated steel plates with the same parameters. The seismic performances of the specimens were tested by applying loads to different specimens through the displacement–controlled loading system. The tests show that the hysteretic curves of test piece C40 and test piece C40X are not full compared with that of test piece C40LX; the cracking load, yield load, peak load, and ultimate load of both are significantly lower than those of test piece C40LX; and the energy consumption levels of test piece C40 and test piece C40X are relatively weak. The test piece C40LX obviously has a high ductility coefficient, and the stiffness decrease under load is relatively small. During the loading process, the strain change law of the vertical reinforcement in the bottom section of the wall also maintains a reasonable state. It can be seen that the C–shaped transverse–rib corrugated steel plate–concrete–filled steel tube shear wall with two concrete–filled steel tube columns has a higher seismic performance.
