Abstract

Abstract: The low cyclic loading tests on two steel frames infilled with recycled aggregate concrete hollow slat walls were conducted to investigate the seismic behavior of each specimen. Combined with the feasibility verification of finite element simulation， the effects of wall opening on the failure mode， ductility， bearing strength and stiffness of specimens were studied. The results show that the wall opening has no significant effect on the failure mode of specimen; however， the wall opening has a slightly negative effect on the ductility， bearing strength and stiffness of specimen， which can still meet the seismic requirements. Meanwhile， some improvement suggestions were put forward for the installation process and connection method of hollow slat wall. The results of finite element simulation were in good agreement with the actual test results， which verifies the feasibility of the structural system and provides a reference for its seismic design.

Key words: steel frame; recycled aggregate concrete; hollow slat wall; wall opening; seismic behavior; finite element simulation
