Numerical Simulation of the out-of-plane mechanical properties of tall foam ceramic (FC) partition wall

Abstract

This paper conducts simulation research using Abaqus software and Finite Element Software on the out-of-plane mechanical properties of large-scale FC partition walls. Exploring the structural columns of 1.2m, 1.8m, and 3m, respectively, in large-size FC partition walls under out-of-plane loading, the cracking pattern of wall panels, the distribution of cracks, the damage pattern, the load-deflection curve, and the weak parts of the wall panels and the weak points of the wall panels under out-of-plane loading. The simulation results of experimental software in this paper show that the three specimens meet the design requirements, have good integrity before cracking, and are interoperable with steel bone and foam ceramic. Then, the finite element models of the steel frame-embedded foam ceramic wall with different densities were established, and the influence of the density of the foamed ceramic on the out-of-plane mechanical properties of the wall was further studied. The results show that when the density of foamed ceramics increases from 400kg/cm3 to 500kg/cm3, the fracture performance is significantly improved, while when the density increases from 400 kg/cm3 to 500 kg/cm3, the fracture performance is not significantly improved. It is also found that the out-of-plane bearing capacity of foamed ceramic walls with embedded steel frames increases with the increase of foamed ceramic density, and the mid-span deflection decreases with the increase of density. However, with the rise of embedded steel frame spacing, the influence of foam ceramic density on the out-of-plane load and mid-span deflection gradually diminishes. The results of this paper can provide some guiding significance for the design and construction of large-size and story-building partition walls in the future.
