Application of a new environmental protection building material in Steel Structural system

摘要

The cavity wall material is a kind of new saving energy and environmental protection building material having good physical and mechanic performance including lightweight, high strength, heat insulation and thermal insulation. Making full use of good physical and mechanic performance, as the infilling wall of steel frame structure, a new cavity composite masonry wall material is put forward, which can bear lateral load with steel frame together. Based on test of two specimens, the failure process and pattern is analyzed in detail in this paper, and the hysteretic behavior, energy dissipation and stiffness degeneration under the seismic force. Comparing with the steel frame, the cavity composite masonry infilling wall steel frame structure has higher strength, light weigh, higher stiffness, good anti-seismic behavior and ductility. The conclusion is reference for the seismic design of the infilling wall steel structure.
