Steel Trusses

Two 1/6 scale core walls, including one RC core wall with steel tube-reinforced concrete columns and concealed steel trusses and one conventional RC core wall, were tested under eccentric horizontal cyclic loading. The load-capacity, ductility, hysteresis characteristics, stiffness, stiffness deterioration process, energy dissipation and damage characteristics of the two specimens were compared and discussed in this paper. It shows that the seismic performance of the RC core walls under combined action could be improved by setting the concealed steel trusses in the walls and using the steel tube-reinforced concrete columns as the boundary elements.

In Fire

In this paper, temperature field analysis of concrete filled steel tube reinforced concrete columns in fire has been carried on. A finite element model for concrete filled steel tube reinforced concrete columns in fire is developed by ABAQUS. The cross-sectional temperature field distribution regularity of concrete filled steel tube reinforced concrete columns in fire has been obtained. Parameter analysis such as fire duration time and steel ratio on the column section temperature field is conducted, and this provide the reference for the further analysis of concrete filled steel tube reinforced concrete columns.
