This paper developed a finite element modelling (FEM) to simulate two frame specimens composed of steel reinforced concrete beam and angle-steel concrete column under horizontal loading. In the FEM, a series of simulation technologies such as defining material models, selecting element types, applying load, and parameters determination were described. Through the FEM, the skeleton curves, failure modes, and strain distribution are acquired, and the calculated results are basically agree well with the tests. Furthermore, the mechanism of the composite frame structure under horizontal loading is analyzed.

Based on the simulated results of joint of SRC beam and RC column (steel reinforced concrete beam and reinforced concrete column) with steel anchor, an analytical research on failure models and shear performance of three types of joints is conducted, which is composed of SRC beam and RC column, of SRC beam and column (steel reinforced concrete beam and column) and of SRC beam and ASC column (steel reinforced concrete beam and angle-steel concrete column). Then the parameters analysis for joint of SRC beam and ASC column is carried out, and the design formula of shear capacity for joint of SRC beam and ASC column is given on account of a great number of calculated and statistic results.

Load Tests

The low-cycle repeated load tests were conducted for two composite frames, with reinforced concrete column and steel reinforced concrete column, respectively. The performance of the composite frames such as the failure modes, ductility, energy dissipation ability, deformation restored ability, and resistant capacity is analyzed. Experimental results show that good seismic performance can be obtained by appropriate constructional measure which can meet the seismic design requirements. Based on the analysis of test data, the reliability of the beam-to-column connections is validated, and the seismic performance of composite frames is found to be influenced mainly by vertical anti-lateral force component. Besides, the form of steel reinforced concrete column is recommended to improve the structural ductility.

The paper presents the experimental studies of reinforced concrete column (RC column) capacity affected by core drilling. By testing three groups (9 total) of full scale concrete short columns, the experiment demonstrates that the axial compression capacity of RC columns after core drilling is reduced from 5.63% to 22.14% while the ultimate displacement decreases from 1.88% to 26.14%. The behavior of columns is altered from the axial compression failure to a small-eccentricity compression failure. The paper summarizes experiment results, followed by an investigation of the dominant factors, such as column effective cross section, drilling location, drilled hole repairing and reinforcing steels discontinued by drilling, that have impact on RC column capacity. The rationale of capacity variations of RC columns due to core drilling is also investigated.
