On the Nodes’ Anti-Crack and Load Bearing of SRHC Interior Joint with Different Axial Compression Ratios

Abstract:

By testing the seismic performance of the beams and columns of three SRHC with different axial compression ratios, the paper reveals the influence pattern of the nodes’ stress transfer and distribution, cracks’ appearance and development, member deformation, destruction pattern and mechanism, energy dissipation capacity etc., in SRHC with different axial compression ratios. The test shows that the increase of axial compression ratio postpones the appearance of the diagonal cracks in the nodes area, and slows down moderately the speed of development of the diagonal cracks, and improves the nodes’ energy dissipation capacity and ductility etc. this article studies its crack resistance and bearing capacity only. The purpose of this test is, through the low cyclic loading test of the nodes in the beams and columns of three SRHC with different axial compression ratios, to investigate the axial compression ratio’ influence on the cracks’ appearance, development, destruction pattern and deformation characteristics in the nodes; to analyze of the factors influencing the load-carrying capability; to validate the calculation methods proposed by related studies, which is little studied by foreign countries. This paper, based on the analysis of axial compression ratio test, further validates and improves the theory and methods proposed in the literature.
