Dynamic performance of angle-steel concrete columns under low cyclic loading-II: parametric studyZheng Wenzhong and Ji Jing School of Civil Engineering, Harbin Institute of Technology, No.204 Haihe Road, Harbin 150090, China Abstract:
Tests of nine angle-steel concrete column (ASCC) specimens under low cyclic
loading are described in a companion paper (Zheng and Ji, 2008). In this paper,
the skeleton curves from the numerical simulation are presented, and show good
agreement with the test results. Furthermore, parametric studies are conducted
to explore the influence of factors such as the axial compression ratio, shear
steel plate ratio, steel ratio, prismatic concrete compression strength, yield
strength of angle steel and shear span ratio, etc., on the monotonic
load-displacement curves of the ASCCs. Based on a statistical analysis of the
calculated results, hysteretic models for load-displacement and moment-curvature
are proposed, which agree well with the test results. Finally, some suggestions
concerning the conformation of ASCCs are proposed, which could be useful in
engineering practice.
