Abstract: This paper
describes low cyclic loading testing of nine angle-steel concrete column (ASCC)
specimens. In the tests, the influence of the shear-span ratio, axial
compression ratio and shear steel plate ratio on the hysteretic behavior, energy
dissipation, strength degradation, stiffness degradation, skeleton curve and
ductility of the ASCCs is studied. Based on the test results, some conclusions
are presented. The P-¦¤ and sectional M-§¶ hysteretic
models for the ASCCs are presented in a companion paper (Zheng and Ji, 2008).
