New Reinforcement Model High Strength Concrete Columns To Force Performance

By changing the parameters of stirrups ratio and axial load ratio, 6 High Strength Concrete (HSC) columns are tested subjected to cyclic lateral load. The baring capacity of HSC columns with new form of stirrups are compared with HSC columns with normal form of stirrups. Load-Displace relation curves are obtained. Based on the test results, the failure mechanism, the factors affecting the strength and ductility of these columns are analyzed.A Fortran program is compiled to calculate the load-displacement skeleton curve. A storing force model is used to simulate the load-displacement curves. The calculating results are in good agreement with the experiment results.An artificial neutral network (ANN) program is compiled to analyze an experiment result of HSC columns subjected to axial load.
