Comparative Study on Loading Methods of Low Cycle Cyclic Loading Test for Reinforced Concrete Columns
摘要
Abstract
To investigate effects of loading methods on results of low cycle cyclic loading test for reinforced concrete columns, the current loading methods used in low cycle cyclic loading tests were compared and the influence of end constraint on test results of half-column specimens was analyzed.Low cycle cyclic loading tests were conducted on a full-column specimen and two half-column specimens with the same dimensions and reinforcement.One of the half columns was loaded by the traditional method in which the vertical load was applied on the top of the column through a sphere hinge, and the other was loaded with a well-designed pinhinge device.By comparing hysteretic loops, envelope curves, ultimate load and displacement, and accumulated dissipated energy of the half columns with those of the full column, it was found that the test results of the half-column specimen loaded with a pin-hinge device agree well with those of the full column,while the tested ultimate load of the other half column is 33％ larger than that of the full-column specimen due to the constraint at the top of the column.The pin-hinge loading device is therefore suggested to be used in low cycle cyclic loading test for half-column specimens.关键词
