ABSTRACT
With the development of modem construction the height and the span of building
are on the increasing the traditional structures of reinforced concrete can not meet
requirements of the modem construction. If reinforced concrete columns are still
applied in the high-rise building it will result in increased size of columns section
because of big pression and limits of pression ratio This not only
affects service function but also may e short columns whose seismic behavior is
poor .It is made known by a lot of experiments that steel reinforced concrete columns
can effectively reduce the pression ratio of column’s concrete part and
improve seismic behavior of the columns. As a result of steel staring a part of axial load,
So steel reinforced concrete columns specially steel high-strength reinforced concrete
columns are used in modem construction widely.
In this paper the main properties of different steel content SRC column joint under
cyclic loading are discussed based on the test result of four steel reinforced concrete
column reasonable steel contents is mended main include:
four steel high-strength reinforced concrete columns under the cyclic
reversed load The strain and displacement and load of every stage of test are gathered.
details of specimens the process of test and the main phenomena of th
