EXPERIMENTAL STUDY ON SHEAR CAPACITY ON REINFORCED CONCRETE MEMBERS WITH WELDED STIRRUPS

Abstract

Abstract

Reversed cyclic loading tests were carried out on 6 reinforced concrete short columns with welded stirrups and 3 comparative reinforced concrete short columns with ordinary stirrups to study the shear properties of reinforced concrete members with welded stirrups． Also，the tests of 5 reinforced concrete beams with welded stirrups and 4 reinforced concrete beams with common stirrups were carried out to study the shear performance of inclined section． The influences of the factors such as the concrete strength，stirrup ratio，axial compression ratio and shear span ratio on the shear bearing capacity of reinforced concrete column and beam with welded stirrups were analyzed，and the differences of the shear bearing capacity between the welded stirrups and ordinary binding stirrups of reinforced concrete column and beam were compared． The results indicate that the damage form is basically the same， and the shear bearing capacity of reinforced concrete column and beam with welded stirrups are higher than the ordinary elements． In addition，the shearing bearing capacity is low，when using the formula in the currentCode of Concrete Structure Design( GB 500102010) ． Therefore，the test data were analysed and the calculation formula of shear bearing capacity for reinforced concrete column and beam with welded stirrups was fitted out in this paper． It is shown that the calculation values are in good agreement with the test results，which can be used for engineering design．
- welded stirrup,
- reinforced concrete,
- short frame column and beam,
- shear bearing capacity
