Research On The Mechanical Behavior Of Embedded Type SRC Column Base

Steel Reinforced Concrete (SRC) structure which has the advantages of steel structure and reinforced concrete structure concurrently is a kind of structural with very good development prospect. Since relevant rules are issued, SRC structure gets faster development in our country. The column base connection, as a connecting link in structure, plays a very vital role and the study on its performance is very important.If the buried depth of embedded type column base is large enough, the shear andmoment on the column can be balanced by concrete's lateral pressure. So the foundations lab and anchor bolts should not be calculated. The method to calculate the depth now isthe same as steel column base's calculating method, which only considered concretelateral pressure nearby the web part of flanges to resist bending moment and shearingforce. However SRC structure is different from steel structure. Section steel has thereinforced concrete in the section intension, the flexure question can be neglected, therefore calculating the depth of SRC column base with the formula of steel structure isconservative and the calculating result is larger than the test result. This paper analysisthe results modle, load transfer by mechanism and the computational method of shearing resistance of embedded type SRC column base were presented, new means and method of computational theory and analysis were provided to intensity, rigidity, deformation and the development of crack of embedded depth and the effetive width of the SRC column base.
