It is very important for connection of between beam and column, connection safety and reliability is premise to guarantee the normal work of the whole structure. Node often bears complex stress which includes compression, bending and shear, so the study of the mechanical properties and ascertained behavior of mechanical, failure mechanism of between beam and column is very important. This paper use finite element analysis software to analyze the node of between SRC column and RC beam which exist in high-rise buildings but relatively few researches at present. Analyzed cracking load-displacement relation and studied on relation of concrete shear strain-section steel wing shear strain and crack load of joint core with different axial compression ratio, According to data of finite element analysis, this paper bring forward formula of crack resistance capacity of SRC column-RC beam joint core, At last compare theory value calculated with formula with test data, there being less error, it indicate the formula is reliable. |
