Abstract: Based on the experiment results of reinforced concrete structure spatial joints under oblique direction loading effect the working mechanism difference of the spatial joints with different section dimension and the seismic character under east-west, north-south and oblique direction loading effect has been studied. It can help structure engineers to master the seismic character of the structure subjected to the oblique direction earthquake effect.
