Electrochemical Mechanical Properties of Beam-Column Joints of Building Steel Structures under Impact Loads

To optimize the seismic performance in high-rise buildings, changes of beam-column joints steel structures buildings when they are impacted analyzed to obtain optimal choice joint combination. The most commonly used beam and column selected as research objects. Firstly, finite element model shell force established then combination six kinds is established. Secondly, applied data common impact actual collected, simulated this experiment according sampled data. Then, each under action external deeply explored through simulation. Finally, accuracy confirmed by calculation. experimental results comprehensively show that transmission mechanisms different for joints. Through calculation comparison, bending stiffness, strength, deformation, displacement degree joints, bearing analyzed. It concluded bolt-type diaphragm-type tube concrete steel-beam composite have better resistance than other five does not need be welded on site, on-site construction workers only assemble, which can reduce technical requirements workers, improving practicability applicability. Therefore, it shows reliable reference significance selection building structures.
