ANALYSIS OF MOMENT-ROTATION CURVE FOR SEMI-RIGID JOINT OF EXTENDED END PLATE CONNECTION

摘要

The traditional design of steel structure always simplify the joint as ideal rigid or hinged. However, joint is neither ideal rigid or hinged in the actual project, it is semi-rigid. After establishment finite element model of semi-rigid end plate, the static performance was analysed. Consider the end-plate thickness, bolt diameter, bolt spacing, beam height and column web stiffeners five factors, study the various factors effects on the end plate of semirigid joint capacity, deformation characteristics and moment-rotation curve characteristics.
