COMPUTATIONAL ANALYSIS FOR STEEL-PLATE SHEAR WALL BASED ON THE NODE CONNECTION CHARACTERISTICS

Based on the study of a new semi-rigid composite frame with a steel-plate shear wall system, the structural bearing capacity of different wall forms, the stress and deformation development history are analyze using ANSYS program, and the effects on the bearing capacity of a hinged connection, a rigid connection and a semi-rigid connection are compared. The results show that the yield limitation of the frame is increased about 20%, and the ultimate bearing capacity is increased about 10% after setting stiffeners. For a bending-frame steel-plate shear-wall structure, the beam and the column are combined through the rigid connection with wall to form a double lateral force resisting system, and the ultimate bearing capacity of a rigid node is increased about 15% than that of a hinged one. There is about 5% difference for the ultimate bearing capacity between a semi rigid node and a hinged one, which is only a single lateral force resisting system. The research provides a basis for the new structural system and its theoretical analysis.
