Based on the stiffness limitations of the midtower in multitower cable-stayed bridges, a new stiffening system (tie-down cables) is proposed in this paper. The sag effects and wind-induced responses can be reduced with the proposed system because tie-down cables are short and aesthetic compared with traditional stiffening cables. The results show that the stiffening effect of tie-down cables is better than that of traditional stiffening cables in controlling the displacement and internal force of the bridge based on a static experiment and finite element analysis. Therefore, the proposed system can greatly improve the overall stiffness of a bridge, and its stiffening effect is better than that of traditional stiffening cables in controlling the displacement and internal force. The results provide a reference for the application of such systems in practical engineering.

Finite element analysis have been carried out in order to study the mechanical properties of the joints between elevated columns and truss column in substation frame. Firstly, the numerical results and the experimental ones were compared to verify the efficiency of the FEM model. Then, the whole process of elastic-plastic analysis was carried out to the prototype structure. The results show that when the bottom of the elevated column was yielding, the stress of the stiffeners at the joint is small, which can meet the design principle of “strong joint - weak member” criterion. Furthermore, when the structure enters into the elastic-plastic stage, the stress in the upper stiffeners at the horizontal load direction is large and most of them yield, but the stress in the plane gusset plate of the joint is still small.

The use of concrete-filled steel tubes in different areas of construction is becoming an attractive solution because of its remarkable performance. It provides not only an increase in the load carrying capacity but also good seismic behaviour. It is often adopted as compression member especially for structure under large axial pressure. Concrete-filled steel tubular composite truss can be used as main load-bearing structure of long-span and mega structure. But the composite trusses were connected by mutually intersecting joints which the welding construction process is complicated and the quality is unstable. Therefore, gusset plate joints are more suitable. So experimental study and finite element analysis are carried out in 12 specimens. Test results indicate that bearing capacity of hollow circular steel tube joints filled with concrete is provided obviously, and local buckling performance of steel tube under gusset plate is also improved. In order to study the mechanical performance and interaction of steel tube and core concrete, the ANSYS program is adopted in finite element analysis. And the analysis results is agreed well with the test. Regression analysis is carried out at the same time, thus simplified calculated formula of this type joints is concluded which can give reference for the designers.

There is wide use of beam-column joint with gusset plate angle connection in engineering, however, the mechanical properties of these joints are still lack of complete theoretical and experimental research. This kind of joint is often simplified as an articulated connection or other types of connections in the design. In this paper, experimental study and finite element analysis are carried out to study the flexural behavior of the beam-column joint with gusset plate angle connection. The finite element analysis is used to analyze the differences between the beam-column joint with gusset plate and other joints. The moments-rotation curves and failure modes of the three kinds of beam-column joints were obtained by the static test which were carried out. A more reasonable design of beam-column joint with angle plate of gusset plate is put forward through the research of this paper: the deformation of the column flange is restricted after adding the stiffener, which can avoid the premature yield of the column flange and making the joint have good energy dissipation capacity.

The present paper suggests an on-line hybrid test environment for evaluating the seismic performance of steel bracing connections. The test method combines substructuring techniques and finite element analysis. The behavior of the brace member is simulated by the finite element analysis program ABAQUS, while the bracing end connections are physically tested. Two actuators are used to simulate the physical continuity between the analytical and experimental substructures by controlling axial load and out-of-plane rotation. A MATLAB user subroutine is created as the interface between the main control program and ABAQUS to impose the target rotation and axial force to the connection quasi-statically. A gusset plate connection designed to behave as a pin connection is tested and its efficiency to accommodate inelastic rotations up to a 4.0% story drift is evaluated. The test method is reasonable and smooth operation is achieved. The test system ensures pragmatic loading and boundary conditions to the brace connections, which are tested in full interaction with the brace member until failure. The maximum strength and rotation capacity of the connection can be clarified under actual cyclic inelastic rotations and varying axial loads derived from the inelastic behavior of the brace member.
