Abstract A steel–bamboo SI (skeleton–infill) system with steel frame as the skeleton and bamboo box as the filler is proposed, which realizes the requirements of building assembly and sustainable development. As a first step in studying the seismic behavior of the steel–bamboo SI (skeleton–infill) system, a simplified plane steel frame–bamboo infilled wall structure is tested under low-cycle reversed loading in this paper. The deformation mode, failure mode, hysteretic behavior and energy dissipation performance of the system are discussed. The test showed that the steel frame and the bamboo infilled wall were well connected and could work together. Then, the formulas for calculating the lateral stiffness of the system and the axial stiffness of the equivalent diagonal brace which replaced the infilled wall are obtained by theoretical analysis. The error between theoretical calculation and test results was about 1.3%, which proved the correctness of the proposed formula.

Nonlinear Behaviors

Considering the nonlinear behaviors of semi-rigid connections, a new calculation model for the second order elastic-plastic analysis of plane steel structures is presented by replacing the general element with a new one, which has two rotational springs at its ends. Based on the theory of beam-to-column, the element’s rotation-displacement equations are revised, and the second order elastic-plastic rigidity matrix of this kind of structure is derived in this paper. And the second order elastic-plastic program of this kind of structure is worked out. Two steel frames are calculated with this program. The results of calculations show that this model is reliable and fit to the analysis of all plane steel structures.

This paper representsexperimental and numerical study the behavior of the rubberized steel frame connections. One single-bay, one-story without elastic buckling are cyclically tested. The experimental specimens are simulated and analyzed by the ABAQUS program. Four specimens of steel plane portal frame are investigated under horizontal reversed cyclic loads. The specimen connections are developed by using different diameters of composite steel bolts/rubberinstead of conventional steel bolts to connect the beams with columns. The yield and ultimate strength, ductility, envelope curves, and damping ratio of these specimens are analyzed and compared.  The finite element method is used to establish and verify the results of the laboratory test. The results of the experimental and numerical tests gave a large load-carrying capacity, reduction in the stresses, excellent ductility and energy dissipation capacity, and remarkably improved damping ratio.

The semi-rigid steel frame-composite steel plate shear wall structure (SCSW) effectively improves the lateral stiffness of shear wall, making it possible to use the semi-rigid joint. In order to study the plastic failure mechanism of SCSW, a plastic model is established, in which the effects of the rotations of semi-rigid joints and yield deformations of infill steel walls on the energy consumption are considered. Based on that, a design method for the lateral ultimate strength is put forward and a nonlinear FEM model is setup using ANSYS. Through the comparison between plastic analysis results with the finite element results, it is shown that the plastic analysis method is feasible and has a safe redundancy.
