Abstract


Infilled wall frame structure is a very common structure, widely used in all types of building forms, A large number of infilled wall frame structures were destroyed in varying degrees of damage in the previous earthquake. At present, the research on test study and theoretical analysis of clay brick infilled wall frame structure is sufficient.However, since the use of clay block has been limited after wall innovation in China, lots of blocks made of various materials were used for infilled wall. And the related studies have not in step. Furthermore, research on the frame structures with non-structural measures such as steel tie bar, constructional column, horizontal constructional girder is not much. Therefore, related seismic behavior test and theoretical analysis has been done on the frame structures in this paper, which use autoclaved lightweight aerated concrete block (ALC) as infilled wall besides with non-structural measures such as steel tie bar, constructional column, horizontal constructional girder.By considering the infilled wall participated in frame carrying load, to use the commonly-used autoclaved lightweight aerated concrete block (ALC) in infilled wall frame structures. The comparison of pseudo-static tests under low-cycle reversed load of 4 frame structures with non-structural measures such as steel tie bar, constructional column, horizontal constructional girder and 1 frame structure for comparison are carried out. The results of the tests show that the frame structures with different non-structural measures, compared with common frame structure, its bearing capacity, hysteretic characteristics, energy dissipation capacity, rigidity degeneration, displacement ductility improved to a certain extent.Through the experimental research on frame structures, the nonlinear analysis of masonry-infilled frame structures with different constructional measures are carried out. The results are in good agreement with the experiment, laying a foundation for the further research. Parameter analysis of the number of constructional column and connection method of constructional column with frame structure are carried out. And analyzed the influence of set of constructional column on the mechanical performance of masonry-infilled frame structures.On the based of the nonlinear analysis and experimental research of the frame structures with non-structural measures, some design advise are presented for engineering design reference.
