摘要:
为了研究蒸压无石棉纤维素纤维水泥板(CCA板)填充墙对钢框架结构受力性能的影响，对纯框架和带CCA板填充墙钢框架进行了低周往复加载试验，并利用有限元软件ABAQUS进行了模拟分析。根据试验及有限元模拟结果对带CCA板填充墙钢框架的承载能力、抗侧刚度和耗能能力等抗震性能指标进行了分析。结果表明：在低周往复荷载作用下，CCA板填充墙提高了钢框架结构的承载能力、抗侧刚度；CCA板填充墙参与了钢框架结构的滞回耗能，带CCA板填充墙钢框架的累积耗能能力明显优于纯框架；与纯框架相比，带CCA板填充墙钢框架的初始刚度有所提高；当位移角达到某一限值时，CCA板填充墙的损坏会引起钢框架结构的刚度发生突变，钢框架结构非弹性设计不应考虑CCA板填充墙对钢框架结构刚度的提高作用；所得结论可为带CCA板填充墙钢框架的工程应用提供参考。
Abstract:
In order to study the influence of cellulose fiber cement autoclaved plate (CCA plate) infill wall on the mechanical behavior of steel frame structures, the low frequency cyclic loading tests of steel frame and steel frame infilled with CCA plate were done. The steel frame and steel frame infilled with CCA plate were simulated by the finite element software ABAQUS. The bearing capacity, stiffness, energy dissipation capacity and seismic performance index of steel frame infilled with CCA plate were analyzed according to the results of test and finite element simulation. The results show that CCA plate infill wall will enhance the bearing capacity, lateral stiffness of steel frame. The CCA plate infill wall is involved in hysteretic energy dissipation of steel frame structure. The energy dissipation capacity of steel frame infilled with CCA plate is significantly better than that of the steel frame. Compared with steel frame, the peak load and initial stiffness of steel frame infilled with CCA plate are improved. When the drift angle reaches a certain limit, the stiffness of steel frame structure will suddenly change due to the damage of CCA plate infill wall, therefore the influence of CCA plate infill wall on the stiffness of steel frame structure shouldn’t be considered in the structural inelastic design. The results can promote the application of steel frame infilled with CCA plates.
