矩形钢管轻骨料混凝土框架抗震性能试验研究
|
摘要
本文以柱截面含钢率、梁截面形式为参数,进行了2榀内填轻骨料混凝土的方钢管混凝土柱-矩形钢管混凝土梁框架、2榀方钢管轻骨料混凝土柱-工字型钢梁框架在恒定轴力与低周水平反复荷载共同作用下的试验,研究了该类框架的受力性能和滞回曲线、延性、耗能能力、刚度与强度退化等抗震性能,分析了不同参数对该类框架受力性能的影响规律。研究结果表明:矩形钢管轻骨料混凝土框架的滞回曲线较为饱满,没有明显的捏缩现象,表现出良好的抗震耗能能力;各试件位移延性系数在3.00～3.74之间,能量耗散系数在1.438～2.324之间,表明内填轻骨料混凝土的矩形钢管混凝土框架结构具有良好的塑性变形能力和抗震耗能能力;随着柱截面含钢率的增大,框架的承载力、延性和耗能能力有不同程度的提高;在相同柱截面含钢率情况下,采用工字型钢梁的框架与采用矩形钢管轻骨料混凝土梁的框架相比,延性与耗能能力有小幅的提高,刚度退化较为平缓。
在试验研究的基础上,利用有限元分析软件ABAQUS对本文框架模型进行非线性有限元分析,结果表明理论分析与试验结果吻合程度较好。在此基础上,对柱截面含钢率、钢材屈服强度、混凝土强度、轴压比等影响矩形钢管轻骨料混凝土框架受力性能的主要因素进行分析,得到各参数对框架荷载-位移关系的影响规律,为矩形钢管轻骨料混凝土框架的抗震设计提供依据。
根据研究分析结果可知,矩形钢管轻骨料混凝土框架结构的工作性能满足结构抗震的要求,具有良好的应用前景。
Two lightweight aggregate concrete filled square steel tube column-rectangular steel tube beam frame test specimens and two lightweight aggregate concrete filled square steel tube column-steel beam frame test specimens were experimentally studied under constant axial load and cyclically lateral load. The steel ratio of column section and the form of beam section are considered as experimental parameters. And the seismic behavior such as displacement hysteretic curves, deformation ductility, energy dissipation, strength deterioration and stiffness degradation are researched. The examination results show that the lateral load versus lateral displacement hysteretic curves of the frames are plump shuttle shape, this indicates the frames have excellent seismic behavior; The deformation ductility coefficients are between 3.00 and 3.74, the energy dissipation coefficients are between 1.438 and 2.324, these explain the frames have excellent ability of deformation ductility and energy dissipation; The capacity, ductility and energy dissipation have obvious exaltation with the increase of steel ratio of column section; The frames which adopt steel beam have stable later capacity and excellent deformability ability under the same steel ratio of column section.
Based on the experimental testing, the nonlinear finite element analysis using ABAQUS for lightweight aggregate concrete filled rectangular steel tube frame is carried out. The result shows that the theoretical analysis coincides the experimental testing better. Then, the factors which affect the P-Δcurve of lightweight aggregate concrete filled rectangular steel tube frame such as the steel ratio of column section, steel strength, concrete strength and axial load level of column were analyzed, and the laws which each factor affects were obtained. The study results can provide some foundation for the seismic behavior design of lightweight aggregate concrete filled rectangular steel tube frame.
In sum, the research results show that the working capability of lightweight aggregate concrete filled rectangular steel tube frame can meet the requirements of seismic behavior, and this kind of frame has broad prospect for application.
