摘要:
现有钢筋混凝土(RC)框架结构抗震性能分析大多采用刚性地基假定,未考虑土-结构相互作用的影响,而在实际地震中部分结构出现了"强梁弱柱"的失效情况,与以刚性地基假定分析的预期结果不一致。本文对某6层办公楼的一榀框架进行Pushover分析,探究了结构在刚性地基假定和考虑土-结构相互作用两种情况下的固有频率、顶点位移和塑性铰的产生和发展过程。结果表明,考虑土-结构相互作用后,RC框架结构自振周期变长,频率降低,结构顶点位移增大,结构底层柱铰增多;有效地再现了忽视土-结构相互作用而设计的框架结构在实际地震中出现"强梁弱柱"的情形,验证了在对结构进行Pushover分析时,考虑土-结构相互作用的必要性;并将动力时程分析与Pushover分析的结果进行对比,验证了Pushover分析的可行性和可信性。
Abstract:
Most of the existing seismic analysis of reinforced concrete (RC) frame structures was based on rigid foundation assumption, that ignores the effect of soil-structure interaction. The failure mode of "strong beam weak column" appeared in some RC structures in the actual earthquake, which is not consistent with the expected results that structures designed by rigid foundation assumption. In this paper, one frame of 6-story office building was analyzed by the method of Pushover, the natural frequencies, ultimate displacement of the vertices and the development of the plastic hinge under the condition of the rigid foundation assumption and considering soil-structure interaction were compared. By analyzing the results, after considering soil-structure interaction, the natural vibration period of RC frame structure become longer, the displacement of the vertices increases, more hinges appear at the column bottom of the structure. It can explain of the phenomenon of "strong beam weak column" during the real earthquake. The necessity of considering the soil-structure interaction during the Pushover analysis of the structure is verified. Comparing with the results from dynamic time-history analysis, the reliability and feasibility of the Pushover analysis method are proved.
