摘要
为研究基于CTM和Beam-Column Joint Element单元的钢筋混凝土梁柱节点核心区抗震仿真计算,本文先分析了CTM的计算原理和局限性,并对原计算模型进行调整;之后通过试验数据验证了调整前后模型的正确性,并通过参数分析得出调整前后CTM在不同参数下核心区抗剪强度的变化规律;最后通过对比理论计算与试验下核心区抗剪强度变化规律,证明调整后模型更为准确。
In order to research seismic simulation of core area in beam-column joint based on CTM and beam-column joint element,the calculation principle and limitations of CTM model are analyzed and the original calculation model is adjusted.Afterwards,the correctness of the models before and after the adjustment is verified by the experimental data,and the change rules of the shear strength of the CTM model under different parameters before and after the adjustment is obtained through parameter analysis.Then,by comparing the theoretical calculation and the experimental results,it is proved that the model is more accurate.Finally,by comparing the change rules of shear strength of the core area under the theoretical calculation and the experimental results,it is proved that the adjusted model is more accurate.
