摘要 采用ansys有限元分析方法和应力迹线相结合的方法对薄壁花瓶墩建立"拉-压杆模型",提出了适用于薄壁花瓶墩的拉力计算实用公式,并探讨了影响薄壁花瓶墩"拉-压杆模型"中拉杆的抗力的相关因素,为薄壁花瓶墩设计和验算提供了有效而简便的计算方法. This paper establishes strut-and-tie model in thin-walled vase pier by using combination method of ansys finite element analysis and stress trace and proposes the practical and simplified method of tension of thin-walled vase pier.The relevant factors influencing resistance of tie bar in strut-and-tie model of thin-walled vase pier are discussed.An effective and simple calculation method is provided for thin-walled vases pier design and checking.
