在前期试验研究基础上,根据梁—墙平面内偏心连接节点非线性有限元分析,分析了此类节点梁纵筋的锚固性能。分析结果表明,梁—墙平面内偏心连接节点偏心一侧梁纵筋锚固性能低于不偏心一侧,节点宏观受力和梁纵筋局部锚固环境是影响节点纵筋锚固性能的关键因素,应通过合理设计保证梁纵筋锚固性能以满足节点传力要求。
Based on the previous experimental research, according to the nonlinear finite element analysis of the eccentric connection node in the beam-wall plane, the anchorage performance of the longitudinal reinforcement of such a beam is analyzed. The analysis results show that the anchorage performance of the longitudinally longitudinal beam on the eccentric side of the eccentric connection in the beam-wall plane is lower than that on the eccentric side. The macro-stress of the joint and the local anchorage environment of the longitudinal beam are the key factors affecting the anchorage performance of the longitudinal reinforcement. Through reasonable design to ensure the longitudinal reinforcement anchorage performance to meet the node force requirements.
