摘要
广州珠江新城西塔外框筒为巨型斜交网格体系,该结构体系中空间相贯X节点的实际力学响应特征对整个体系的承载能力尤为重要。为保证施工安全,从数值模拟及现场施工监测两方面对西塔结构施工过程中的X节点受力情况进行分析,结果表明,广州珠江新城西塔所采用的新型X节点在施工时处于弹性阶段,X节点构造合理,应力空间较大。
Mega crossing lattice system composed of concrete filled steel tubes is used in outer tube of Guangzhou Pearl River New Town West-tower,and the actual mechanical response characteristics of intersecting X node is very important to the capacity of this structural system.Numerical simulation and on-site construction of X node monitoring stress are analyzed.The results show that X node is in elastic stage during construction,X node structure is reasonable and the stress space is enough.
