考虑初始缺陷的桥梁高大施工支架整体稳定性能研究

Jianzhu Gangjiegou Jinzhan
高大施工支架是大跨度复杂桥梁工程中常用的钢结构支撑系统。实际工程中由于受到高大施工支架加工安装误差、超限受力或不均匀受力等因素影响，因此钢结构施工支架存在节点连接不牢固、杆件弯曲变形等初始缺陷。为明确初始缺陷对桥梁高大施工支架整体稳定性能的影响规律，首先开展了桥梁高大施工支架的线性屈曲分析，进而探讨了节点半刚性、杆件初弯曲等初始缺陷对桥梁高大施工支架极限承载力的影响规律。为提高桥梁高大施工支架极限承载力的求解精度，引入刚度系数来衡量节点半刚性，综合考虑节点体对杆件计算长度的影响 ...

西宁机场新建T3航站楼中央C区网架施工关键技术

Jianzhu Gangjiegou Jinzhan
钢网架结构因其跨度大、自重轻等优势被广泛应用于大型公共建筑。西宁机场新建T3航站楼中央C区网架具有跨度大、高差大、自重大、悬挑长等特点，具有较高的施工难度。针对施工难题，该项目创新地采用“多阶扩展累积提升、虚拟轴+竖向旋转提升”组合提升技术，具有高效、精准、安全等优点。施工前通过SAP2000软件建模分析，获取结构应力、变形等关键数据，为施工方案提供可靠支撑。多阶扩展累积提升技术通过三级空中停滞、先高阶后低阶提升的方法，解决了错层施工难题，大幅减小高空作业与胎架用量，并缩短工期 ...
