摘要
天津诺德英蓝国际金融中心采用巨型柱+剪力墙核心筒+环形桁架+伸臂桁架结构体系。钢板剪力墙作为新型高层钢结构抗侧力构件,受到焊接残余应力、动臂塔吊、液压爬模等施工荷载影响,产生较大竖向应力和变形。通过施工监测与模拟研究,分析钢板剪力墙内力变化规律,保证施工阶段安全,为工程科学施工提供指导。
A giant column ＋ shear wall core tube ＋ hoop truss ＋ extended truss structure system was used for Tianjin Noble Winland International Financial Center. As a new component to resist lateral force,steel plate shear wall is impacted by residual stress,tower crane,jumping formwork,which causing large vertical stress and deformation. By using monitoring and simulation,it was analysed steel plate shear wall＇s regulation of internal force change,with which the construction safety was ensured and a guidance for the project＇s scientific construction was given.
