柔性传感器辅助下的郑州中原国际会展中心施工模拟与监测
Construction simulation and monitoring of Zhengzhou Zhongyuan International Exhibition Center assisted by flexible sensors
摘要
Abstract
A comprehensive simulation and monitoring of the entire construction process for the primary steel structure of Zhengzhou Zhongyuan International Exhibition Center was conducted.Through full-process nu-merical modeling,the impacts of temporary support removal and thermal effects were analyzed,and the critical stress regions of the structure were identified.To overcome the limitations of conventional sensors in achieving conformal contact with complex welds for refined monitoring,flexible sensors were deployed to monitor the de-formation of critical welded joints.The results demonstrate that the measured maximum stress during the con-struction phase remains below the design strength of steel,with the stress ratio controlled to be within 0.7,and the maximum deflection is less than the specification limit.While the temporary supports can effectively de-crease the internal forces and deformations during assembly,their removal triggers an approximately 3-fold in-crease in peak stress and a more than 7-fold escalation in mid-span vertical deflection.Thermal fluctuation ex-erts a profound influence on the internal forces,with the maximum stress fluctuation amplitued of 50 MPa.No-tably,the solar-induced temperature gradient between the upper and lower chords significantly exacerbates the stress disparities in the mid-span diagonal webs,highlighting a critical focus for thermal control during con-struction.关键词
