Abstract

The long-span spatial steel structure takes its complex construction process because of its features, such as large scale, wide range, and long cycle duration. Simultaneously, the structural construction process can not only affect the shaping of long-span spatial structure, but also produce a great effect to structural final force state, which makes the construction monitoring of long-span spatial steel structure necessary. The most important construction parts for Shenzhen Bay Stadium steel roof are unloading process and closure process. Considering the structure complexity in the construction phase, a structural health monitoring system was installed, which began to be built in early 2010 and contained two phases: construction monitoring and operation monitoring. In this paper, the temperatures and displacements monitoring in construction phase are firstly described in detail. The monitoring data of temperature and displacement measured in unloading and closure phases are then analyzed, respectively. According to these monitoring data, the comprehensive understanding for the structural performances in construction phase is shown and discussed, which can provide a reference of construction monitoring for the related projects.
