<p>The John F. Kennedy Center for the Performing Arts is located on the banks of the Potomac River in Washington, D.C. The Kennedy Center is home to the National Symphony Orchestra, the Washington National Opera and The Suzanne Farrell Ballet. In addition to being the nation's busiest arts facility, the Kennedy Center is also a "Living Memorial" to President Kennedy. The south expansion of the Kennedy Center, known as the REACH, provides much needed educational and rehearsal space, as well as a pedestrian link to the nearby Memorials.</p><p>The new structure combines practicality, versatility and innovation. Each surface and space created is unique, forming complex geometries and large span to depth ratios. The cast-in-place concrete structure is exposed on the interior or the exterior, including three white concrete pavilions rising out of the landscaped substructure. The pedestrian bridge connects the Kennedy Center to the river with over a 35-to-1 span to depth ratio. The REACH is scheduled to open in the Fall of 2019.</p>

Complex structural pattern and behavior of Large-span steel structure result in famous research of health monitoring technology of this kind structure all over the world. Health monitoring to key parts of large-span steel structures during the construction and service process grasp the stress situation, which can ensure the safety of structures. In this paper, health monitoring project of Jinan Olympic Sports Center is introduced and the basis of test points’ layout is elaborated in detail. The result shows that the system designed is running stable, which means it has certain application value to other health monitoring to major engineering.

The health monitoring and diagnosis of the major engineering structure is increasingly extensive attention from all the community. In particular, for the complex large-span steel roof unloading process, it is important especially. The unloading process will cause the change of structure stiffness include the internal force redistribution. The real-time and on-line monitoring have been applied to Xining stadium of the stress in the process of unloading for the purpose of structural health assessment in the paper, so as to achieve the purpose of the early warning of the problems which may arise in construction process. At the same time, through the comparison of the finite element software ANSYS analogue simulation and the value of the actual, it is obtained for the quality problem of steel structure in the process of unloading.
