Paper Title:
Unloading Analysis and Real-Time Monitoring of Steel Reticulated Shell in China University of Petroleum
  Abstract

Hyperbolic paraboloidal latticed shell, with a span of 93.6m, is adopted in the gymnasium of China University of Petroleum. Single-layer shell of the inner 9 circles adopts crossed web bars to increase its stiffness and bearing capacity, and double-layer shell of the outer 3 circles is used to bear horizontal action. Elastic support is employed to simulate hydraulic support of the shell, beam element to chords, and truss element to crossed web bar. Thus unloading program, from inside to outside and multiple cycles, is raised. To master the influence of unloading on the shell’s security, vibrating string extensometer and total station are used to monitor stress and vertical displacement of key points. By comparing theoretical data with monitoring results, it is proved that the shell’s stress and deformation comply with the design requirements, and indicated the success of unloading.
