Abstract

Introduction:

For suspended-dome with big partial hole, two kinds of feasible plans were proposed.

Method:

One of the plans was to adjust suspended-dome’s members, and another to build auxiliary supporting system to support the suspended-dome with columns together. These kinds of suspended-dome’s main structural parameters include stiffness, member force, steel consumption, support reaction and stability, and parametric analysis is based on these parameters.

Conclusion:

Firstly,the scope of application was illustrated for the former plan. Then, an equivalent vertical stiffness algorithm was put forward for the latter plan. In the latter plan, limit stiffness constant was introduced to quantify the method for solving discontinuous support problem.

Keywords: Suspended-dome, Discontinuous Support, Parameterization, Equivalent Stiffness, Parameters, Single-layer shells.
