Abstract: Suspened-dome structure is a new kind of hybrid space structure with the combination of an upper single-layer lattice shell and a lower cable-strut system, and has a very broad applied prospect.The research state of construction analysis is first introduced.The key problems in construction analysis are then pointed out, including determination of the geometric model and control of the prestressing force.Followed that, experiment of the scaled model is carried out and two construction schemes are proposed according to the pretension element, number of simultaneously pretension point and prestressing force level.The theoretical results are compared with that obtained form the experiment.The research here will provide a reference for construction of similar suspened-dome structures.
