ABSTRACT:

For suspen-dome structures, the construction process is very complex and may have an effect on its structural behavior during service time. During construction, a remarkable pre-stressing loss may be induced by sliding friction between hoop cable and cable-strut joint, and the sliding friction can be any value in construction stage and service time. In this paper, the effect of pre-stressing loss and sliding friction during construction on the structural behavior of suspen-dome structures is investigated. The analysis results show that the construction process has a remarkable effect on the structural behavior of suspen-dome structures and a security risk can be induced by it. Therefore, it is suggested that the construction process should be considered in the design process of suspen-dome structures.
