ABSTRACT

A new prestressed spatial steel structure system--cable supported barrel vault structure system is proposed in this paper. Firstly, the prestress design method for the structure is proposed. Then, we present in-depth analysis on the proposed structure. Research results suggest that the cable supported barrel vault is an efficient spatial steel structure system with improved rigidity, reduced horizontal arch thrust and well controlled horizontal displacement. The influence of several key parameters on the mechanics characteristics of the cable supported barrel vault is evaluated as well. The following conclusions are drawn from our study: (i) the impact of the rise-span ratio on the mechanics characteristics is significant, so the rise-span ratio should be designed properly. Values from 0.08 to 0.12 are suggest; (ii) the influence of the sag-span ratio is also great. The sag-span ratio with range from 0.02 to 0.06 is suggested; (iii) the impact of the strut number on the mechanics characteristics is small. The strut   number is usually determined by the span of the structure. Generally speaking, the longer the span is the larger the strut number should be. Struts should be used as few as possible while meeting the safe standards, but the strut number should be more than one.
