Abstract

A new kind of beam string structure called RPC-BSS, which consists of reactive powder concrete upper chord and cables, is presented in this paper. The material of RPC provides superior mechanical properties and high durability, and the cable provides huge tensile force. The concept is based on the combination of the advantages of RPC and beam string technology. Furthermore, static and dynamic properties are discussed, and the influence of different factors is taken into consideration in the analysis. The analytical results show RPC-BSS is of longer span, less weight, better seismic characteristics and higher durability than conventional BSS. Keywords: RPC-BSS, reactive powder concrete, high durability.
