Unified stochastic and nonstochastic nonlinear analysis of composite steel concrete arch structures

Concrete-Filled Steel Tubular (CFST) arch structure is a composite structure which ingeniously integrates mechanical advantages of steel and concrete (Han et al. 2014) into an ensemble to serve multiple purposes in the development of modern society (Li et al. 2011, Wang et al. 2013). Extensive applications of CFST arch structures have demon strated the successful implementation of such innovative designs in contemporary bridges.
