Stress-free-state based structural analysis and construction control theory for staged construction bridges - 2020
Shunquan Qin, Kai Wei, Jingxi Qin, Renan Yuan, Leiping Xu, Qilian Dan
AbstractStructural analysis and construction control of staged construction process is a major subject for modern long-span bridges. This paper introduces the concept of stress-free-state variable of structural elements and deduces the mechanical equilibrium equations and geometric shape governing equations for staged construction structures utilizing the minimum p...... hiện toàn bộ

Finite element analysis of reinforced concrete curved box-girder bridges Tập 4 Số 1
Preeti Agarwal, Priyaranjan Pal, PK Mehta
AbstractThe study presents the design forces of simply supported single-cell reinforced concrete (RC) curved box-girder bridges using a finite element method (FEM) based CSiBridge v.20 software. An existing model has been used to validate the present modelling approach. Models subjected to vertical loading, i.e., dead load (DL) and Indian road congress live load (L...... hiện toàn bộ
