DIANA Modeling Cases for Precast Segmental Structures

Abstract

Precast segmental structures are widely applied in current engineering owing to their rapid assembling efficiency, excellent quality control, low life-cycle cost and mitigated environmental disturbance. In this chapter, the focus of numerical simulation is put on precast segmental specimens. Targeting at the current emerging structures such as precast segmental bridges, various issues such as direct shear failure, bending failure and long-term deterioration are written as numerical engineering cases. Modeling methods for precast segmental structures in different joint shapes (shear keys as well as corbel joints) are also illustrated in this chapter. Moreover, as one of the unique and typical features for DIANA software, random field concerning forecast of precast segmental girders is specifically displayed in this chapter.
