Dynamic failure analysis of concrete dams under air blast using coupled Euler-Lagrange finite element

Farhoud KALATEH

Frontiers of Structural and Civil Engineering 2019, Volume 13, Issue 1,   Pages 15-37 doi: 10.1007/s11709-018-0465-7

Abstract: In this study, the air blast response of the concrete dams including dam-reservoir interaction and acousticdams.Numerical results revealed that 1) concrete arch dams are more vulnerable to air blast loading than concretegravity dams; 2) reservoir has mitigation effect on the response of concrete dams; 3) acoustic cavitationintensify crest displacement of concrete dams.

Strengthening of the concrete face slabs of dams using sprayable strain-hardening fiber-reinforced cementitious

Frontiers of Structural and Civil Engineering 2022, Volume 16, Issue 2,   Pages 145-160 doi: 10.1007/s11709-022-0806-4

Abstract: slabs in a concrete-face rockfill dam (CFRD) for the first time.It was found that the FRCC layer improved the flexural performance of concrete slabs significantly.The cracking and ultimate loads of a concrete slab with an 80 mm FRCC layer were 132% and 69% higherthan those of the unstrengthened concrete slab, respectively.144% higher than that of the unstrengthened concrete slab.

Zhu Bofang

Strategic Study of CAE 2006, Volume 8, Issue 7,   Pages 21-29

Abstract:

The number, the height and the size of concrete dams under construction in China are the biggest onesSome important problems about concrete dams are discussed in this paper: (1) The key technique for terminatingto dam. (3) Concrete mark based on 90 d or 180 d age is more appropriate for concrete dams than concreteclass based on 28 d age . (4) The safety factor for compressive stress for the specially heigh concretearch dam (higher than 200 m) is some what low in China (5) The equivalent stress in arch dams analysed
