Numerical Simulation of Shock Response and Dynamic Fracture of a Concrete Dam Subjected to Impact Load

open access: yesEarth Sciences Research Journal, 2016
The shock response and dynamic fracture of concrete gravity dams under impact load are the key problems to evaluate the antiknock safety of the dam. This study aims at understanding the effects of impact shock on the elastic response and dynamic fracture

Fracture analysis of concrete gravity dam under earthquake induced loads

open access: yesJournal of Applied Sciences and Environmental Management, 2011
In this paper, seismic fracture behavior of the concrete gravity dam using finite element (2D) theory has been studied. Bazant model which is non-linear fracture mechanics criteria as a measure of growth and smeared crack was chosen to develop profiles ...

Near fault and far fault seismic analysis of concrete gravity dam [PDF]

open access: yesJournal of Hydraulic Structures, 2020
Ground motions records of the past higher magnitude (Mw>5) earthquakes have indicated that ground motions recorded at the closest distance of the near-fault are very different from those recorded from a higher distance from the site of the far-fault ...

Thermal analysis of concrete gravity dam

open access: yesTạp chí Khoa học Đại học Mở Thành phố Hồ Chí Minh - Kỹ thuật và Công nghệ, 2012
In practice of massive concrete constructions, cracks appear so popularly. Thermal behavior in concrete is the important cause of this problem.Based on this reason, the thermal analysis of concrete is very neccessary to find the reasonable solution to prevent cracking in design massive concrete constructions, especially hydroelectric power because of ...

Seismic Damage Analysis of Concrete Gravity Dam Based on Wavelet Transform

open access: yesShock and Vibration, 2016
The key to the dam damage assessment is analyzing the remaining seismic carrying capacity after an earthquake occurs. In this paper, taking Koyna concrete gravity dam as the object of study, the dynamic response and damage distribution of the dam are ...
