Dynamic Finite Element Analysis of RCC Gravity Dam
Advanced Materials Research, 2011Dynamic finite element analysis for a RCC gravity dam is implemented by using response spectrum method in this paper. Firstly, three-dimensional finite element model is established, and then the subspace iterative method is used in the modal analysis of the gravity dam.

Capacity and Benefit-Cost Relation for Concrete Gravity and RCC Dams
World Water & Environmental Resources Congress 2003, 2003The relationship between capacity and total net benefit of concrete gravity and roller compacted concrete (RCC) dams is investigated using benefit-cost analyses. The total capital cost of such dams is equal to the summation of costs of construction, engineering and consultancy services, right of way, and relocation of structures. Operation, maintenance

Seismic Damage Analysis of RCC Gravity Dams Using 3D Nonlinear FEM
Applied Mechanics and Materials, 2011The earthquake-resistance performance of gravity dam is an important indicator of dam safety. The earthquake-resistance performance of non-overflow monolith for Guanyinyan gravity dam is evaluated in this paper. First of all, the three-dimensional finite element model of dam is established by ABAQUS software.

The Parameter Inversion and Stress Simulation Analysis for High RCC Gravity Dam in Construction
Applied Mechanics and Materials, 2012Before and after pouring the concrete for a dam, how to predict and obtain the accurate temperature and stress of the various parts of the dam, is the key to prevent cracks in concrete. The stresses calculated from the parameters of the laboratory under the ideal conditions have obvious difference with the value calculated from site measured strain. As
