RMC Structural Suite

The U.S. Army Corps of Engineers (USACE) Risk Management Center (RMC) developed a set of toolboxes to help dam and levee safety risk assessors perform pseudostatic analysis with sliding calculations, as well as assess seismic risks of concrete gravity dams. This suite also contains software from UC Berkeley used to obtain stresses, displacements, and base sliding of gravity dams subjected to free-field ground motion, as well as software from the USACE Engineering Research and Development Center (ERDC) to express the computed stability results for an idealized two-dimensional cross section of a rock-founded concrete gravity dam in terms of fragility curves for the potential modes of failure (e.g., sliding, overturning).

Coming Soon.		Coming Soon.		A numerical method has been implemented in a computer program, EA GD-SLIDE, to evaluate the earthquake response of concrete gravity dams, including sliding at the interface between the base of the dam and the foundation rock surface. The analysis method uses the hybrid frequency-time domain procedure, which accounts for the nonlinear base sliding behavior of the dam and the frequency-dependent response of the impounded water and the flexible foundation rock, to solve the equations of motion. The program can be used to obtain stresses, displacements, and base sliding of gravity dams subjected to free-field ground motion.		GDLAD is an acronym for Gravity Dam Layout and Design. GDLAD_Foundation is software for expressing the computed stability results for an idealized two-dimensional cross-section of a non-overflow concrete gravity dam embedded in rock in terms of a fragility curve for a potential sliding mode of failure. Within the Corps, the term system response curve is used to describe what is commonly referred to in the technical literature as the fragility curve; used for the hydrologic fragility assessment of concrete gravity dams embedded in rock. Uncertainty in strength, rock joint parameters that impact the flow of water within the rock joints, silt induced earth pressure and (post-tensioned) anchor force(s) are accounted for in a multivariate probabilistic stability analysis resulting in the computation of a system response curve.
This is the RMC Concrete Gravity Dam Toolbox version 1.0.		This is the RMC Pseudostatic Analysis with Sliding Toolbox version 1.0.		This is the EAGD-Slide version 1.0 from 1994.
