Compression Testing And Failure Modes Of Steel-Concrete Composite (Sc) Structures For Nuclear Containment, Patrick Michael Wanamaker, Amit H. Varma
Compression Testing And Failure Modes Of Steel-Concrete Composite (Sc) Structures For Nuclear Containment, Patrick Michael Wanamaker, Amit H. Varma
The Summer Undergraduate Research Fellowship (SURF) Symposium
Although being able to provide much cleaner power than burning coal and other fossil fuels, nuclear power plants are still a tough sell to the general public due to their history of being spontaneously dangerous. The containment structures surrounding these nuclear plants, however, can play a huge role in reducing the risks associated with them. Relatively new designs for these containment assemblies, known as SC (steel-concrete composite) structures, aim to increase the strength and durability of the containment facilities while keeping costs down. By varying the spacing between shear studs, the ratio of concrete to steel, and the ratio of …
Real-Time-Hybrid-Simulation Of Multi-Degree-Of-Freedom Systems With Multiple Time Steps, Lanxi Liu, Arun Prakash
Real-Time-Hybrid-Simulation Of Multi-Degree-Of-Freedom Systems With Multiple Time Steps, Lanxi Liu, Arun Prakash
The Summer Undergraduate Research Fellowship (SURF) Symposium
Computational simulation and physical experiments are both widely used in testing the response of a structure under earthquake loadings, but physical experiments can be expensive for large problems and numerical may result in the loss of important structural behavior caused by a large amount of assumptions. Real-time hybrid simulation (RTHS) is a combination of these two approaches, which uses both a numerical and physical substructures that interact in real time to simulate structural behavior. The numerical and physical substructures are connected using a transfer system that enforces compatibility between them. The physical substructure needs to be run at a very …
Recursive Multi-Time-Step Coupling Of Multiple Subdomains, Yukun An, Payton Lindsay, Xiaowo Wang, Arun Prakash
Recursive Multi-Time-Step Coupling Of Multiple Subdomains, Yukun An, Payton Lindsay, Xiaowo Wang, Arun Prakash
The Summer Undergraduate Research Fellowship (SURF) Symposium
The need for efficient computation methods for modeling of large-scale structures has become critically important over the past few years. Efficient means of analysis often involve coupling in space through domain decomposition and multi scale methods in time. The multi-time-step coupling method is a coupling method in time which allows for efficient analysis of large-scale problems for structural dynamics where a large structural model is decomposed into smaller subdomains that are solved independently and then coupled back together to obtain the global solution. For coupling of more than two subdomains that are solved at different timesteps, we employ recursive methods. …
