Experimental study on strengthening interior beam column joints in reinforced concrete structures using wing walls

The test results validated the feasibility and effectiveness of strengthening interior beam‒column joints via the wing wall installation method. In the design for practical engineering strengthening, it is essential to first assess whether the joints of the existing structure require strengthening. If strengthening is deemed necessary, the extent of reinforcement must be determined; specifically, the […]

Reinforcement learning control of a biomechanical model of the upper extremity

Below, we first provide details on our biomechanical model. After discussing our general reinforcement learning approach, we focus on the individual components of our method, namely states, actions, scaling factors, rewards, and an adaptive target-selection mechanism. We also provide details on the implementation of our algorithm. Finally, we discuss the methods used for evaluation. Biomechanical […]
