we propose a reinforcement learning-based hyper-heuristic framework, dubbed RLHH, to enhance the performance of CG. RLHH is a selection module embedded in CG to accelerate convergence and get better integer solutions. In each CG iteration, the RL agent selects a low-level heuristic to construct...
the seismic behavior. Details of the test results are discussed to understand the specimens’ seismic performance in terms of general behavior, hysteresis loops response, and strain profiles of long- itudinal reinforcement. In the FE numerical study, the three-dimensional (3D) model developed is ...

The floor plan details of the reinforcement and cross-sectional dimensions that were used in the model frame are shown in Fig. 2. The middle column on the A-axis, namely, the side column of the model frame was removed when the model was built in the laboratory, but the corresponding ...
All specimens were designed using the similar geometrical, material, and reinforcement details, except for the slab shear reinforcement used.The first specimen, which is used as a control specimen, was designed using standard orthogonal stud rail for slab shear reinforcement. The slab shear ...
Eight test specimens of reinforced-concrete (RC) footings were constructed and tested to investigate the punching-shear behavior of the concrete footings with the developed details. The test parameters include the additional placement of a longitudinal reinforcement around the column-footing connections, ...
The test parameters were the reinforcement ratio of the beams and the interface details between the PC column and the PC beam shell. The test results showed that regardless of the test parameters, the RC-emulated beam-column connections exhibited good deformation capacities, which were comparable ...
For experimental investigations, two types of beam-column joint specimens, with ductile and brittle reinforcement detailing are cast and investigated in this study. The joint specimens are subjected to the cyclic displacements of increasing amplitude until failure. Post failure, the joint specimens are ...
