“…Therefore, using the central steel plate improved the performance of the structure against the applied lateral load. In 2019, M. Ismail [11] presented a new elastoplastic bracing method called AR-Brace for passive structural vibration control. It consisted of five deformable elastoplastic components, which were four arcs in tangential contact with a central ring.…”

This paper presents cable bracing with a new configuration so that all cables remain in tension. For this purpose, a diamond cable bracing system comprising cables and rings is proposed for steel frames. The use of cable bracing is due to its advantages, such as high tensile strength and lack of buckling in evaluation with traditional braces. The proposed method can be installed easily for existing structures. Also, the cable is lightweight, and it has delicate dimensions. Sap2000 software was used to model the cables and rings. It was found that the proposed system eliminated the main weakness of the x-shaped cable bracing system. Increasing or reducing the diameter of the cables can control the displacement. Among the studied models, MRF has the least amount of axial force applied to the beams . A large amount of axial force is added to the floor beams by adding steel cable braces to the frame. In this case, by increasing the diameter of the cables, the amount of this force can be reduced.

“…Structural damping is a new method that has been proved effective in reducing the seismic response of structures [13][14][15][16]. The most mature and popular damping technique is seismic energy dissipation, which is simple in structure, cheap in cost, and easy to use.…”

This paper aims to develop a system to control the vibrations of ancient pagodas without damaging their original appearance. Taking the Small Wild Goose (SWG) Pagoda (Xi'an, Shaanxi Province) as the target structure, the authors designed a shape memory alloypendulum damping system (SMA-PDS) based on the theory of pendulum damping and the super elasticity of the SMA. To verify the effect of the SMA-PDS, a 1:10 scale model was created for the SWG Pagoda, and subjected to shaking table tests with and without the SMA-PDS. The test results indicate that: the small and flexible system can be installed easily inside the pagoda to dampen seismic vibrations; the SMA-PDS greatly reduced the acceleration response at the top of the SWG Pagoda model; the reduction is particularly prominent (32.5%), when the SMA wires had a pre-strain of 3%; the SMA-PDS worked better in medium and large earthquakes than in small earthquakes. To sum up, this paper provides a novel damping system for seismic vibration in ancient pagodas, shedding new light on the energy dissipation, vibration control and reinforcement of similar ancient pagodas.
