In this paper, we propose an assembled self-centering buckling-restrained brace (ASCBRB), which eliminates the residual drift of structures after a major horizontal displacement. The ASCBRB also represents advanced device for partial replacement damaged parts brace. Four groups prestressed disk springs and metal yielding core plate were used to improve resilience energy dissipation brace, respe...

What does one do when they are desensitized to their vibrator and need to check a consumer report before investing in a new one?-Rocking and rolling Answer Dear Rocking and rolling, Consumer Reports? has not yet rated vibrators and other sex toys; fortunately, other resources do have useful information. You can check out different types of vibrators and/or other sex products at the following on...

An innovative lateral force resisting system is investigated that allows steel braced frames to uplift and rock on their foundation, partially isolating the frame. Passive energy dissipation devices are implemented at the uplifting location to control the rocking response to within allowable limits. The structure’s gravitational forces provide an inherent restoring force during the rocking resp...
