At present, mild steel damper, due to good Hysteresis Behavior, has structure lateral resistant member and the dual function of earthquake-proof safety silk concurrently, is widely used in each class formation in highlight lines area. Antivibrator is different from general structure component, strictly controls the yield displacement of component during design. If disposable installation by antivibrator puts in place, owing to the shrinkage stress of concrete setting and the slow of structure self settle, antivibrator is easily generated primary stress, affects the performance of anti-seismic performance. Therefore design antivibrator is connected with the reasonable of agent structure, it is to avoid the generation of initial imperfection is particularly important.
At present, common in engineering mild steel damper type of attachment is that built-in fitting adds welding or pin-connected joint. Welding node adds Site Welding workload, and is inconvenient to change. Although pin-connected joint eliminates the weld job at scene, but needs to open silk mouth on embedded board, and the required precision made and install is high, slightly deviation will cause that bolt cannot pass.
