Description
Technical Field
The invention relates to the technical field of shock absorption and isolation of a gym bucket screen structure, in particular to a modular shock absorption device for modifying an existing gym tuning mass damping bucket screen.
Background
The earthquake is that the stratum is in a complex stress state, when the earth stress exceeds the limit strength of the stratum at a certain place along with the continuous change of the earth crust, the stratum is suddenly broken and dislocated, so that vibration is caused, the vibration is transmitted to the ground surface in the form of elastic waves, an object with certain mass near the ground surface is caused to generate inertia force, and when the earthquake resistance of the object against the inertia effect is insufficient, the object is damaged. The damage to the object is more serious when the excellent period of the local vibration is relatively close to the self-vibration period of the object. The self-vibration period of the object can be obviously changed by arranging a certain vibration isolation device on the object, so that the excellent period of the earthquake is avoided, the inertia force acting on the object is obviously reduced, the damage of the object under the action of the earthquake is reduced, and the safety of the object under the earthquake is improved.
Conventional seismic isolation and reduction techniques are generally divided into two main categories: the self-vibration period of the structure is prolonged through the arrangement of the vibration isolation device, and the earthquake response of the upper structure is reduced; the other type is that energy input of the earthquake to the structure is consumed by arranging an energy consumption device at the joint of the structure and the foundation, so that the earthquake energy input into the structure is reduced, and the damage of the earthquake effect is reduced. At present, both techniques are well applied. For a large-span space structure, the acceptance mechanism is complex, and participation in three orthogonal directions in the earthquake process cannot be ignored, so that the application of shock insulation is very difficult. However, the seismic energy input by the motion of the additional mass can be dissipated by providing an additional mass system in three directions of the structural ball node, thereby increasing the shock resistance of the large span space structure.
