Description

A kind of metal friction-surrender damper structure
Technical field
The utility model belongs to building engineering structure anti-seismic technology field, relates to a kind of structure with metal yield and frcition damper, realizes the self-regulating function of damper, reaches the purpose of the extraneous input structure energy that dissipates stage by stage.
Background technology
Earthquake can cause the heavy damage of building structure as one of natural calamity.Traditional seismic design is to resist geological process by the anti-seismic performance that strengthens structure self, and promptly utilize structure storage itself and earthquake energy to satisfy the structural seismic standard of setting up defences: little shake is not bad, and middle shake can be repaiied, no collapsing with strong earthquake.And this antidetonation mode lacks capacity of self-regulation, under uncertain geological process, does not satisfy the requirement of safety probably.The energy-dissipating and shock-absorbing technology is provided with damper with the increase structural damping as a new technology that develops rapidly by the suitable position in building structure, thereby reduces the reaction of structure under wind and geological process.Verified this technology of achievement in research in recent years is effective, practical.
The energy-consumption shock-absorption device that has had at present is a lot, as metal yield damper, frcition damper, viscous fluid damper, intelligent damper.Wherein the metal yield damper mainly is that good plastic property absorbs seismic energy after utilizing metal yield, and frcition damper normally utilizes the seismic energy that dissipates of the frictional behavior between the metal.Two kinds of energy-dissipating device something in commons are all can adopt common metal (as steel) to process; All belong to Passive Control system category, damper itself does not need the input of extra power; Draw materials simple, easily processing, hysteresis stable performance, be easy to replacing etc.Its weak point is: all lack the self-adjusting ability of control during two kinds of dampers use separately, can not adjust the size of sinker control according to building structure at the response characteristic under the geological process.And building structure is when suffering geological process; its destructive power is not of uniform size; damper is as important energy dissipator; aspect power consumption, should provide different controls according to the difference of earthquake intensity; as the less control that adapts to it can be provided under little shake effect; the whole abilities of performance energy dissipator consume energy protection agent structure stage by stage under middle shake, big shake effect.
Summary of the invention
The purpose of this utility model provides a kind of metal yield-frcition damper structure, by frcition damper and metal damper series parallel are used, realize the self-adjusting ability of damper, reach the damping control thought of segmentation power consumption, reduce the reaction of structural system under geological process, solve the safety issue of building structure under geological process.
The technical solution of the utility model is as follows:
Metal yield damper upper end is connected by welding manner with following friction steel plate, and hole slot is offered on the friction steel plate surface, realizes the tunable performance of damper by the hole slot length adjustment; Connect with high-strength bolt between two friction steel plate, when relative deformation does not surpass hole slot length, provide power consumption by the frictional force between the friction steel plate; When relative deformation surpassed hole slot length, the metal yield damper began to deform, and by the plastic property power consumption of metal, finally realized the segmentation energy dissipation behavior of damper.
Effect of the present utility model and benefit are mainly reflected in metal yield damper and the friction damper associated self-adjusting ability that is used for increasing damper that makes, and realize the power consumption stage by stage of damper.This building method is simple and practical, is easy to the seismic design of energy-dissipating and shock-absorbing structure, will more be widely used in the Anti-quake Architectural Structure Design field.
