Description
Technical Field
The invention belongs to the technical field of building structure anti-seismic structures, and particularly relates to a swinging self-resetting steel frame based on an energy consumption damper and an assembly method of the swinging self-resetting steel frame based on the energy consumption damper.
Background
At present, the anti-seismic design of a steel frame mostly follows the design idea of 'strong node weak members', the idea is more focused on protecting the life without collapse of a main structure under the action of an earthquake, and the consequence that the structure cannot bear the original use function for a long time after the earthquake is ignored. The earthquake damage of the past shows that the structural design can not only meet the requirement of protecting life safety when an earthquake occurs, but also put the self repair of the structure after the earthquake and the recovery of the original function at the same important position so as to ensure the quick recovery of life and production in a disaster area. Therefore, domestic and foreign scholars continuously provide the function recoverable structure to solve the problems of overlarge residual deformation and overhigh repair cost of the building after the earthquake, so that the building has the self-resetting function, can recover quickly after the earthquake, and greatly reduces the economic loss caused by the earthquake. The self-reset structure with the swinging energy consumption function is a typical structure form capable of realizing function recovery, the structural component capable of providing reset force for the structure is introduced to control and reduce the residual displacement of the building structure after an earthquake, the node is loosened to realize the swinging function, the damage under the earthquake action is concentrated on an external energy consumption element, the self-reset capability is provided by utilizing a post-tensioning rib or a steel strand, and the energy consumption element can effectively reduce or even eliminate the residual deformation of the structure, so that the structure can be recovered to the original state after the earthquake through less repair or without repair.
Shape Memory Alloys (SMA) are known for their excellent self-resetting properties, high damping power consumption and unique Shape Memory effect. The characteristics meet the application requirements of the civil engineering anti-seismic field on the structure, and the residual displacement of the structure after the earthquake can be effectively reduced. In addition, because the SMA has excellent self-resetting performance and anti-fatigue capability, the SMA component does not need to be maintained and replaced even when the earthquake intensity is high.
The controlled swinging self-resetting steel frame has the characteristics of a self-resetting structure and a swinging structure, and the column base is allowed to be lifted under the earthquake action by loosening the column base node, so that the structure has good earthquake resistance by utilizing the self-resetting capability provided by the post-tensioning ribs or the steel strands. However, although the swing steel frame can effectively reduce earthquake damage, the larger swing deformation increases the overturning moment, the constraint action of the foundation on the column base is limited, the anti-overturning capability of the structure is reduced, the risk of the structure overturning is increased, and the exertion and the application of the anti-earthquake performance of the structure are not facilitated. Therefore, it is necessary to solve the problems of excessive sway of the sway column and limited restraint of the foundation on the column shoe.
