Self-adaptive real-time hybrid simulation test loading method of space framework model

The invention discloses a self-adaptive real-time hybrid simulation test loading method ofa space framework model. In the invention, through a dual initial time lag compensation strategy of the initial time lag compensation and a self-adaptive loading section, the initial time lag of the system can be ensured to be close to 0 before seismic waves are formally loaded, and a problem of insufficientestimation and compensation of the initial time lag in a real-time hybrid simulation test is solved. In the invention, a space frame test substructure is equivalent to a test unit, and a signal conversion module is used for converting an overall displacement reaction corresponding to the test substructure in the overall model into a test substructure loading relative displacement actually fixed ona basis so that real-time loading of a large-scale space frame model with higher rigidity is realized. 本发明公开了一种空间框架模型自适应实时混合仿真试验加载方法，本发明通过初始时滞补偿和自适应加载段的双重初始时滞补偿策略，能够保证在正式加载地震波之前，系统的初始时滞接近于0，解决了实时混合仿真试验中对初始时滞估计和补偿不足的问题；本发明将空间框
