Non-Linear Analysis On The RC Structure Partially Disposed SRC Column

This thesis mainly researches whole performance of high-rise building disposed SRC column and partial stress,strain of SRC column,it belongs to the field of RC.The ground floor column's axial compressive force is especially big in high-rise buildings and skyscrapers . If using RC column ,it will lead short-column and "fat-column";if adopting steel structure ,it may reduce section area sharping,but its capacity of bearing erosion is weak,especially fireproof performance is its fatal weakness;SRC may not only reduce section area effectively,but also save steel,without the weaknesses in bearing erosion and fire-resistant capacity. So rearching SRC structure's performance is a primary task.This paper respectively computes RC structure and SRC structure by PKPM software series,contrastively analyzes the two schemes' aseismatic performance and ductility transforming capability when being undergos the action of frequently occurred earthquake and singularly occurred earthquake.Then this thesis analyzes the stress,strain and so on by ANSYS software. During the analysis by PKPM,first of all ,it checks that the story drifts of the two schemes are smaller than the relevant code's under frequently occurred earthquake and singularly occurred earthquake.By the contrast,it can be seen that the story drift angle of the scheme one is smaller average 1.1% than the one of the scheme two under frequently occurred earthquake and smaller average 4.3% under singularly occurred earthquake,it is obvious that aseismatic capacity of the scheme two is stronger under singularly occurred earthquake;The ductility ratio of scheme two is bigger 18.7% than the scheme one's, it is obvious that the scheme two has a better ductility.This paper contrasts the material fee and general economic benefit of a piece of SRC column and a piece of RC column.The result indicates that the SRC column is more advantageous than the RC column.This thesis analyzes the carrying force mechanism of SRC column by ANSYS software.The result shows that the co-work performance of profiled bar and RC is escellent in general time; profiled bar's stress is 12.5 times as much as concrete's.
