Performance Based Seismic Analysis Of Infilled Wall Frame Structure

There are well economic and adaptability of infilled-wall frame, and flexible layout. Therefore, it will be continue to a wide range in not a high-rise building structure design. Frame structure usually use infilled walls to dividing the house. In the past few decades, people mainly on seismic behavior of the main structure system, but neglect non-structural parts, the result is destruction of many buildings in earthquake damage. Infilled wall (plate) is the most important part of non-structural component. Especially in the frame work of flexible structure, non-structural view of the damage and losses caused by factors are not considered to be of secondary importance, and must be taken seriously. At present, the material of the infilled wall mainly used of lightweight concrete block and hollow masonry. Both lightweight concrete block and hollow masonry, structural framework of the mechanical properties with their accession will change. Overall framework of the quality of housing, stiffness, and the natural vibration compared to the overall deformation and displacement will be quite different from pure framework. The researchers conducted a study at home and abroad, but generally speaking, Filled wall frame structure of the study is still at a preliminary stage, a lot of work remains to be done.Therefore, this paper would combine infilled walls with reinforced concrete frame structures, mainly to the following studies:1,Establish nonlinear analysis model of infilled-wall frame structure ; Consider infilled-wall and frame work together, seismic response of the non-linear structural analysis model, and analyze the seismic response and the dynamic characteristics of the structure with the different layout of infilled-wall. Explored the seismic performance in infilled-wall andframe work together.2,Based on fatigue damage model, consider the stiffness degradation,the intensity degradation and the pinch, analysis of the infilled-wall frame structure with energy and the characteristics of injury, and the overall yield mechanism on structure,the sequence and the location of the yield plastic hinge and the quantitative understanding of the extent of plastic.3,In the theoretical framework of Push-over,use IDARC nonlinear analysis procedures to analyze the entire process of structural analysis,given Push-over curves;And comparison with the dynamic time-history analysis to further explore the effects of lateral load distribution.
