Interaction Analysis of Infilled Frame Structures under Lateral Loads

Filler stiffness and confinement effect on the frame structure under horizontal loads, making the earthquake severely damaged in recent years with filler frame structure. Research shows that the actual stiffness frame structure with infill walls and internal force distribution and pure framework significantly different. In this paper, the equivalent model analysis bracing frame structure filler with actual stiffness, elasticity and structure from stage to stage of the internal forces shaping the distribution were analyzed. The results show that the stiffness of the contribution and the confinement effect filler by factors geometry, masonry materials, the impact of the framework is not the same, need to consider the specific analysis and structural design.
