AN ANALYTICAL STUDY ON RESTORING FORCE CHARACTERISTICS OF REINFORCED CONCRETE FRAMED STRUCTURES
|
抄録（英）：
In dynamic inelastic analyses of a structure, the restoring force characteristics are essential. Those ones in reinforced concrete structures are much influenced by brittle concrete, ductile steel and their interactions, and therefore it is difficult to follow the structural behaviours analytically. In this paper an analytical approach is developed which finds and appreciates restoring force characteristics of reinforced concrete framed structures based on the structural and cross-sectional geometry and the material properties without any structural experiments. Interactive bond actions between concrete and steel, correlative effects of axial force and bending moment on member stiffness and rigid body rotation including so-called "P-■ effect" are especially considered herein. Then it is applied to several model structures with aseismic elements different in arrangement and the results are discussed.
