EQUIVALENT OBLIQUE COMPRESSION BAR MODEL OF MULTI-RIBBED COMPOSITE WALL
According to the results of previous studying, the elastic simplified mathematical mode of the multi-fibbed composite wall, which is the main bearing member of a new structural system-multiribbed slab structure (MRSS), is studied. Based on the experimental research on the frame grid elements of the wall, the paper discusses the influence of the main factors on the mechanical behaviors and failure modes of the frame grid elements, such as the stiffness of beams and columns in frames, the mechanical properties of filling materials and others; The oblique compression bar which diagonally articulates with reinforced concrete frame is adopted to simulate the action of filler block on the whole wall, and the width formula of the equivalent oblique compression bar is obtained; On this basis the rigid frame-oblique compression bar simplified mathematical model which is suitable for the multi-fibbed composite wall is established; Moreover, the elastic lateral rigidity formula of the rigid frame-oblique compression bar is deduced. Theoretical analysis shows that the rigid frameoblique compression bar can better reflect the real mechanical behavior of the multi-ribbed composite wall and is a kind of reasonable simplified mathematical model.
